Romans 14v1-12

Our consciences matter - even if they are wrong - we should listen to them. Paul warns about judging others for either being too weak in their faith ("they have too many hang ups") or strong in their faith ("they can't do that if they're a Christian!"). God is ultimately the judge who we must all appear before. There is no condemnation for those who are in Christ Jesus - being in Christ Jesus shows in our attitude to one another.
