Origen
Catena Aurea · Johannesevangelium 2
Now when he was in Jerusalem at the passover, in the feast day, many believed in his name, when they saw the miracles which he did. But Jesus did not commit himself unto them, because he knew all men. And needed not that any should testify of man: for he knew what was in man.
(tom. x. c. 28) Or, it was those who believed in His Name, not on Him, to whom Jesus would not commit Himself. They believe on Him, who follow the narrow way which leadeth unto life; they believe in His Name, who only believe the miracles.
