Romanos 6:4
So likewise in baptism, since it is a likeness of death, without a doubt, when you are immersed and rise again, it becomes a likeness of resurrection. Therefore, according to the interpretation of the apostle Peter, just as that resurrection was a regeneration, so is this resurrection a regeneration. — On the Sacraments, Book 3, Chapter 1
Romanos 6:6
Until, therefore, this price should have been paid for all men which by the shedding of the Lords Blood had to be so paid for the absolution of all, the blood of every man, who, by the Law and solemn custom were to follow the precepts of holy religion, was required. But, since one Lord Christ suffered, seeing that the ransom is now paid for all, there is now no longer any need that the blood of every man one by one should be shed by circumcision, for in the Blood of Christ the circumcision of all has been solemnized, and in His Cross we are all crucified together with Him, and buried in His sepulchre, and planted together in the likeness of His death, that henceforth we should not serve sin: for he that is dead, is free from sin. — Letter 72, To Constantius
Romanos 6:10
In the Scriptures we learn that there are three kinds of death. The first is when we die to sin and live to God. Blessed is that death which, escaping from sin and devoted to God, separates us from what is mortal and consecrates us to him who is immortal. The second death is the departure from this life.… The third death is that of which it is said: "Let the dead bury their dead." — On the Death of Satyrus 2.36
