I believe he said that in order for him to let his wife return, she would have to return to orthodox Catholicism, and abandon her new spiritual beliefs. That is a huge degree of control.
I disagree 100% with this. This, in my opinion, is a boundary. One that LW is entitled to draw if it is important to him. In fact, I think we would all agree that we all have a similar boundaries. For instance, most people would draw the line if their WAS went off to become a member of a cult. Or of a Satan worshipping sect. Or maybe even a group that believed in and held animal sacrifices. So we all have a religious boundary we would draw, and it is up to each individual to draw that. One of the more common ones today is when two atheists are married, and then one finds religion later. Sometimes that is a boundary for the atheistic spouse that they can't tolerate.
So if one of Lone's conditions for future R is that she give up this new age religion and return to their original chosen faith, I do not see how anyone could tell him that is wrong.
Well I am of the opinion that you are both right. It absolutely is control and manipulation to demand someone follows the same religion as you in order to "stay married". But, if that is important to him then it is his right to demand that. Personally I find it highly amusing that people of certain faiths (particularly Christian) are so convinced that theirs is the only "right" one and have so little tolerance for other faiths when Jesus himself detested religion and was a very vocal opponent of religion. So what did people do? Built multiple entire religions around his rebellion against religion, LOL! The most spiritually engaged, peaceful, loving people I've known were not at all religious, but seemed to have the best grasp of how Jesus wanted us to live.
