Sermon for Trinity Sunday

+In the name of the Father and of the Son and of the Holy Spirit. Amen.

At the heart of the mystery of the Trinity is mission. Mission is a technical term, which comes from the Latin mittere meaning “to send”. The Trinitarian mission, then, is God’s sending of Himself. We are reminded once again of this in today’s Gospel reading. The message of salvation was spread by an act of sending in today’s Gospel:

Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you; and lo, I am with you always, to the close of the age.

This act of sending the apostles was preceded both chronologically and logically by the Father’s sending of the Son. “God did not send the Son into the world to condemn the world, but in order that the world might be saved through him.” The word used in that familiar passage from John is the Greek apostello, send out, from which we get the word apostle.

And just as the Father sent, or “apostled” the Son, so did both the Father and the Son together send the Holy Ghost. As Jesus said, and as the Apostle John recorded, “the Counselor, the Holy Spirit, whom the Father will send in my name, he will teach you all things, and bring to your remembrance all that I have said to you.” And again, with regard to his Ascension, Jesus assured the disciples “it is to your advantage that I go away, for if I do not go away, the Counselor will not come to you; but if I go, I will send him to you.”

We know God by His actions, and one of God’s principle activities—as we see upon reflection on the doctrine of the Trinity—is sending, “apostling”. And just as God sent Himself, both as the Son and as the Holy Ghost, so does He send the Body of the Son, the Church, out to do His will. God continues to send each of us into the world to be apostles, heralds of the faith, and we must be sure to heed God’s call. God may be sending some of us into far-flung mission fields. He may be sending some of us into ventures closer to home. In all events, we are an “apostolic” people, a “sent” people. It may be that God’s mission field for some of us is in the home, to be a herald of the Good News to those in our families. Perhaps God is sending others into a mission in our workplaces, or in the places where we conduct our social and leisure activities, or out into the community of Findlay, or, as I said, maybe even to some far-flung mission field. Perhaps the task is simply being a good example of the Christian faith to our neighbours, or perhaps it is engaging in some sort of social ministry, or perhaps it is telling someone we know about how much Jesus means to us. That last one can sometimes be difficult for us polite Episcopalians, but that is God’s call to us. In any event, just as God sent Himself, so is he sending each of us to do something for the sake of the Kingdom. It is our responsibility to listen and discern, through prayer and studying scripture and conversation with our fellow Christians, precisely where God means to send us to do the work of the Kingdom.

Now, keep this truth, that God is a “sending” God, in the back of your minds. We shall return to it. First, though, there is another truth we may glean from the doctrine of the Trinity, namely that God is a “loving” God.

Before we delve into this truth and what it means, there is a common, totally understandable, misconception about the nature of the Trinity which needs to be dispelled. We often think of the persons of the Trinity in terms of a sort of division of labour. That is, we assign a job description, as it were, to each person of the Trinity. Specifically, people sometimes talk about the first person of the Trinity, God the Father, as the Creator; the second person of the Trinity, God the Son, as the Redeemer; and the third person of the Trinity, God the Holy Spirit, as the Sanctifier. This application of job descriptions as alternate names for the persons of the Trinity has become more common in recent decades as a means of avoiding masculine language for God, paricularly in blessings.

Now, whatever one thinks of inclusive language, this particular construction is in fact un-Christian. It is actually a very old mistake, which the Church Fathers called “the heresy of modalism”. The idea that God is triune because God acts in three distinct ways, three “modes”, is not correct. Long-story short, its logical conclusion is that there are three gods acting independently of one another, rather than one God in three persons. You see how this quickly leads us away from the Christian understanding.

To the contrary, since very early times the Church has taught that each action which God performs is an action of the whole of God. That is, each person of the Trinity is involved in any work of God. Think back to the first chapter of Genesis, for example. Certainly, God the Father was involved in creating the world, but we also remember that God breathed over the deep in His act of creation. The breath of God, or ruach elohim, in the Hebrew is the Holy Spirit. Likewise, we learn in the first chapter of Genesis that God created by means of the “Word”, and in John’s Gospel, we learn that that “Word” or “Logos” was none other than the second person of the Trinity, God the Son, who became flesh in Jesus Christ our Lord. So, the whole of God—Father, Son, and Holy Spirit—was active in the creation of the heavens and the earth.

Likewise, the whole of God is active in salvation. It is in the name of the Trinity that Christ demands we be baptized. In the passage in John’s Gospel, which serves in other lectionary years as the Gospel for Trinity Sunday, Jesus tells Nicodemus that one must be “born of the Spirit” and that this is made possible because the Father sent the Son. We are not only saved through the grace of our Lord Jesus Christ, but through the love of God the Father, and the fellowship of the Holy Spirit. In short, the whole Godhead, the Trinity, saves us.

To go even a bit further, not only can we not assign job descriptions to the persons of the Trinity, but the job descriptions themselves—“creator”, “redeemer”, and “sanctifier”—unnecessarily divides the work of God into discrete actions. But, in being redeemed, we become a new creation, the apostle tells us. In the redemption brought about by baptism, we are simultaneously sanctified. One could go on, but the upshot is that God actually, ultimately does one thing. He loves us. Creation, and redemption, and sanctification and everything else we attribute to the hand of the most glorious Trinity is an expression of God’s love. “For God so loved the world…”

And this is ultimately the meaning of the Trinity. The Trinity is not about some real or perceived division of labour. The Trinity is about the nature of love. For love to be love there needs to be an Other. Thus, for us to make any sense of the assertion that God is love, God cannot be singular. As St. Augustine put it, “the Father loves the Son, the Son loves the Father, and the Holy Ghost is the love they share.” Even more compelling than Augustine’s explanation to my mind is that of the Eastern Church Fathers, people like St. Gregory of Nyssa and St. Basil. They said that the mystery of the Trinity is defined by a mutual love in which the distinctions between the persons ceases to be apparent. The three are one because of the love they share is perfect. Perhaps we have felt hints of the blurring of personal distinction. Mutual love between spouses or between parents and children can have this quality. Of course, sin means that our love cannot be made perfect in this life, so all we experience are hints. “Sin has broken us apart” and so we cannot fully love in perfect emulation of the Triune Godhead.

And yet we may come to love better when we abide in the mystery of the Holy Trinity. Listen carefully to these words of the apostle John from his first epistle:

No man has ever seen God; if we love one another, God abides in us and his love is perfected in us. By this we know that we abide in him and he in us, because he has given us of his own Spirit. And we have seen and testify that the Father has sent his Son as the Saviour of the world.

The Holy Trinity is defined by the mutual love its members—Father, Son, and Holy Spirit—have for one another. But, the Trinity is not an exclusive, mutual-admiration society. The Father’s sending of the Son and their mutual spiration, or sending of the Holy Ghost to us means that we have been invited into the love of God, invited to abide in the love that the persons of the Trinity have for each other. We have been given the chance to abide in that love. That is ultimately why we are “sent out” by God. Because God sent himself into the world, and we have been brought in to the loving life of the Trinity, so we too—children of the Father, members of Christ’s body, full of the Spirit—may be Christ sent out into the world and may invite others into this great relationship of perfect love.

+In the name of the one eternal and indivisible God : Father, Son, and Holy Spirit. Amen.
