Disciplinary Rubics
If the priest knows that a person who is living a notoriously evil life intends to come to Communion, the priest shall speak to that person privately, and tell him that he may not come to the Holy Table until he has given clear proof of repentance and amendment of life.
The priest shall follow the same procedure with those who have done wrong to their neighbors and are a scandal to the other members of the congregation, not allowing such persons to receive Communion until they have made restitution for the wrong they have done, or have at least promised to do so.
When the priest sees that there is hatred between members of the congregation, he shall speak privately to each of them, telling them that they may not receive Communion until they have forgiven each other. And if the person or persons on one side truly forgive the others and desire and promise to make up for their faults, but those on the other side refuse to forgive, the priest shall allow those who are penitent to come to Communion, but not those who are stubborn.
In all such cases, the priest is required to notify the bishop, within fourteen days at the most, giving the reasons for refusing Communion.
