John Chrysostom
Catena Aurea · Johannesevangelium 2
Then answered the Jews and said unto him, What sign shewest thou unto us, seeing that thou doest these things? Jesus answered and said unto them, Destroy this temple, and in three days I will raise it up. Then said the Jews, Forty and six years was this temple in building, and wilt thou rear it up in three days? But he spake of the temple of his body. When therefore he was risen from the dead, his disciples remembered that he had said this unto them: and they believed the Scripture, and the word which Jesus had said.
(Hom. xxiii. 3) But why does He give them the sign of His resurrection? Because this was the greatest proof that He was not a mere man; shewing, as it did, that He could triumph over death, and in a moment overthrow its long tyranny.
