The Correction of Error
When people earnestly desire to live lives pleasing to God, the readjustment of their views, and the renewal of their lives, begin in this world. Not only does Holy Spirit teach them directly but in the secret chamber of their hearts they are helped by communion with the Saints, who, unseen by them are ever at hand to assist them towards the good.
But, as many Christian believers, as well as non-Christian seekers after truth, die while still holding false and partial views of truth, their views are corrected in the next world, provided that they are not obstinately welded to their opinions, and are willing to learn, because neither in this world, nor in the next, does God, or any servant of His, force a man to believe anything against his will.
