“However, I can’t see any alternative. I’m not sure the Church has the authority to OK bigamy. And I’d say this, I think, even if it were myself involved in this situation.”
I think in the end Mrs. Don-o, The only one who can tell tell you that you are in a state of Grace is yourself...
I would argue that if indeed God was part of the marital union that fell apart, it wouldn’t have would it? That’s my thinking anyway.
Regardless of the possible grounds for an annulment, many people do not peruse one because it has the potential to hurt the X and the kids... People who are concerned about others are exactly the ones who deserve to receive the sacraments.
One cannot justify sinning by one's good intentions for that path leads to Hell.
I, as a miserable sinner, could justify any sinful activity of mine and convince myself I deserve to receive the body, blood, soul and divinity of our Lord Jesus Christ, but I would be lying and would end up condemning myself as St. Paul teaches.
This is nearly the atheist argument against God when faced with evil. While the annulment process need to have greater efficiencies... Ignoring the teachings of the Church and of Jesus Christ himself is probably a bad idea.
