We all have to be careful. We can preach the right things the wrong way, preach wrong things the right way(usually because of ignorance), as well as preach wrong things the wrong way.
The Bible teaches to expose false teachers/preachers, but if we cause more harm than good with wrong motives & attitudes, we are no better than they are.
We are to 'build up' others in the faith, & expose wrongdoing for the safety of the flock.
Are we "having compassion, making a difference'? Are our words seasoned with grace?
It makes no difference which side we are on if our motives are corrupt.
I see this in CC all the time. Every large conflict is full of it.
