Clement of Rome

“ And I am baptized into the Holy Ghost, that is, the Comforter, who wrought in all the saints from the beginning of the world, but was afterwards sent to the apostles by the Father, according to the promise of our Saviour and Lord, Jesus Christ; and after the apostles, to all those that believe in the Holy Catholic Church; into the resurrection of the flesh, and into the remission of sins, and into the kingdom of heaven, and into the life of the world to come. ”

“ He must beforehand purify his heart from all wickedness of disposition, from all spot and wrinkle, and then partake of the holy things; for as the skilfullest husbandman does first purge his ground of the thorns which are grown up therein, and does then sow his wheat, so ought you also to take away all impiety from them, and then to sow the seeds of piety in them, and vouchsafe them baptism. ”

“ Moreover, he adores the only begotten God Himself, after His Father, and for Him, giving Him thanks that He undertook to die for all men by the cross, the type of which He has appointed to be the baptism of regeneration. ”
