Bl. Columba Marmion on the Transfiguration
"When He tells us that Jesus is His beloved Son, the Father reveals to us His life; and when we believe in this revelation, we participate in the knowledge of God Himself. The Father knows the Son in endless glory; as for us, we know Him in the shadows of faith whilst awaiting the light of eternity. The Father declares that the Babe of Bethlehem, the Youth of Nazareth, the Preacher of Judea, the Victim of Calvary is His Son, His well-beloved Son; our faith is to believe this.
"It is an excellent thing in the spiritual life to have this testimony of the Father ever present, as it were, before the eyes of the heart. Nothing upholds our faith so powerfully. When we read the Gospel, or a Life of our Lord, when we celebrate his mysteries, when we visit Him in the Blessed Sacrament, when we prepare ourselves to receive Him in our hearts in Holy Communion, or when we adore Him after having received Him, in our whole life, in fine, let us try to have these words habitually before us: 'This is My beloved Son, in Whom I am well pleased.'
"And let us then say: Yea, Father, I believe these words, I will repeat them after Thee: this Jesus Who is within me through faith, through Communion, is Thy Son; and because Thou has said it, I believe it; and because I believe it, I adore Thy Son, so as to render Him my homage; and by Him, in Him, so likewise to render to Thee, O Heavenly Father, in union with Thy Spirit, all honour and all glory."
Bl. Columba Marmion (1858 - 1923) was an Irish Benedictine, who became abbot of Maredsous Abbey in Belgium (more here). He was an accomplished theologian and is a good candidate to one day become a Doctor of the Church. This extract has been taken from the ninth edition of one of his spiritual classics, entitled Christ in His mysteries, printed by Sands and Co. (London, 1939), page 238.
