It’s no secret that an immense number of people today have been divorced and remarried. Given that many of them are at best only vaguely familiar (if at all) with Scripture’s teaching on this issue, it’s important for us to remind ourselves and those we know and care about of what the biblical foundation is for the Catholic Church’s teaching on divorce and remarriage.
Here’s a little primer I wrote that highlights the major biblical passages and pertinent paragraphs from the Catechism that pertain to this subject. [N.B., It does not address the question of those Catholics who, after a divorce, have petitioned for and received a declaration of nullity (i.e., an "annulment"), but rather, focuses on those who, simply divorce their husbands and wives and attempt to remarry or who “live in sin” with another man or woman.] I hope you find it helpful. Please feel free to share it with others.
