The Spiritual Exercises of St. Ignatius of Loyola, [1914], at sacred-texts.com
First. The first: Though whoever goes to Confession every year is not obliged to make a General Confession, by making it there is greater profit and merit, because of the greater actual sorrow for all the sins and wickedness of his whole life.
Second. The second: In the Spiritual Exercises, sins and their malice are understood more intimately, than in the time when one was not so giving himself to interior things. Gaining now more knowledge of and sorrow for them, he will have greater profit and merit than he had before.
Third. The third is: In consequence, having made a better Confession and being better disposed, one finds himself in condition and prepared to receive the Blessed Sacrament: the reception of which is an aid not only not to fall into sin, but also to preserve the increase of grace.
This General Confession will be best made immediately after the Exercises of the First Week.
