VII. The Acts of the Penitent

From The Catechism of the Catholic Church

1456
Confession to a priest is an essential part of the sacrament of Penance:
“All mortal sins of which penitents after a diligent self-examination are
conscious must be recounted by them in confession, even if they are most secret
and have been committed against the last two precepts of the Decalogue; for these
sins sometimes wound the soul more grievously and are more dangerous than those
which are committed openly.”⁵⁴
