But many do not teach sound doctrine.

但许多都没有教导纯正的道理。

Lets all stick to the sound doctrine of Christ which we first accepted when we first believed Him.

坚持让所有的声音，我们先接受基督学说当初我们相信他。

Holding fast the faithful word as he hath been taught, that he may be able by sound doctrine both to exhort and to convince the gainsayers.

坚守所教真实的道理，就能将纯正的教训劝化人。又能把争辩的人驳倒了。

Embracing that faithful word which is according to doctrine, that he may be able to exhort in sound doctrine, and to convince the gainsayers.

坚持那合乎教理的真道，好能以健全的道理劝戒并驳斥抗辩的人。

Only through light innate nature can the sound, the color, and so on be gained together, can change go mixed, and can doctrine of the mean of boundary arrive.

只有质素平淡，才能将声、色、文、采等一起接收，才能革去偏杂，而进至兼德之中庸境界。
