Irenaeus summarizes how Christ's taking human flesh saves humanity with a statement that closely resembles Romans 5:19, "For as by the disobedience of the one man who was originally moulded from virgin soil, the many were made sinners, and forfeited life; so was it necessary that, by the obedience of one man, who was originally born from a virgin, many should be justified and receive salvation."
Ireneo resume como encarnado Cristo salva a humanidade cunha declaración que se asemella a Romanos 5:19: "Porque, como pola desobediencia dun só home que foi orixinalmente moldeado dun solo virxe moitos se fixeron pecadores e perderon a vida, foi necesario que, pola obediencia dun só home, que foi orixinalmente nacido dunha virxe, moitos sexan xustificados e reciban salvación".
