22 When therefore he was risen again from the dead, his disciples remembered, that he had said this, and they believed the scripture, and the word that Jesus had said.
Chrysostom: Two things there were in the mean time very far removed from the comprehension of the disciples: one, the resurrection of our Lord’s Body: the other, and the greater mystery, that it was God who dwelt in that Body: as our Lord declares by saying, Destroy this temple, and in three days I will raise it up. And thus it follows, When therefore He had risen from the dead, His disciples remembered that He had said this to them: and they believed the Scripture, and the word which Jesus had said.
Alcuin: Before the resurrection they did not understand the Scriptures, because they had not yet received the Holy Ghost, Who was not yet given, because Jesus was not yet glorified. [John 7:39] But on the day of the resurrection our Lord appeared and opened their meaning to His disciples; that they might understand what was said of Him in the Law and the Prophets. And then they believed the prediction of the Prophets that Christ would rise the third day, and the word which Jesus had spoken to them: Destroy this temple, etc.
Origen: But (in the mystical interpretation) we shall attain to the full measure of faith, at the great resurrection of the whole body of Jesus, i.e. His Church; inasmuch as the faith which is from sight, is very different from that which sees as through a glass darkly.
