“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.”
John 2:22 — Greek Interlinear
Church Fathers on John 2:22
The Jews seeing Jesus thus acting with power, and having heard Him say, Make not My Father’s house a house of merchandise, ask of Him a sign; Then answered the Jews and said to Him, What sign show You to us, seeing that You do these things?
But were signs necessary for His putting a stop to evil practices? Was not the having such zeal for the house of God, the greatest sign of His virtue? They did not however remember the prophecy, but asked for a sign; at once irritated at the loss of their base gains, and wishing to prevent Him from going further. For this dilemma, they thought, would oblige Him either to work miracles, or give up His present course. But He refuses to give them the sign, as He did on a like…
For inasmuch as they sought a sign from our Lord of His right to eject the customary merchandise from the temple, He replied, that that temple signified the temple of His Body, in which was no spot of sin; as if He said, As by My power I purify your inanimate temple from your merchandise and wickedness; so the temple of My Body, of which that is the figure, destroyed by your hands, on the third day I will raise again.
