TRINITY SUNDAY, 2024
St Mark’s Episcopal Church, Warwick, R. I.
In the year 325 AD, there occurred an event of momentous importance for the subsequent history of the entire Christian Church. Summoned by the Emperor Constantine, 230 bishops from far and wide gathered at the town of Nicaea in Asia Minor—what is today Turkey—about 55 miles southeast of Constantinople or present-day Istanbul.
It was the first but not the last gathering of its kind: an ecumenical Council. In this context, the word ecumenical means “worldwide” or “universal”—a council bringing together bishops or representatives from all the local churches throughout the world. Most of the bishops who actually attended were from the Greek-speaking Eastern half of the Roman Empire. But the Pope sent two representatives from Rome, and the Bishop of Carthage in North Africa was present as well.
Some of the bishops who traveled with their entourages along the Roman roads to Nicaea bore the scars of tortures they’d suffered in the last great persecution under the Emperor Diocletian. Such a gathering would have been unthinkable during the years when Christianity remained an illegal religion.
Before that time, local councils or synods met to consider questions facing the Church in specific regions. But now, following the conversation of Constantine, it was possible for a worldwide ecumenical council to meet with unprecedented authority to make decisions for the entire Catholic Church throughout all lands.
The Council met for two months and issued rulings on a variety of topics great and small, ranging from the date of Easter to ratification of the Church’s four principal metropolitan sees as Rome, Alexandria, Antioch, and Jerusalem.
But the most pressing item on the Council’s agenda was a raging theological dispute that been dividing Christians for the previous twenty years or so. In the Egyptian city of Alexandria, the presbyter Arius had been teaching a doctrine that struck many of his contemporaries as heretical and blasphemous.
Both Arius and his opponents agreed that the Son of God had come down from heaven and taken flesh in the womb of the Virgin Mary. So Jesus was the incarnate Son of God. But Arius insisted that this Son who’d become incarnate in Jesus Christ was not fully divine but rather a created spirit—the highest of God’s creatures to be sure, but nonetheless inferior and subordinate to God the Father, whose divine nature he did not and could not share.
Those who opposed Arius, including his own bishop Alexander of Alexandria, and Alexander’s successor Athanasius, rightly discerned that unless Christ was truly divine as well as truly human, he could not reconcile fallen humanity to God or communicate God’s divine life to humanity. The Council of Nicaea decisively sided with Alexander and Athanasius against Arius.
And to make the Church’s faith absolutely clear, the Council solemnly promulgated the earliest version of what we know today as the Nicene Creed, beginning “We believe in one God, the Father, the Almighty, maker of heaven and earth, of all that is, seen and unseen.”
Then, to refute the Arian heresy, the Nicene Creed went on to affirm that the Son is “God from God, light from light, true God from true God, begotten, not made, of one being with the Father …” That clause represented the first step in the Church’s formal definition of the doctrine of the Holy Trinity as one God in three Persons: co‑equal, co-eternal, and sharing one divine nature.
On Trinity Sunday, we give thanks for the Ecumenical Councils and the Catholic Creeds handed down to us as key components of what’s known as the “deposit of faith.” (The Catholic Creeds, by the way, are normally reckoned as at least the Apostles Creed and the Nicene Creed, with the Athanasian Creed sometimes thrown in for good measure.) A week ago today, we celebrated the Holy Spirit’s descent on the Day of Pentecost. The Councils and Creeds demonstrate the Holy Spirit’s continuing presence and work in the subsequent centuries, teaching the Church and leading her into all truth.
A useful way of thinking about the Creeds is as thumbnail summaries of the teachings of Scripture. As Episcopalians we affirm that the Bible contains the definitive record of God’s revelation. At the end of each reading, the reader says, “The Word of the Lord.” At my ordination to the priesthood, I was required to swear that I believed the Holy Scriptures of the Old and New Testaments to be the Word of God, and to contain all things necessary to salvation.
But the Bible is a vast compilation of writings, spanning many different periods and composed by many human authors in many different literary genres. Left to themselves, different groups of Christians generally come up with widely varying and often mutually contradictory readings of biblical teaching. In other words, Scripture is not self-interpreting. We need an authoritative guide to Scripture’s true meaning. And the Ecumenical Councils and Catholic Creeds supply the guidance we need.
Our celebration of Trinity Sunday invites us to reflect on the Creeds’ place in our life and worship. A key point is that when we say the Creed together, it’s not meant to be a collective expression of our personal faith as individuals. No, what’s really happening is that the universal Church in heaven and on earth is proclaiming its faith, the Catholic faith, and we’re being invited to join in. That way, by repeated participation in this solemn liturgical proclamation, the Holy Spirit gradually leads us into all truth, forming a mature faith capable of transforming our hearts, minds, and wills.
A favorite story of mine recounts how a distinguished Eastern Orthodox bishop and theologian once visited a certain Divinity School in the South to give a lecture on the Nicene Creed. During the question time that followed, one of the seminarians raised his hand and said, “I’m sorry, but I just can’t say the part about Jesus being born of the Virgin Mary. Try as I may, I simply cannot bring myself to believe in the Virgin Birth.”
The bishop smiled compassionately and answered in a gentle voice: “Well, don’t be too hard on yourself. You’re still very young. You really can’t expect to get it all at once. The crucial thing is not to give up, but to keep on saying it, and then someday God will give you this faith when he knows that you’re ready. In the meantime, just remember that what the Divine Liturgy proclaims is not your own personal faith, but the corporate faith of the entire Catholic Church.”
The great gift, the great blessing, of belonging to a Church such as ours where we recite the Creeds regularly in worship, is that we don’t have to keep on reinventing the theological wheel. As we join in professing the Nicene Creed at the Eucharist every Sunday (and ideally the Apostles Creed every day), we’re drawn into a living relationship with the three divine Persons to whom the Creeds point. So, let’s never tire of faithfully reciting the Creeds! For they direct us towards our fulfillment in the glory of loving union with the one God who is a community of three divine Persons bound together in love.
