Therein lies the rub.
and yet in another thread where I said I'd go only to a Primitive Baptist church even if it took driving miles and miles as some of my brethren do, the gist of most of the questions is, "did I not feel others who were not PB's were worshiping the same God" or words to that effect.
This is like an unbeliever being yoked to a believer, and vice-versa.
One will most likely speak of the other about what he believes, and that is going to be unfair to the speaker, because he will be accused of trying to proselytize the entire congregation.
So he can either squirm in his seat, or open his mouth, or leave the church.
Get out of that church, evangelist, and leave your wife there if she doesn't want to come with you.
At least, both of you are worshiping the same Jesus, just that both of you think of grace different.
I've seen professing Christians stay married with practicing Catholics, and everything is cool between them.
Or you'll have to admit to yourself, that, yes, I'd like them to see the "light" of Calvinism.
