Alphonsus Liguori,
Sermons for all the Sundays in the year…
(1882)
“ And, for the consolation of timid and scrupulous souls, I will here state that, according to the common opinion of theologians, when a soul that fears God and hates sin is in doubt whether she gave consent to a bad thought, she is not bound, as long as she is not certain of having given consent, to confess it: for it is then morally certain that she has not consented to it. Had she really fallen into grevious sin she would have no doubt about it; for mortal sin is so horrible a monster, that it is impossible for him who fears God to admit it into the soul without his knowledge. ”
