It’s good to make an examination of conscience every night–I review the commandments.
Along the lines of what dshix said above, here is a passage from St. Alphonsus Liguori:
St. Alphonsus Liguori:
Here it will be well to remark, what is unanimously admitted by all theologians, even of the rigorist school, that persons who have during a considerable period of time been leading a virtuous life, and live habitually in the fear of God, whenever they are in doubt, and are not certain whether they have given consent to a grievous sin, ought to be perfectly assured that they have not lost the Divine grace; for it is morally impossible that the will, confirmed in its good purposes for a considerable lapse of time, should on a sudden undergo so total a change as at once to consent to a mortal sin without clearly knowing it; the reason of it is, that mortal sin is so horrible a monster that it cannot possible enter a soul by which it has long been held in abhorrence, without her being fully aware of it. We have proved this at length in our Moral Theology. [Lib. 6, D. 476.] St. Teresa said: No one is lost without knowing it; and no one is deceived without the will to be deceived. [Life, addit.]
