Whether the baptism of John was from God?

Objections

Objection 1 : It would seem that the baptism of John was not from God. For nothing sacramental that is from God is named after a mere man: thus the baptism of the New Law is not named after Peter or Paul, but after Christ. But that baptism is named after John, according to Mt. 21:25: "The baptism of John . . . was it from heaven or from men?" Therefore the baptism of John was not from God.
Objection 2 : Further, every doctrine that proceeds from God anew is confirmed by some signs: thus the Lord (Ex. 4) gave Moses the power of working signs; and it is written (Heb. 2:3,4) that our faith "having begun to be declared by the Lord, was confirmed unto us by them that heard Him, God also bearing them witness by signs and wonders." But it is written of John the Baptist (Jn. 10:41) that "John did no sign." Therefore it seems that the baptism wherewith he baptized was not from God.
Objection 3 : Further, those sacraments which are instituted by God are contained in certain precepts of Holy Scripture. But there is no precept of Holy Writ commanding the baptism of John. Therefore it seems that it was not from God.
