'Doctrine of Christ' in the Bible

now it is God who keeps you fix'd in the doctrine of Christ; who has appointed me,

he it is that we preach, exhorting, and instructing men in every part of divine knowledge, that they may all be perfectly acquainted with the doctrine of Christ Jesus.

no renegado that deserts the doctrine of Christ, has any interest in the deity: he that adheres to the doctrine of Christ, has an interest both in the father, and in the son.
