The Mother’s words to the daughter about how priests with lawful faculties of absolution, no matter what kind of sinners they themselves are, are able to absolve from sins; the same applies to the sacrament of the Eucharist.
SAINT BRIDGET PATRON SAINT OF EUROPE BOOK 4
The Mother speaks: “Go to him who has the faculty of absolution. No matter how leprous the doorkeeper is, he can still open the door as well as a healthy man, provided he has the keys. It is the same with absolution and the sacrament of the altar. No matter who the minister is, provided he has a lawful faculty of absolution, he can absolve from sins. Therefore, no priest is to be rejected.
However, I would forewarn you about two things. The first is that he will not get what he so longs for in the flesh. The other is that his life will soon be cut short. Just as an ant that carries its load of grain day and night sometimes falls down and dies right when it gets close to the nest, and the grain remains outside it, so too, right when this man has begun to reach the goal of his efforts, he will die and be punished, and his empty efforts will come to naught.”
