Good catch! And a graphic description was not necessary to further encourage confession.I’d be surprised if homosexuals acts are frequently missed in Confession.
Of course not all Catholics are American, but I did think it odd that Fr Nix in declaring mortal sin for any Catholic neglecting Friday penance should not mention this important exception.Therefore, from this we may conclude that failure to do penance on a Friday outside of Lent is not a mortal sin. In fact, the Bishops protest that it is not a sin at all.
Finally, if your parish priest or confessor doubts any of the above are mortal sins, please tell him I will debate him publicly on the Magisterium in any place, in any forum (his parish, street corner, or on YouTube) at any time he wants.
