Bede the Venerable
Catena Aurea · Markusevangelium 9
And he said unto them, Verily I say unto you, That there be some of them that stand here, which shall not taste of death, till they have seen the kingdom of God come with power. And after six days Jesus taketh with him Peter, and James, and John, and leadeth them up into an high mountain apart by themselves: and he was transfigured before them. And his raiment became shining, exceeding white as snow; so as no fuller on earth can white them. And there appeared unto them Elias with Moses: and they were talking with Jesus. And Peter answered and said to Jesus, Master, it is good for us to be here: and let us make three tabernacles; one for thee, and one for Moses, and one for Elias. For he wist not what to say; for they were sore afraid. And there was a cloud that overshadowed them; and a voice came out of the cloud, saying, This is my beloved Son: hear him. And suddenly, when they had looked round about, they saw no man any more, save Jesus only with themselves.
(ubi sup.) If the transfigured humanity of Christ and the society of but two saints seen for a moment, could confer delight to such a degree that Peter would, even by serving them, stay their departure, how great a happiness will it be to enjoy the vision of Deity amidst choirs of Angels for ever? It goes on, For he wist not what to say; although, however, Peter from the stupor of human frailty knew not what to say, still he gives a proof of the feelings which were within him; for the cause of his not knowing what to say, was his forgetting that the kingdom was promised to the Saints by the Lord not in any earthly region, but in heaven; he did not remember that he and his fellow-Apostles were still hemmed in by mortal flesh and could not bear the state of immortal life, to which his soul had already carried him away, because in our Father’s house in heaven, a house made with hands is not needed. But again even up to this time he is pointed at, as an ignorant man, who wishes to make three tabernacles for the Law, the Prophets, and the Gospel, since they in no way can be separated from each other.
