“To ignore the fact that Catholics in public life, for example, who persistently violate the moral law regarding the inviolability of innocent human life or the integrity of the marital union, lead many into confusion or even error regarding the most fundamental teachings of the moral law, in fact, contributes to the confusion and error, redounding to the gravest harm to our brothers and sisters, and, therefore, to the whole nation. The perennial discipline of the Church, for that reason among other reasons, has prohibited the giving of Holy Communion and the granting of a Church funeral to those who persist, after admonition, in the grave violation of the moral law (Code of Canon Law, cann. 915; and 1184, § 1, 31).
