But you will exceed all of them. For you will sacrifice the man that clothes me.
This, to my mind, goes against the whole grain of Christian thougth, it is utterly dualistic in its meaning – Christ's prayer was that two become one, as He and his Father are one, in Unity - the relation of Son and Father, man and God, speaks of this very Union and is foundational to Christian theosis, as exemplified in the Resurrection, and explained in detail by St Paul who spoke out expressly against philosophical dualism.
If the death of the man frees the God within, then man and God are always and irrevocably two. The extinction of the one (man), as the document expresses it, denies the reality of Union - one cannot have 'a union of one', rather it is a return of God to God, of the Alone to the Alone, and in so doing denies any purpose, and metaphysically any reality, to the cosmos.
It expresses, on the other hand, the Hellenic notion of an extreme Platonism in which creature and Creator can never be reconciled.
It denies the Resurrection as a concrete reality - which Jesus Himself insisted on proving - and renders it a psychospiritual resurrection only, and not even resurrection, but at best a recovery of one's true or original form.
If nothing else, the Incarnation affirms the reality and essential goodness of creation, by manifesting that good in corporeal terms. If the world was not made good, then Jesus Christ is not its Logos.
This is the meaning of the Transfiguration. Jesus did not shed his skin atop Mount Tabor, He illuminated it from within. At His side stood Moses and Elijah, signifying the Law and the Prophets (according to Maximus - His rainment is Scripture) - the Word of God the Father was inscribed as Law upon two tablets given to Moses. (Two stones symbolise the two halves of the heart, and the atrium and the ventricle within each.) The Word of God the Spirit was upon the tongue of the Prophets - Elijah the exemplar.
And between them Jesus Christ, the Word made Flesh.
If we accept the account according to Judas, then the reality of the Christian Incarnation is denied, and if corporeally denied, then truth becomes myth, the cloak of a truth which cannot manifest itself in this world.
And the notion of 'Union', for man, becomes meaningless.
