Well Baptist generally have communion I think every three months. That by the way I is a closed communion also. But Clinton knew what he was doing. There area ton of Catholic in Arkansas so he knew the protocal. I suspect he did it on purpose knowing it would raise a commotion just to be the center of the news cycle
Yes we Baptists have communion, but we call it Lord's Supper. There isn't a set time for us to have it, but only as the Lord said "as oft as you do this." In my church, it is quarterly on a fifth Sunday. It does not have the same meaning as in Catholic churches ; rather, is a memorial "supper". "As often as you do this, do it in rememberance of me." It is a solemn time for the believer to examine their hearts and remember what Jesus has done for us.
Some Baptist Churches have closed communion (only the local body of believers can participate), some "close" communion (other churches that believe like we do, Sister churches have you may participate) and others Open Communion (all believers may participate - usually baptized believers).
Hope this helps.
Clinton's issues as a "Baptist" were a lot deeper than communion though. The likes of he and Carter make me cringe when I think they were part of my denomination.
