When a man is born, he is already born with death, because he contracts sin from Adam. [Thus] everyone, even little children, have ‘broken God’s covenant’, not indeed in virtue of any personal action, but in virtue of mankind’s common origin in that single ancestor, in [whose corrupted nature] all have sinned. As infants cannot help being descended from Adam, so they cannot help being touched by the same sin, unless they are set free from its guilt by the baptism of Christ, [the new Adam]. All men for whom Christ died, died in the sin of the first Adam, and all who are baptized into Christ die to sin, [and to that carnal life ruled by it]. No one is born without the intervention of carnal concupiscence, which is inherited from the first Man, who is Adam; and no one is reborn without the intervention of spiritual grace, which is given by the second Man, who is Christ.
