I have publicly stated that when I first came here, I was a synergist. I believe I was wrong, now I am a monergist.
I hopefully have apologized on occasion for losing it with people. Sometimes people have wanted me to apologize, but in fact, they were not right about what I said, so I have not. But, if I have been unduly harsh, I have on quite a few occasions, apologized.
Since we are only human, and therefore make mistakes, lose it, or generally don't act with respect, it is incumbent upon us all to admit when we are wrong. I think if everyone did this, the forum would be a much more respectful place. Certainly, we all have room for improvement in this area. Name calling and the like should always be admitted and apologized. As far as theology, well, sometimes people realize another aspect of what they were saying, and might admit they were wrong. I hope!
