I can see what you are saying, but still my concerns would remain for me. The key point here firstly is to remember none of us is perfect in theology, doctrine yet, we all see through a glass darkly, after after the resurrection shall we know as we are know. So a problem is (with this hypothetical situation) that she is totally wrong or has a really wrong view of God, also that her unique way of relating to Him might be different to you causing it to be expressed differently. And I guess this would be extended by you (in this hypothetical scenario) going into the marriage with the intention of convincing her of your views, that you would hope her to be illuminated, and again whether you intend it or not, she would that pressure (and you would either battle when or if those views caused very different views on what decisions my might have to be made in some situations) or due to the pressure from the relationship to prevent conflicts and tension in one way, she just bows to your views, but doesn't ever really accept them. She just stops and lets your views dominate your married life. There would always be a strong danger that she isn't being illuminated or choosing your views freely, but rather just bowing to your views and your will.
That would not really be as I would see it a way to truly respect and love someone, rather if you love someone and you have really different views, then remain as her friend and discuss and relate to her that way, then there is no pressure on that person to change because they are married to you, and if they were ever to come around to seeing your way of things, of God, they would and it would be truly freely chosen, without pressure to change from other sources.
Well that is my take, but I think anymore and this could go around in circles lol, so take it as you will (it's hardly an total, all-wise authoritative statement
just my take on things, only you can know the realities of the situation if you find yourself in one, and what you should do. Just make sure to always act in God's love in such a situation (if it ever arises
and you should be fine
Interesting discussion, thanks
