Don, I am not seeing the principle in
Romans 14--or
Jude 1:3 for that matter--you claim is there.
Jude's sentiment is regarding "THE FAITH". As far as he was concerned, Biblical Christianity was being endangered. His writing shows people's salvation was at stake.
Are you making the claim, that because local congregations and orgs don't always give certain members the ability to preach and teach due to the differing views these members hold which aren't in line with either, that Biblical Christianity Itself is in danger? That people's salvation is at stake?
