The conditions discussed in post #48 seemingly refer to old canon law 2357.2 from 1917:
Lay persons who have committed a public crime of adultery or are publicly living in concubinage, or who have been legally found guilty of other crimes against the sixth commandment of the Decalogue, shall be barred from legitimate ecclesiastical acts until they shall show signs of genuine repentance.
This canon was dropped in the revised Code of 1983 with no new correlate. If c. 2357.2 were current and enforced, many divorced/civilly-remarried couples cohabiting in adultery would have to separate, as the marital commandment dictates. Then, if their original, first marriages were found to be valid, they would have the option of honoring God’s preferential regard for first spouses (cf. Mal. 2), or, at-minimum, of obeying Christ’s marital commandment (1 Cor. 7:10-11)–even contemplating reconciliation at a later date.
Enticements toward second consorts could be greatly diminished if the Church were to actually begin to teach and to promote that in which God delights (vs. man’s lusts). More-importantly, raising Godly offspring (cf. Mal. 2) vs. abusing/creating wounded, children-of-divorce would better serve performing the “one thing” God requires of marrieds, for which all will one day answer.
