Confession & MercyEssentials

Do I need to confess a mortal sin committed before I was baptized?

Confession & Mercy

The short answer

No. Baptism forgave all your prior sins — original and personal — and all punishment for them. Confession is for sins committed after baptism.

Baptism forgives all

By baptism all sins are forgiven, original sin and personal sins, and all punishment for sin; nothing remains to impede entry into God's kingdom (CCC 1263).

Confession is for afterward

Christ instituted penance above all for those who, since baptism, have fallen into grave sin and lost baptismal grace (CCC 1446).
