VII. The Acts of the Penitent

From The Catechism of the Catholic Church

1457
According
to the Church’s command, “after having attained the age of discretion,
each of the faithful is bound by an obligation faithfully to confess serious
sins at least once a year.”⁵⁶ Anyone who is aware of having
committed a mortal sin must not receive Holy Communion, even if he experiences
deep contrition, without having first received sacramental absolution, unless
he has a grave reason for receiving Communion and there is no possibility of
going to confession.⁵⁷ Children must go to the sacrament of Penance
before receiving Holy Communion for the first time.⁵⁸
