A saint is often someone who is seen by the Church as a person whose sins are somehow more pleasing in the eyes of God even than other people's virtues are.
A saint is one who folds his or her hands in prayer saying, "I am nothing." But these saints wink at the sky, trusting they'll get a wink in return. If you don't notice this wink, they will have you on your knees the rest of your life, tormented by a sense of your own unworthiness, forever ignorant of God's grace.
And in the meantime, these "saints" suffer a great deal less from their "unworthiness" than they let on.
