John Chrysostom — as excerpted in the Catena Aurea on John 1:41-42

“(Hom. xix. [al. xviii.] 1) The Evangelist docs not mention what Christ said to those who followed Him; but we may infer it from what follows. Andrew declares in few words what he had learnt, discloses the power of that Master Who had persuaded them, and his own previous longings after Him. For this exclamation, We have found, expresses a longing for His coming, turned to exultation, now that He was really come.”
