**OF BAPTISM.**
The last advantage which our faith receives from baptism is its assuring us not only that we are ingrafted into the death and life of Christ, but so united to Christ himself as to be partakers of all his blessings. For he consecrated and sanctified baptism in his own body, that he might have it in common with us as the firmest bond of union and fellowship which he deigned to form with us; and hence Paul proves us to be the sons of God, from the fact that we put on Christ in baptism ( Gal. 3:27 ). Thus we see the fulfilment of our baptism in Christ, whom for this reason we call the proper object of baptism. Hence it is not strange that the apostles are said to have baptised in the name of Christ, though they were enjoined to baptise in the name of the Father and Spirit also ( Acts 8:16 ; 19:5; Mt. 28:19 ). For all the divine gifts held forth in baptism are found in Christ alone. And yet he who baptises into Christ cannot but at the same time invoke the name of the Father and the Spirit. For we are cleansed by his blood, just because our gracious Father, of his incomparable mercy, willing to receive us into favour, appointed him Mediator to effect our reconciliation with himself. Regeneration we obtain from his death and resurrection only, when sanctified by his Spirit we are imbued with a new and spiritual nature. Wherefore we obtain, and in a manner distinctly perceive, in the Father the cause, in the Son the matter, and in the Spirit the effect of our purification and regeneration. Thus first John baptised, and thus afterwards the apostles by the baptism of repentance for the remission of sins, understanding by the term repentance , regeneration, and by the remission of sins, ablution.
