I was almost divorced last year and against my own will, purple urkel knows some of the details, that God it didnt happen, but if it did and some day I got my priests blessing to remarry and I found someone who had a similar life to mine and we had a Christian marriage in the church would that not disqualify me from ever speaking or debating?
I wouldn't say it's a hard rule. I've thought about this type of thing. Some past things I've done are pretty bad and I wouldn't feel right publicly speaking or debating on certain topics. Something about it seems off. Only in person if there is interest from whomever I'm speaking to.
