The F.O.G*

[9] Anyone who runs ahead and doesn't continue in the teaching about the Messiah doesn't have God. But whoever continues in His teaching has both the Father and the Son.

However, anyone who remains in this teaching has both the Father and the Son.

The F.O.G Paraphrase

every one who is transgressing, and is not remaining in the teaching of the Christ, hath not God; he who is remaining in the teaching of the Christ, this one hath both the Father and the Son;
