Here is an article on the topic of debating with respects to theological controversies and disagreements. Ever heard of these sentiments:
You are not going to convince anyone by debating.
When Christians argue, the whole Church suffers. They will know we are Christians by our love for each other, not by how well we beat each other up with the bible.
Oh well, seems like quite a lot of Christians need to be a little more thick-skinned nowadays, and follow the commands of Scripture rather than just trying to be 'nice', as if one's 'niceness' primarily determines whether someone will turn to Christ and/or embrace sound doctrine or not. And by the way, this is not promoting being 'nasty for Christ', but that we would not shy away from loving confrontation when it is called for.
