And we all, with unveiled face, beholding the glory of the Lord, are being changed into his likeness from one degree of glory to another; for this comes from the Lord who is the Spirit. (2 Corinthians 3:18).

“This text, too, is an excellent summation of much of this present work, namely, the gradual but inevitable transformation of a generous person that accompanies parallel growth in depth of communion with the indwelling Trinity. They who think that fullness of contemplation is meant to be confined to an elite few do not understand the contents of Sacred Scripture. Nor do they understand the great patristic commentators (e.g., St. Gregory of Nyssa in the fourth century) who join with John and Teresa in writing of this transformation.”

Thomas Dubay, Fire Within: St. Teresa of Avila, St. John of the Cross, and the Gospel—On Prayer (San Francisco: Ignatius Press, 1989), page 11.

My comments: Fr. Dubay is making the point the degrees of glory that St. Paul describes are a growth in depth of prayer, and growth in living the message of the Gospel of Jesus, and that message is Love.
