O God, who hast made thyself known to us as Trinity in Unity and Unity in Trinity, in order that we may be informed of thy love and thy majesty: Mercifully grant that we may not be terrified by what thou hast revealed of thy majesty, nor tempted to trespass upon thy mercy by what we know of thy love for us; but that by the power of thy Spirit we may be forever drawn to thee in true adoration and worship; who livest and reignest, one God, world without end.

Keep us, O Lord, from the vain strife of words, and grant us a constant profession of our faith.  Preserve us in the way of truth, so that we may ever hold fast that which we professed when we were baptized into the name of the Father, and of the Son, and of the Holy Ghost, and may give glory to thee, our Creator, Redeemer and Sanctifier, now and for evermore.

But our argument in reply to this is ready and clear. For any one who condemns those who say that the Godhead is one, must necessarily support either those who say that there are more than one, or those who say that there is none. But the inspired teaching does not allow us to say that there are more than one, since, whenever it uses the term, it makes mention of the Godhead in the singular; as ‘In Him dwells all the fullness of the Godhead’ Colossians 2:9 “; and, elsewhere ‘The invisible things of Him from the foundation of the world are clearly seen, being understood by the things that are made, even His eternal power and Godhead Romans 1:20.’ If, then, to extend the number of the Godhead to a multitude belongs to those only who suffer from the plague of polytheistic error, and on the other hand utterly to deny the Godhead would be the doctrine of atheists, what doctrine is that which accuses us for saying that the Godhead is one? But they reveal more clearly the aim of their argument. As regards the Father, they admit the fact that He is God , and that the Son likewise is honoured with the attribute of Godhead; but the Spirit, Who is reckoned with the Father and the Son, they cannot include in their conception of Godhead, but hold that the power of the Godhead, issuing from the Father to the Son, and there halting, separates the nature of the Spirit from the Divine glory. And so, as far as we may in a short space, we have to answer this opinion also.

What, then, is our doctrine? The Lord, in delivering the saving Faith to those who become disciples of the word, joins with the Father and the Son the Holy Spirit also; and we affirm that the union of that which has once been joined is continual; for it is not joined in one thing, and separated in others. But the power of the Spirit, being included with the Father and the Son in the life-giving power, by which our nature is transferred from the corruptible life to immortality, and in many other cases also, as in the conception of “Good,” and “Holy,” and “Eternal,” “Wise,” “Righteous,” “Chief,” “Mighty,” and in fact everywhere, has an inseparable association with them in all the attributes ascribed in a sense of special excellence. And so we consider that it is right to think that that which is joined to the Father and the Son in such sublime and exalted conceptions is not separated from them in any.

Read it carefully and read it all.

‘For many people, the doctrine of the trinity is one of the most baffling areas of Christian theology. How can we think of God as “three persons”? There are many who suspect that this is simply an attempt by theologians to make their subject in accessible to outsiders. Thomas Jefferson (1743-1826), third President of United States of America was severely critical of what he termed, the “incomprehensible jargon of the Trinitarian arithmetic.” Why on earth do we need to speak of God in this convoluted and puzzling way? Might it suggest that theology is thoroughly irrational?

More recently, Christians have become aware of the Islamic critique of the doctrine, which holds that it compromises the unity of God. Many Christians neglected the notion, partly because it was seen as obscure. Karl Rahner remarked that the modern Christians were “almost mere monotheists,” paying lip service to the Trinity in theory, but ignoring it in practice. “We must be willing to admit,” he remarked, “that, should the doctrine of the Trinity have to be dropped as false the major part of religious literature could well remain virtually unchanged.”

Cyril interprets this “breath of life” to be the Holy Spirit, and argues that God’s breathing of the Spirit into the first human demonstrates that we were created to exist in intimacy with God. We were created to partake of the divine nature, to participate in the divine, and so to attain the beauty of likeness with God.

Sin disrupted this intimacy. Cyril describes the fall, not as a descent into depravity and sinfulness, but as a loss of the Holy Spirit. Through the exercise of the freedom God gave us, humankind shrank from intimacy with the divine and so lost the Holy Spirit.

Cyril argues that one of the central purposes of the Incarnation was our recovery of intimacy with God through the Holy Spirit, and it is this recovery that Jesus’ baptism accomplishes. Through the Incarnation, the Son of God made man becomes the Second Adam, and at his baptism, the Second Adam receives the Holy Spirit, not for his own sake, but for the sake of all humanity.

I suspect that people in the 4th century were better equipped than we are to discuss points of theology. But Hilary also recognised, like Wittgenstein 1,600 years later, that words can lead thinkers astray. He took a conciliatory stance towards those who said that the Son was similar to the Father, not the same. Obviously they are not the selfsame person, though the Council of Nicaea declared they are of one substance.

Anyway, Hilary wrote in a separate book, on the Psalms, that humanity finds salvation in Christ alone, Son of God and Son of man. In assuming human nature, he has united himself with every human being: “He has become the flesh of us all.”

This insight might be useful in trying to understand the puzzling question of why Jesus underwent baptism at the hands of John the Baptist. After all, Jesus had no sins to be cleansed from. 

I think Hilary agreed with Ambrose that Jesus was baptised “because he wished, not to be cleansed, but to cleanse the waters, so that they, being purified by the flesh of Christ that knew no sin, might have the power of baptism.”

All that the Father is, we see revealed in the Son; all that is the Son’s is the Father’s also; for the whole Son dwells in the Father, and he has the whole Father dwelling in himself… The Son who exists always in the Father can never be separated from him, nor can the Spirit ever be divided from the Son who through the Spirit works all things. He who receives the Father also receives at the same time the Son and the Spirit. It is impossible to envisage any kind of severance or disjunction between them: One cannot think of the Son apart from the Father, nor divide the Spirit from the Son. There is between the three a sharing and a differentiation that are beyond words and understanding.

The distinction between the persons does not impair the oneness of nature, nor does the shared unity of essence lead to a confusion between the distinctive characteristics of the persons. Do not be surprised that we should speak of the Godhead as being at the same time both unified and differentiated. Using riddles, as it were, we envisage a strange and paradoxical diversity-in-unity and unity-in-diversity.

–Gregory of Nyssa, Gregory of Nyssa’s Mystical Writings, translated and edited by Herbert Mursillo (Crestwood, N.Y.: St. V1adimir’s Seminary Press, 1979).
