Parallel
2 John 1:9
Robinson-Pierpont Byzantine Textform · Berean Standard Bible
Πᾶς ὁ παραβαίνων καὶ μὴ μένων ἐν τῇ διδαχῇ τοῦ χριστοῦ, θεὸν οὐκ ἔχει· ὁ μένων ἐν τῇ διδαχῇ τοῦ χριστοῦ, οὗτος καὶ τὸν πατέρα καὶ τὸν υἱὸν ἔχει.
Anyone who runs ahead without remaining in the teaching of Christ does not have God. Whoever remains in His teaching has both the Father and the Son.
