1 Timothy 3:9
Holding the mystery of the faith in a pure conscience.
1 Timothy 1:19
Holding faith, and a good conscience; which some having put away concerning faith have made it shipwreck:
1 Timothy 1:5

1 Timothy 3:16
And without doubt great is the mystery of godliness: God was manifest in the flesh, justified in the Spirit, seen of angels, preached unto the Gentiles, believed on in the world, received up into glory.
2 John 1:9-10
Whoever goes beyond, and abides not in the doctrine of Christ, has not God. He that abides in the doctrine of Christ, he has both the Father and the Son.
