Whether it was fitting that Christ should be baptized?

Objections

Objection 1 : It would seem that it was not fitting for Christ to be baptized. For to be baptized is to be washed. But it was not fitting for Christ to be washed, since there was no uncleanness in Him. Therefore it seems unfitting for Christ to be baptized.
Objection 2 : Further, Christ was circumcised in order to fulfil the law. But baptism was not prescribed by the law. Therefore He should not have been baptized.
Objection 3 : Further, the first mover in every genus is unmoved in regard to that movement; thus the heaven, which is the first cause of alteration, is unalterable. But Christ is the first principle of baptism, according to Jn. 1:33: "He upon whom thou shalt see the Spirit descending and remaining upon Him, He it is that baptizeth." Therefore it was unfitting for Christ to be baptized.
