Whereas there can be but one Baptism, they think they can Baptize; they have abandoned the fountain of life, yet promise the life and grace of the waters of salvation. It is not cleansing which men find there, but soiling; their sins are not washed away, but only added to. That being "born again" does not bring forth sons to God but to the Devil. Born of a lie, they cannot inherit the things which Truth has promised; begotten by the faithless, they are deprived of the grace of faith.
CyprianPeter, in showing that the Church is one and that only those who are in the Church can be saved, said: "In the Ark of Noah certain persons, numbering only eight, were saved by water, which Baptism effects in like manner for you" (1 Peter 3:20). He proves and demonstrates that the solitary Ark of Noah was the figure of the One Church. If, at the time of this Baptism of the world anyone could have been saved without having been in the Ark of Noah, then he who is outside the Church could now be brought to life by Baptism.
CyprianThis supernatural bread and this consecrated chalice are for the health and salvation of mankind.
CyprianThe Lord withdraws when He is denied, and what is taken by the undeserving does not avail them unto salvation, since the saving grace is turned into ashes and holiness departs.
CyprianAs to what pertains to the case of infants: You [Fidus] said that they ought not to be baptized within the second or third day after their birth, that the old law of circumcision must be taken into consideration, and that you did not think that one should be baptized and sanctified within the eighth day after his birth. In our council it seemed to us far otherwise. No one agreed to the course which you thought should be taken. Rather, we all judge that the mercy and grace of God ought to be denied to no man born
