Am I correct in assuming that a Catholic husband who has had a vasectomy cannot receive Communion? If that is true, what is the remedy? Obviously, reversal cannot always be accomplished.
A vasectomy constitutes grave matter. Together with full knowledge of the gravity of the action and full and free consent to the action, a mortal sin is committed. Assuming these conditions were met, the remedy is the same as for any mortal sin: the sacrament of reconciliation, through which a person is restored to a state of grace and may again receive Communion. The Church does not require that a sterilized man attempt to reverse the vasectomy.
