1. Divorce itself is a sin.
That’s right: Divorce is a sin all on its own, whether or not an illicit “remarriage” follows. There has never been a time in Church history when divorce—defined as an attempt to break the marital contract—has been morally permissible.
Jesus himself forbids divorce in Matthew 19:4-6, as does St. Paul in 1 Corinthians 7:10-11.
And we have solid confirmation from the Catechism of the Catholic Church, which states, “Divorce is a grave offense against the natural law” (2384).
It goes on to say that “divorce is immoral also because it introduces disorder into the family and society” and “brings grave harm to the deserted spouse [and] to children traumatized by the separation of their parents and often torn between them” (2385).
2. Remarriage after divorce adds to the sin.
“Remarriage” after divorce (without annulment) is where most Catholics generally believe that the sin comes in. But, in fact, the civil remarriage after the sin of divorce is an additional sin: the deadly sin of adultery.
Jesus is crystal clear in Luke 16:18, and Paul backs him up in Romans 7:2-3.
The Catechism again confirms it for us:
"Contracting a new union, even if it is recognized by civil law, adds to the gravity of the rupture: the remarried spouse is then in a situation of public and permanent adultery" (2384).
So divorce is the first sin, and “remarriage” (that is, adultery) is the second, exacerbating sin.
But wait—doesn’t the Church allow some divorce?
3. Civil divorce may be “tolerated” by the Church in rare cases, but never for the intent to end the marriage.
The Church allows civil divorce only if an innocent spouse needs legal protections that quite literally cannot be obtained by any other means. The Catechism puts it this way:
"If civil divorce remains the only possible way of ensuring certain legal rights, the care of the children, or the protection of inheritance, it can be tolerated and does not constitute a moral offense" (2383).
Why is it not a sin? Because in accessing the legal help according to the strict limits above, the spouse is not intending to end the actual marriage (as opposed to the state-recognized union).
4. Physical separation is allowed for certain grave reasons, but in all cases, the hopeful expectation is for reconciliation.
The Church teaches that in cases of unrepentant adultery or “grave mental or physical danger,” physical separation of spouses is allowed with the bishop’s permission, but always with the hope of reconciliation.
In fact, here is canon law, which is binding on the faithful: “In all cases, when the cause for the separation ceases, conjugal living must be restored” (1153, §§1-2).
This is not new, but universal, reaching back centuries.
