“We ought, indeed, to confess all our sins to a priest, that we may receive the body and blood of our Lord Jesus Christ, because whoever does not eat his flesh and drink his blood cannot enter into the kingdom of God. We must also each of us partake of this sacrament worthily, for ‘he who eateth and drinketh unworthily, eateth and drinketh judgment to himself, not discerning the body of the Lord.’” (St. Francis of Assisi, Deacon, Letters of St. Francis)
