John Chrysostom — as excerpted in the Catena Aurea on John 7:25-30

“(Hom. l. 1) Or the ignorance, He here speaks of, is the ignorance of a bad life; as Paul saith, They profess that they know God, but in works they deny Him. (Tit. 1:16) Our Lord’s reproof is twofold: He first published what they were speaking secretly, crying out, in order to put them to shame.”
