Jason. Mennonites are a whole cultural phenomenon. The take a certain view on the nature of man, how communities work, what almost every aspect of life is all about. And however you look at their community it works.
Now it creates a mindset, a way of dealing with the world, that becomes part of who you are. It is like a culture, an emotional language, a way of expressing yourself. I have met some people from a similar background, bretheren, and I went for a number of years to an open bretheren church. These guys only socialise, holiday etc with their own. It is like a closed family.
So what you trigger in him works at many levels. I sincerely do not believe he hates, but you somehow wind each other up terribly. But why does it bother you so much? Do you want something he is not giving you?
You say he has insulted you. How?
I was accused of insulting people because I said I felt the little god theology was heresy. Can christians believe heresy? Yes. Just take the evolution creation debate. One side is definately right, but which one?
So I might regard something as wrong, but I am open to change my mind. Is that insulting someone? For me it is being honest, which Jesus calls me to be. But for some being a christian is just agreeing their view of faith is that same as theirs or one of us is from God and the other not. I tend to think God is very very gracious, and if we saw the truth, we would all fall apart, because no one would stand.
So grace covers a lot of things, and we are commanded to love as Jesus loved. Hey shoot me down, I am just following Jesus......
