'Doctrine' in the Bible

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

But speak thou the things which befit the sound doctrine:

in all things showing thyself an ensample of good works; in thy doctrine'showing uncorruptness, gravity,

not purloining, but showing all good fidelity; that they may adorn the doctrine of God our Saviour in all things.
