But I beseech you, brethren, to keep a watch on those who are causing the divisions among you, and are leading others into sin, in defiance of the instruction which you have received; and habitually to shun them.
The doctrines and the line of conduct which I taught you –both what you heard and what you saw in me– hold fast to them; and God who gives peace will be with you.
And you followed the pattern set you by us and by the Master, after you had received the Message amid severe persecution, and yet with the joy which the Holy Spirit gives,
and if any one refuses to obey these our written instructions, mark that man and hold no communication with him–so that he may be made to feel ashamed.
Let no one think slightingly of you because you are a young man; but in speech, conduct, love, faith and purity, be an example for your fellow Christians to imitate.
