SAINT DIADOCHOS
“We share in the image of God by virtue of the intellectual activity of our soul; for the body is, as it were, the soul’s dwelling-place. Now as a result of Adam’s fall, not only were the lineaments of the form imprinted on the soul befouled, but our body also became subject to corruption. It was because of this that the holy Logos of God took flesh and, being God, He bestowed on us through His own baptism the water of salvation, so that we might be reborn. We are reborn through water by the action of the holy and life-creating Spirit, so that if we commit ourselves totally to God, we are immediately purified in soul and body by the Holy Spirit who now dwells in us and drives out sin. Since the form imprinted on the soul is single and simple, it is not possible, as some have thought, for two contrary powers to be present in the soul simultaneously. For when through holy baptism divine grace in its infinite love permeates the lineaments of God’s image – thereby renewing in the soul the capacity for attaining the divine likeness – what place is there for the devil? For light has nothing in common with darkness (cf. 2 Cor. 6:14). We who are pursuing the spiritual way believe that the protean serpent is expelled from the shrine of the intellect through the waters of baptism; but we must not be surprised if after baptism we still have wicked as well as good thoughts. For although baptism removes from us the stain resulting from sin, it does not thereby heal the duality of our will immediately, neither does it prevent the demons from attacking us or speaking deceitful words to us. In this way we are led to take up the weapons of righteousness, and to preserve through the power of God what we could not keep safe through the efforts of our soul alone.
