Yeah. The thing is that I know people who were abandoned by their spouses and they remained faithful to their vows and they feel that it’s kind of a kick in the teeth to them that they lived all this time, faithful to the Church but now people want to water down the teaching.As to the concerns many have for abandoned spouses, that is certainly a cross.
One woman in my parish was abandoned years ago by her husband and remained faithful to her vows. She is a very holy woman and I can’t imagine her complaining that she can’t remarry or that the Church is denying her mercy.
The problem with these discussions is that people come at them with a false idea of mercy as a kind of “free-for-all” where you don’t have to do anything hard to come back into union with the Church.
