Therefore we are buried with him by baptism into death: that just as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.
All Commentaries on Romans 6:4 Go To Romans 6
Ambrose of Milan
AD 397
Baptism is a likeness of death when you go down into the water, and when you rise again it becomes a likeness of resurrection. Thus, according to the interpretation of the apostle, just as Christ’s resurrection was a regeneration, so the resurrection from the font is also a regeneration. .
