Trinity Sunday: a preacher's nightmare

Trinity Sunday, year B
Trinity Sunday has often been called a “ preacher’s nightmare”.  What can we possibly say about the Trinity, the single greatest mystery of our faith? When we do pluck up the courage to say something about the Trinity, we easily risk falling into some heresy or another. Though I feel some of this pressure, I personally enjoy preaching on Trinity Sunday for one simple reason: I am a nerd. My preaching professor always told us that we should keep our homilies practical and down to earth. We were told to avoid Churchy and theological talk. But today, Trinity Sunday, is an exception. Today we get to be nerds! So let’s talk Trinity theology today.


If we want to talk about the Trinity we need to start with Jesus. Though you will not find the word “Trinity” in the Bible, it is Jesus who revealed to us this belief. During His ministry, Jesus was clear that He had been sent by the Father. This assertion did not differentiate Him from any other prophet like Moses or Isaiah. Jesus, however, went further. With His words and actions He claimed to be God. He forgave sins, something only God could do. He felt at liberty to add to the Law. God alone is the lawgiver. He said that He and the Father are one. After His Ascension, Jesus promised that He and the Father would send the Holy Spirit, who was not just a gift from God but was in fact God Himself. During His life, therefore, Jesus revealed to us our belief in the Trinity: God is only one, but He exists in three persons, Father, Son and Holy Spirit.


Jesus’ revelation of the Trinity, which we take for granted today, was extremely controversial among His contemporaries. His words were met with confusion and open hostility. For Jews, the single most important thing that they believed was that God is one. This is expressed in the Shema, the famous Jewish credal formula:
Hear, O Israel: The LORD our God, the Lord is one. And thou shalt love the LORD they God with all thy heart, and with all thy soul, and with all thy might. (Deut 6:4-5)
1st century Jews were their guard against any teaching that took away from the unity of God. Jesus’ words would have seemed like blasphemy to them.


For this reason, early Christians - most of whom were Jews - struggled to comprehend the Trinity. How could God be one and three? Reflection on this is already present in the New Testament. An incredible insight into this mystery is found in 1 John: God is love (1 John 4:8). It does not say that God, like us, loves or is lovable, but that He is love. From all eternity, before anything was even created, God is love. In order for God to be love, we should find in God, and in fact do find, a communion of persons: lover (Father), beloved (Son) and bond of love (Holy Spirit).


After the New Testament came into being, the greatest minds of the Church continued grappling with the mystery of the Trinity. St. Augustine of Hippo came up with one of the most helpful ways to understand this mystery, something we call the Psychological Analogy for the Trinity. Augustine’s starting point is how we are built as human beings. Since we are created in God’s image, we can learn about who God is by observing human nature. As human beings, we have two main abilities: thinking and loving. We find that every human being is able to create a mental image of himself or herself. We do this whenever we try to answer the question “who am I”? In answering this question, you create an idea of who you are. What you look like. How you speak. How you act. Though we may not be happy with all its aspects, hopefully on the whole we love this self image. After all, Jesus calls us to “love your neighbour as yourself” (Mark 12:31). We are all, therefore, able to both create a mental image of ourselves and also to love this image. Augustine explains that when we consider God doing the same thing, we better understand how the Trinity arises. When God the Father thinks about Himself, His self-image is so perfect that it is not just an idea but actually a person, God the Son. God the Father, aware of this image of Himself, loves it perfectly. This perfect love is the Holy Spirit. We can therefore understand the Trinity by considering God thinking about and loving Himself.The Son comes about when God the Father thinks about Himself. The Holy Spirit comes about when the Father loves the Son, His perfect self image.


For over 300 years the Church discussed and struggled to comprehend the mystery of the Trinity. During this time, individuals often made mistakes in trying to explain the Trinity. Some would overemphasize the unity of God, neglecting that God is three persons. Others would overemphasize that God is three persons, downplaying the unity of God. Perhaps the greatest challenge to our belief in the Trinity came about in the fourth century. At this time, the teaching of a particular priest from Alexandria named Arius became very popular. In order to protect the fact that God is one, Arius downplayed the Divinity of the Son. Arius claimed the Son was not the same nature as the Father. The Son was the first of all creatures, ranking high above any other created thing. He was worthy of great respect, yet He was not God. This teaching of Arius became very popular and many Bishops believed it. It threatened to tear the Church apart. In order to head off the problem, the Emperor Constantine called a council in order to settle the matter. This council was held in Nicaea in the year 325. There, the Bishops of the Church resoundingly denounced the teaching of Arius, affirming that Jesus was indeed God. If Jesus was not God, His death on the Cross could not save us. The Council of Constantinople in 381 later reaffirmed the Divinity of the Holy Spirit. From these two great councils we derive one of the creeds we say at Mass, often called the Nicene Creed. The language of this creed defends our belief that Jesus is indeed God, one of the persons of the Trinity:
I believe in one Lord Jesus Christ,
the Only Begotten Son of God,
born of the Father before all ages.
God from God, Light from Light,
true God from true God,
begotten, not made, consubstantial with the Father;
through him all things were made.
Thanks to the Councils of Nicaea and Constantinople, our belief that the one God exists in three persons was defended.


We may be tempted to think that the doctrine of the Trinity has no practical application to our life. It is a discussion for Catholic nerds alone. Nothing, however, could be further from the fact. We believe that we are made in the image of the Trinity. Therefore, in order to understand how we are to live as human beings, we must understand the Trinity. Here are just a few of the practical consequences of our belief in the Trinity.
  • The Trinity is our origin and our final destination. We have been created out of the overflow of love in the Trinity. The end goal of our life in union with the Trinity.
  • In our culture we place a great value on independence and on self sufficiency. God however, is not self sufficient nor forever on His own. God is a communion of persons united in a perfect relationship of love. We, therefore, are built to live in relationship with others, being interdependent on them. We are not truly human unless we are in loving relationships with others.
  • In a special way, the family forms an image of the Trinity. Just as the love between Father and Son bring forth the Holy Spirit, the love between husband and wife becomes fruitful in the generation of children.
  • In our spiritual life, we are able to relate in a personal way to each of the three persons of the Trinity, Father, Son and Holy Spirit.

We cannot possibly overstate how central the Trinity is to our life. In addition to being theology nerds for a Sunday, Trinity Sunday is an opportunity to remind ourselves of this truth that we too easily forget. Everyday we make the sign of the Cross, an expression of our belief in a Triune God. Often we do this carelessly. When you make the sign of the Cross today, take a moment to pay reverence to the great mystery of the Holy Trinity.

How we use the Gift of Tongues

Acts 2:1-11, John 20:19-23 (Pentecost, year B)

And they were all filled with the Holy Spiritand began to speak in different tongues,as the Spirit enabled them to proclaim.Now there were devout Jews from every nation under heaven staying in Jerusalem.At this sound, they gathered in a large crowd,but they were confusedbecause each one heard them speaking in his own language.

Whenever I hear this passage, taken from the account of Pentecost in the Acts of the Apostles, I always think of the science fiction story, Hitchhiker’s Guide to the Galaxy, by Douglas Adams. In this novel, the diverse inhabitants of the galaxy are able to communicate with one another thanks to a universal translator called a “babel fish”, which allows the user to understand and speak any language imaginable. The disciples’ ability to speak different languages is one of the most striking details of Pentecost. It is as though the disciples each received a complimentary “babel fish” along with the the gift of the Holy Spirit! Their newfound linguistic prowess had an obvious practical advantages: it aided them in their mission to preach the Gospel to all nations. In addition to its practical utility, the gift of tongues has a deeper meaning which reveals the significance of Pentecost in the history of salvation.


A primary consequence of sin is division among people. In fact, the English word “sin” comes from the German word for sin, “Sünde”.  From this, we also derive the word “sunder”, which means to tear apart or separate. Origen, one of the Church Fathers, explained simply, “where there is division, there is sin”. Disunity among people is marked by a breakdown of communication. The ancient story of the Tower of Babel powerfully illustrates this (Gen. 11:4-9). After the great flood, all humanity was unified in speaking a single language. Their unity was demonstrated by their ability to communicate freely. This all changed when the people decided to build a tower that reached into heaven. In doing this, the people sinned because they tried to put themselves - quite literally - on the same level as God. Because of this sin, the unity of the people was broken. Their languages became confused and they could no longer communicate. In our own lives we experience that sin brings about division. When someone hurts us, we pull back from communion with them. We no longer want to communicate with them as before. Sin causes division.

A primary consequence of the Holy Spirit is unity among people. The Holy Spirit is the perfect bond of love between the Father and the Son in the Trinity. Therefore, wherever the Holy Spirit is there is communion. Unity is achieved when there is affective communication. Some years ago I did some mission work in Tijuana, Mexico. When I first moved there I spoke no Spanish. Because I was unable to communicate with the people I was supposed to serving, I felt cut off from them. My inability to speak their language language meant that I couldn’t enter their world. I tried to be friendly and smile a lot but I could not get to the know the people and they could not get to know me. When my Spanish became good enough to have a proper conversation, everything changed. It was a wonderful experience. Walls were torn down. There was a greater trust and the people opened up to me. I got to know what they were thinking, what was important to them, what gave them hope and what they feared. I learned about their culture in a way that would never have been possible if I had not learned the language. Our ability to communicate brought about unity. Since communion is achieved through communication, it is understandable that one of the first gifts given to the disciples at Pentecost is the gift of tongues, the ability to make themselves understood. At Pentecost, the Holy Spirit overcame the division caused by sin at the Tower of Babel. Humanity was once again able to communicate freely. Unity in any group, whether it be our family or parish community, is a sure sign the Holy Spirit is present.

We live Pentecost in our own lives when we become agents of unity. When we reach out to others and communicate with them, bringing them into communion, we are carrying out the work of the Holy Spirit. Pope Francis does this in a very simple, practical way: he often picks up the phone and calls people in order to enter into closer union with them. When Pope Francis receives a letter from someone who is sick and asking for prayers he often phones them. Recently he called Franco Rabuffi, a sick Italian man, and greeted him with a simple, “Hello, I’m Pope Francis”. Franco hung up on him, thinking it was a prank call. Pope Francis tried again. Again, Franco hung up on the Vicar of Christ. Finally on the third attempt Pope Francis was able to get through to Franco and they talked. Imagine how much closer Franco must have felt to the Pope after their conversation. Communication brings about unity. Pope Francis has phoned the most unexpected people hoping to break down divisions. Some time ago, Pope Francis called up Eugenio Scalfari, a prominent atheist and newspaper editor at his office. Scalfari described the “the telephone call I will never forget as long as live” in this way.
It was half past two in the afternoon. My phone rings and in a somewhat shaky voice my secretary tells me: "I have the Pope on the line. I'll put him through immediately." I was still stunned when I heard the voice of His Holiness on the other end of a the line saying, "Hello, this is Pope Francis." "Hello Your Holiness", I say and then, "I am shocked I did not expect you to call me." "Why so surprised? You wrote me a letter asking to meet me in person. I had the same wish, so I'm calling to fix an appointment. Let me look at my diary: I can't do Wednesday, nor Monday, would Tuesday suit you?" I answer, that's fine. "The time is a little awkward, three in the afternoon, is that okay? Otherwise it'll have to be another day." Your Holiness, the time is fine. "So we agree: Tuesday 24 at 3 o'clock.”
And so they met and talked - an atheist and a Pope who is convinced that unless we seek to bring about unity we are not doing the work of the Holy Spirit.


Sin leads to division. The Holy Spirit, who we have received at Baptism and Confirmation, overcomes separation and builds unity. Communication leads to communion. Let us follow the example of Pope Francis. Sometime soon, pick up the telephone and call somebody who you think you need to be closer to. Phone a sick friend or someone you have been been in an argument with recently or an elderly family member you have lost touch with. In this simple, practical way, we can live Pentecost here and now.

Would it be better if the Ascension never happened?

Mark 16:15-20 (Ascension, year B)


“The time has come for you to start building houses on your own.” This was the last instruction that a young carpenter in training received from his mentor, a master carpenter. These words terrified the young man. For years he had apprenticed alongside the master carpenter, learning from him. His mentor was always there to check his work and answer any question he had about the trade. The young carpenter felt safe working with him. He would have loved to continue working under his mentor for the rest of his career. He felt angry that the master carpenter would no longer allow him to simply assist him, but was forcing him to take full, personal responsibility for projects.


Hesitantly, the young carpenter began building houses on his own. At first it was very difficult. He was unsure of himself. As he progressed through his work day, the young man encountered many challenges and questions he wished he could discuss with his old mentor. This, however, was no longer possible. The master carpenter was always at some other job. The young carpenter was forced to figure things out for himself. He experimented, took risks and showed initiative. He made mistakes, but he found as time went on he was learning and becoming a better carpenter. His skills developed in a new way that would not have been possible had he simply continued assisting his old mentor. Eventually he saw the wisdom of the master carpenter. Had his mentor not forced him to build houses on his own, his growth would have been stunted. Being left on his own was necessary for the young man to develop his full potential as a carpenter. Years passed.  The young man became a master carpenter himself and began apprenticing others. Whenever he saw that a young carpenter in training had learned all he or she could from him he would say: “the time has come for you to start building houses on your own”.



Today we celebrate the Ascension of Jesus. As we heard in the Gospel, at the Ascension Jesus gave us a mission and then left us on our to take the personal responsibility to do it. Understandable, when we think about the Ascension of Jesus we can feel like that young carpenter did when his mentor left him to work on His own.


Before He ascended into heaven, Jesus, the carpenter from Nazareth, didn't ask us to build a house, but a kingdom, the Kingdom of God. He gave us a clear mission: go into the whole world and proclaim the gospel to every creature. We are called to tell everyone the Good News about the love of God made manifest in Jesus who has died to save us. We are called to lead others into a relationship with Jesus. We are called to build up the Kingdom of God by transforming the world so that it is more guided by the values of Christ like love, mercy and humility.


Jesus gave us this mission and then He left us. Here is a question that comes into my mind when I consider the Ascension: would it not have been better for us if Jesus had stayed on earth? It is hard to understand why Jesus had to return to His Father. Imagine if Jesus were still with us as He was after the Resurrection and we could still see Him face to face and speak with Him. Whenever we faced a challenge, either in our personal life or as a community, we could simply call up Jesus in Jerusalem, Rome or wherever He happened to be and He could tell us what to do. What should we do today to ensure the poor are taken care of and no one is hungry? If Jesus had not ascended we could just set up a meeting and He could answer that. Want to know how to obtain lasting peace in the Middle East? You would simply need to get Jesus on the phone. How can we properly care for the environment? Get Jesus on Skype and He’d have a solution. At times we can think it would have been better had the Ascension never happened.


Jesus, however, clearly tells us that it is for our own good that He ascends and leaves us (John 16:7). The young carpenter would never have developed into a master carpenter if his mentor was always around him, answering all his questions and preventing him from making any mistakes. The young carpenter had to take full responsibility for projects of his own before He could develop into a master carpenter. Jesus wants us to become become mature in our faith, developing our full potential as His followers. He wants us to become master Christians and not remain apprentices.  We will make mistakes, but if we are to become an adult follower of Jesus we need to take responsibility for building up the Kingdom on our own.


When He ascends into Heaven, Jesus leaves us on our own and yet He doesn't really leave us on our own. The mission of building up the Kingdom of God is at the same time fully our responsibility and a project which God is in full control of. Here is where comparing us Christians to the young carpenter breaks down. In order for him to grow the young carpenter had to take full responsibility for building houses. The work had to be his alone. For this to happen, the master carpenter had to remove himself from the scene completely. Jesus, however, is not bound by this human limitation.  The gift of the Holy Spirit is how Jesus leaves us on our own and yet doesn't really leave us on our own. Pentecost follows the Ascension.The Holy Spirit is a gentle, guiding, strengthening influence in our life. The Holy Spirit allows us to take full responsibility for the mission Jesus has given. At the same time, the Holy Spirit is fully in control, supporting us, keeping us united and giving efficacy to our actions. The Holy Spirit makes the mission fully our work and fully God’s. In completing Jesus' mission "work like everything depends on you and pray like everything depends on God" (Mother Teresa).


“The time has come for you to start building houses on your own.” . The young carpenter not only listened to these words of his mentor but acted on them. For this reason he grew as a carpenter.  “Go into the whole world and proclaim the gospel to every creature”. Today we have once again listened to these words of Jesus. If we act on these words we will grow as His disciple. If we do not, we will never mature. Have you taken personal responsibility for building the Kingdom of God?
