Origen

And as John was waiting by the river Jordan for those who came to his baptism, and some he drove away, saying, Generation of vipers, but those who confessed their sins he received, so shall the Lord Jesus stand in the fiery stream with the flaming sword, that whoever after the close of this life desires to pass over to Paradise and needs purification, He may baptize him with this laver, and pass him over to paradise, but whoso has not the seal of the former baptisms, him He shall not baptize with the laver of fire.
