Romans 16:17-18 — Now I beseech you, brethren, mark them which cause divisions and offences contrary to the doctrine which ye have learned; and avoid them.
For they that are such serve not our Lord Jesus Christ, but their own belly; and by good words and fair speeches deceive the hearts of the simple.
turn away — not excommunication, but dissociation
serve not — refuse to serve
own body — own base interest
smooth = insinuating
fair — with the appearance of reasonableness
innocent — not expecting evil. Safety lies in knowledge of, and adherence to the Word of God.
divisions — arguments over doctrine
offenses — stumbling blocks
Don't argue — avoid.
If possible, seek unity and truth. If that's not possible, hold to truth.
1 Thessalonians 3:14 — And if any man obey not our word by this epistle, note that man, and have no company with him, that he may be ashamed.
