The image of God

78. 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.
