two articles of the 1992 "catechism of the catholic church" address the reception of the sacraments of penance and holy communion by divorced persons who are civilly remarried. article 1650 states, "they cannot receive eucharistic communion as long as this situation persists." article 1650 continues, "reconciliation through the sacrament of penance can be granted only to those who have repented for having violated the sign of the covenant and of fidelity to christ, and who are committed to living in complete continence". article 2390 states that outside of marriage, the sexual act "constitutes a grave sin and excludes one from sacramental communion".
