不要依仗你的门派，你的门派不是所有人都接触到我给你讲的道理，他们不知就无罪，你却是知晓的。

这是你和他们的本质区别。

20倘若他们因认识主救主耶稣基督，得以脱离世上的污秽，后来又在其中被缠住制伏，他们末后的景况，就比先前更不好了。
If they have escaped the corruption of the world by knowing our Lord and Savior Jesus Christ and are again entangled in it and overcome, they are worse off at the end than they were at the beginning.
21他们晓得义路，竟背弃了传给他们的圣命，倒不如不晓得为妙。
It would have been better for them not to have known the way of righteousness, than to have known it and then to turn their backs on the sacred command that was passed on to them.
22俗语说得真不错，狗所吐的，它转过来又吃。猪洗净了，又回到泥里去滚。这话在他们身上正合式。
Of them the proverbs are true: "A dog returns to its vomit," and, "A sow that is washed goes back to her wallowing in the mud."
