Titus 3:9-11
Titus 3:9-11 NLT
Do not get involved in foolish discussions about spiritual pedigrees or in quarrels and fights about obedience to Jewish laws. These things are useless and a waste of time. If people are causing divisions among you, give a first and second warning. After that, have nothing more to do with them. For people like that have turned away from the truth, and their own sins condemn them.
