- Hadrian II (867-872), who declared civil marriages to be valid, and Pius VII (1800-1823), who declared them invalid
2. that Catholics were once forbidden to marry non-Catholics and it has changed recently to where it is allowed
one, are these accustaions true? if so, how is it explained that they do not contradict the idea of infallibility of pope and/or councils? also, does anyone know of any sites that explain these and other such contradictions?
Re 1. As you can see from the dates, there was a controversy going on. The early church didn’t have as much of a detailed marriage teaching resting on two millennia of fathers, doctors, councils and popes as we have.
In fact, marriages were left to secular authorities. If the couple wanted, it could report to a cleric in a church for the marriage to be blessed, but it wasn’t required for validity. The Church still didn’t recognise some forbidden unions and remarriage after divorce. The effect is comparable to what you have today with a dispensation from canonical form - you can go to a civil magistrate (who may be a practicing whatever-ian, believe in polygamy and divorce), take a witness with you (the magistrate makes the second witness per Canon Law, together making two which is the minimum for validity with such a dispensation from form), and it will be a valid and even sacramental marriage.
If a dispensation from canonical form is given to a certain populace in general, they contract valid sacramental marriages before civil magistrates whenever they attempt marriage before one unless it’s invalid for other reasons, such as insufficient number of witnesses - I’ve seen a case where such a marriage somewhere in the former USSR was annulled because the magistrate was the only witness while two are required for the non-canonical form.
I remember it was very hard for me to grasp the idea that the difference between one or two witnesses as prescribed in the Canon Law can make the difference between a sacrament and lack thereof. Of course, the Church is wiser than I am and the judges in ecclesial tribunals are wiser than a simple civil law student, but nonetheless, I would have more peace of mind without reading about such things.
Question to clerics, theologists, canon lawyers etc present: how does it happen that such a tiny little orderly rule in Canon Law decides if God bestows the sacrament or not as the couple attempts to minister it to each other?
Re 2. It’s a discipline thing. In the beginning, there were not enough Christians for one, and it was a plausible goal to attempt to convert a spouse, for another. Later on, the Church decided that it was better for people to stick to fellow Christians or Catholics, but I’m not aware of any absolute ban. Ask your friend when it was in place. Royal marriages with Orthodox and later also Protestant royalty are perfectly documented. Always dispensation was required, so you could say marriage was forbidden without dispensation, but it wasn’t forbidden unconditionally.
