Remigius of Auxerre
Catena Aurea · Matthäusevangelium 17
And after six days Jesus taketh Peter, James, and John his brother, and bringeth them up into an high mountain apart, And was transfigured before them: and his face did shine as the sun, and his raiment was white as the light. And, behold, there appeared unto them Moses and Elias talking with him. Then answered Peter, and said unto Jesus, Lord, it is good for us to be here: if thou wilt, let us make here three tabernacles; one for thee, and one for Moses, and one for Elias.
When the Lord was about to shew His disciples the glory of His brightness, He led them into the mountain, as it follows, And he took them up into a high mountain apart. Herein teaching, that it is necessary for all who seek to contemplate God, that they should not grovel in weak pleasures, but by love of things above should be ever raising themselves towards heavenly things; and to shew His disciples that they should not look for the glory of the divine brightness in the gulph of the present world, but in the kingdom of the heavenly blessedness. He leads them apart, because the saints are separated from the wicked by their whole soul and devotion of their faith, and shall be utterly separated in the future; or because many are called, but few chosen, It follows, And he was transfigured before them.
