QWe were told by our parish priest
some years ago when communal penance was accepted, that it wasn’t necessary to elaborate on how many
times the sins were committed, only that one had contrition for his sins.
Also, he said that a general description was
all that was necessary, say for instance, a sin such as impurity could
cover many types of
sin in
that category.
A Under normal circumstances, sins of impurity (which you
mentioned) would have to be confessed more specifically. Impurity embraces
lust (desire), masturbation, fornication, pornography, prostitution, and
adultery. (2nd edition of the Catechism of the Catholic Church, p.564,
2528). Those specific titles can be confessed without going into details.
Some general idea as to numbers should be given as well; e.g., two times a
week, or month, or year, so the confessor can tell whether the sin is
habitual or just a momentary lapse of weakness.
