9 But in respect of the assertion of some concerning those who had been baptized in Samaria, that when the Apostles Peter and John came, only hands were imposed on them, that they might receive the Holy Ghost, yet that they were not re-baptized; we see that that place does not, dearest brother, touch the present case. For they who had believed in Samaria had believed with a true faith; and within, in the Church which is one, and to which alone it is granted to bestow the grace of baptism and to remit sins, had been baptized by Philip the deacon, whom the same apostles had sent. And therefore, because they had obtained a legitimate and ecclesiastical baptism, there was no need that they should be baptized any more, but only that which was needed was performed by Peter and John; viz., that prayer being made for them, and hands being imposed, the Holy Spirit should be invoked and poured out upon them, which now too is done among us, so that they who are baptized in the Church are brought to the prelates of the Church, and by our prayers and by the imposition of hands obtain the Holy Spirit, and are perfected with the Lord's seal.
