We'll, I am asking if two non-Catholic Christian people divorce and remarry, because of adultery of one of the spouses (they believe this is permissible), are they living in sin since they don't believe in annulments? Is it a valid remarriage or not?
The Catholic Church doesn't recognize civil divorce and remarriage. The assumption is that the first marriage is valid unless proven otherwise. The way we show it not to be valid is to submit it to a Tribunal for their judgment.
Perhaps if they were Catholic and believed in the annulment process and qualified for the annulment based on the adultery and or? (not sure if adultery alone qualifies) in combination of other things, they would have gotten the annulment.
Adultery is not itself a basis for an annulment. "Annulment" is actually not the right term since the Church does not annul a valid marriage. The couple would seek a declaration of nullity -- in other words, a judgment that a valid marriage never took place. The Tribunal looks at the situation at the time of the marriage. Adultery later in the marriage might be an indication that the adulterous spouse never intended to be faithful, so it might play a part.
I am just trying to find out if Christian brothers and sisters are living in mortal sin and don't even know it. Or perhaps, before God the first "marriage" never took place in the first place and is somehow annulled without even ever going through the process or having to believed in the process?
They might be in an objectively sinful situation, but they can't commit a mortal sin without knowing it.
The requirements for committing a mortal sin are grave matter, full knowledge, and deliberate consent (see the Catechism 1857).
