John Chrysostom — as excerpted in the Catena Aurea on Mark 1:40-45

“(Hom. 25) As if He said, It is not yet time that My works should be preached, I require not thy preaching. By which He teaches us not to seek worldly honour as a reward for our works. It goes on: But go thy way, shew thyself to the chief of the priests. Our Saviour sent him to the priest for the trial of his cure, and that he might not be cast out of the temple, but still be numbered with the people in prayer. He sends him also, that he might fulfil all the parts of the Law, in order to stop the evil-speaking tongue of the Jews. He Himself indeed completed the work, leaving them to try it.”
