Bad choices by my son.

My Lutheran son is dating a Mormon woman. I do not approve of their relationship b ecause our faths are so different and I do believe they are a christaim group. They do not believe in the Trinity of the Father , Son and holy spirit.

How old is your son, may I ask? It would totally depend on if he is an adult... because as an adult I think he will be able to better judge himself if the relationship will last and if they can find a common ground.
If he is still a teenager, then I wouldn't worry too much about it. The majority of teenage relationships do not last long enough to end in marriage. It is likely they would grow apart before that.
If he is in his 20s or older, then it is totally up to him to decide how important the differences are. You can tell him your opinion of course, but in the end he should be the one to decide whether this is the right woman for him.

The bigotry shown in your question is by far some of the worst I have seen in a while.

You have shown such little compassion for your own flesh and blood based on something as trivial as faith. What she believes is in no way, shape, or form, better or worse than what you believe. You both have faith in something you have no proof exists. Learn how to accept that people will not always believe in what you have to believe, and unless you can successfully brain wash your child, you will push him away by forcing him to date someone who follows a specific religion against his will.

Well... exactly like you said.. choice by my son.. it IS his choice.. and he WILL do whatever he wants reguardless of what you tell him.. if you do not like the decisions he is making.. then sit him down and let him know.. but all you can do as a mother is advise your children to help them make the best decisions, but you cannot make them for them.. they have to do it by themselves, and if they fail... they will learn. good luck..

I agree with rockytina. if hes young it may blow over but if he is an adult its more serious. how would you feel in his shoes? would you want to love someone and have them disliked by your family because of religion reasons? she may be a very sweet and honest girl. and you may never know that unless you get to know her. dont let religion judge love let the heart judge it. and as a parent you should stand by your child even if you are uncomfortable with their life choices. if he is happy, be happy with him.

Mormons are not Christ followers...someday (within 50 years) they will be because they use the Bible and God's Word never returns void.
You are right, though, do not be unequally yoked in relationships!
