There’s practically no difference. Maybe I used poor wording: you can say “action-consequence”. The adultery is the action, the divorce and dissolution of the marriage is the consequence. Before the adultery they were married, after the adultery (if they choose) their marriage has ended.
From the Protestant perspective, that’s exactly what’s going on: there was a valid marriage; there was adultery; there is a divorce.
From the Catholic perspective, there’s a real difference:
all Catholic marriages which follow the form required by the Church are presumed to be valid. (Remember: that includes sitting down and being interviewed by a priest or deacon, signing an affidavit that attests that you intend what the Church understands marriage to be, and publicly vowing to this same set of things.) Therefore, when a person requests a nullity, he is not saying “the marriage went bad”, or “s/he cheated on me”; he’s saying “this marriage was invalid from the very beginning.”
That’s a huge difference!
(Now, you might reply “but they’re the same thing! Wedding–marriage–end of marriage.” I would respond that you can look at two situations in which a person (for example) gets shot (i.e., one that’s premeditated murder and another that’s an accident), and those are
very different situations, even though the end result might be the same.)
All if not most of these seem absolutely impossible to determine.
They’re really not. A competent tribunal knows how to make the determination for each of them.
Every validly married spouse could validly make these these claims, even truthfully.
Anyone could
lie and make those claims, I’ll grant you that.
However… ‘truthfully’? I don’t buy it. I see that others have addressed your question, so I won’t repeat the defense here.
This doesn’t make it any clearer: just as they could have not fully understood their vows, they could have easily not fully understood the paper they are signing. Anyone can claim that they did not sufficiently understand something before they did it.
Yes, but you also have the priest who interviewed them. If he felt, at the time of the interview, that sufficient maturity or discretion or understanding or developmental competence was lacking, he would stop the process and not allow the wedding. (After all, priests aren’t permitted to celebrate weddings that they know to be invalid.)
This all just seems to make the point further: Catholic annulment is practically Protestant divorce.
They both start with a wedding that’s presumed valid at the time of the ceremony. They both end with a couple who is considered ‘single’ by their church at the end of the process. That’s about all you can say is the same, however.
