John 5:22

For neither doth the Father judge any man, but he hath given all judgment unto the Son.

This is not a contradiction of John 1:17f; for, in that place, the thing refuted by Christ was the false expectation that the Messiah would execute a military and political judgment against the Gentiles; and, with reference to that kind of judgment, Jesus came not to judge but to save. The judgment in view here is the eternal judgment, which God has made the exclusive province of the Son of God, all judgment having been placed in his hands. Here Christ plainly told his enemies that they were in the presence of the Judge who would judge them in the last day.
