Baptism in summary – The Largely Catechized Life #100

“But if anyone fall away from it, let him again come into it. For just as Christ, the Mercy-seat, does not recede from us or forbid us to come to Him again, even though we sin, so all His treasure and gifts also remain. If​ therefore, we have once in Baptism obtained forgiveness of sin, it will remain every day, as long as we live, that is, as long as we carry the old man about our neck.”
