Goodspeed(i)
9 But have nothing to do with foolish controversies, pedigrees, strife, and wrangles about the Law, for they are profitless and futile.
10 If a man is inclined to a sect, after warning him once or twice, have nothing more to do with him.
11 You may be sure that a man of that kind is corrupt and sinful, for his own actions condemn him.
