There is a famous statement by Pope St John Paul II (or JP2 to his homeys) that the Church must start to breathe with both her lungs once again — that is, East and West. I don’t know the original context of the statement, but it seems to emerge in discussions about the more ‘rational’ approach to the faith in the western tradition and the more ‘mystical’ approach in eastern Christianity. A false dichotomy, to be sure.
Nonetheless, as the chapter about St John of the Cross in Andrew Louth’s The Origins of the Christian Mystical Tradition shows, there are differences in the approach to mysticism found in East and West. Someone such as Vladimir Lossky would probably boil it down to the differences in our approach to the Most Holy and Undivided Trinity.
This may be part of it.
The problem with Lossky, however, is that the opening chapter of The Mystical Theology of the Eastern Church raises a sharp irreconcilability between the two traditions. He argues that our view of the Trinity is, in fact, false — but does so through a misreading of St Thomas Aquinas and thus the whole of western Trinitarian thought.
And here lies my main thought.
Setting aside for the moment the vexed issue of the procession of the Holy Spirit, I think that we need each when we think about the Trinity, precisely because we are in certain respects different. Our foundation is, however, the same. As St Anselm writes:
Latins call these three things persons, Greeks substances. For as we Latins call the one substance in God three persons, so the Greeks call the one person three substances, they meaning here by substance the very same thing that we mean by person, and not differing from us in faith in any way. (On the Incarnation, ch. 16)
Yet if you read Latin Trinitarian theology, we often start with the unity of God — thus Anselm’s Monologion and Proslogion. Greek theology, on the other hand, often starts with the three Persons — thus St Gregory of Nyssa’s That There Are Not Three Gods. Lossky argues that our insistence on the divine unity posits a fourth hypostasis in the Trinity, a fourth thing that is the ground of being of the three Persons. However, and I forget the title of the book that brought this home to me (it was about Aquinas and Bonaventure’s triadology), what we really mean by that unity is all three persons at once. The unity is a conceptual articulation, not a substance of its own.
Rather than arguing us vs them in Trinitarian theology, East-West dialogue should FIRST acknowledge the incomprehensible and unapproachable mystery here. And then we should see what nuances we can gain from each other. And then, perhaps, we can start to breathe with both our lungs.
And as we breathe with both of these lungs, we will be reminded that the Trinity, the persons beyond personality who are a single God yet three persons, is bigger than any of our doctrinal statements (no matter how true those statements are). And so we will seek Him out in prayer and contemplation, questing after the Uncreated Light, the Beatific Vision, the grace of a meeting with God that is theosis.
But as long as we begin in a position of hostility, our ability to love each other will be hampered. And if we cannot love our brethren whom we can see, how can we love God whom we cannot see?
