I have planted, Apollos watered; but God gave the increase.

To plant is to evangelize and to bring to faith, to water is to baptize with the approved form of words. To forgive sins, however, and to give the Spirit belongs to God alone. We know that the Holy Spirit is given by God without the laying on of hands, and it has happened that an unbaptized person has received the forgiveness of his sins. Was such a person invisibly baptized, considering that he received the gift which belongs to baptism? Commentary on Paul’s Epistles.
