St. Ephrem on Theosis

St. Ephrem the Syrian ca. 306-373

Far more glorious than the body is the soul, and more glorious still than the soul is the spirit, but more hidden than the spirit is the Godhead. At the end the body will put on the beauty of the soul, the soul will put on that of the spirit, while the spirit shall put on the very likeness of God’s majesty.

For bodies shall be raised to the level of souls, and the soul to that of the spirit, while the spirit will be raised to the height of God’s majesty; clinging to both awe and love, it neither circles too high, nor holds back too much, it discerns when to hold back, so that its flight is beneficial. (The Hymns on Paradise, Hymn IX 20-21)
