While I understand what both of you are saying, where I struggle is the concept of Romans 14, where some will view a particular doctrine in such a way that isn't bad, but may not be for everyone. In other words, if somebody does not eat meat in honor of our Lord, then if I eat meat in view of them, it would cause them to stumble not because eating meat is wrong, but neither is not eating meat for each does it unto the Lord, and each is convinced in their own mind.
We had an instance a few years ago at VBS where we wanted to do some christian karaoke in our fellowship hall with the kids, and some had an issue with it because of the "musical instruments". And it wasn't that it was "worship", but more of a perceived tradition. Think on the lines of a Christian going into a tavern, even for all the right reasons. It could be 'percieved' the wrong way. Know I don't like this line of thought, but it does exist.
Now then, I am very outspoken (imagine that :D ) and I challenged it because I wanted to understand the issue, and had I pushed the issue further than I did, I'm sure we would have had our Karaoke. However, for those less versed in our congregation, it would have caused them to stumble. So, with my point made and my view on musical instruments clear, I backed down.
Net Bible Romans 14:22 The faith you have, keep to yourself before God. Blessed is the one who does not judge himself by what he approves.
I know this sounds silly to some, and don't want to make this an issue of karaoke because that's not the issue and over all, I think this issue was very fruitful in dialog, but sometimes it gets tiresome and I'm reminded of how a wife is to submit to her husband, and I've heard handy and lovely talk about how they submit to their husbands even when they are in disagreement, and it made me think of how we sometimes need to submit to our brothers and sisters in Christ sometimes... and it's not always easy.
