Now because Peter sought for a material tabernacle, he was covered with the shadow of the cloud, that he might learn that in the resurrection they are to be protected not by the covering of houses, but by the glory of the Holy Ghost.
Wherefore it goes on, “There was a cloud that overshadowed them.”
And the reason why they obtained no answer from the Lord was that they asked unadvisedly; but the Father answered for the Son.
Wherefore there follows, “And a voice came out of the cloud, saying, This is My beloved Son, in whom I am well pleased.”
