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.
(e Bed. in Luc.) Or; the raiment of Christ shadows out the saints, of whom Esaias says, With all these shalt than clothe thee as with a garment; (Isa. 49:18.) and they are likened to snow because theyshall be white with virtues, and all the heat of vices shall be put far away from them. It follows, And there appeared unto them Moses and Elias talking with them.
