sentence1: Whoever transgresses and doesn’t remain in the teaching of Christ doesn’t have God. He who remains in the teaching has both the Father and the Son.
sentence2: Πᾶς ὁ παραβαίνων καὶ μὴ μένων ἐν τῇ διδαχῇ τοῦ Χριστοῦ Θεὸν οὐκ ἔχει· ὁ δὲ μένων ἐν τῇ διδαχῇ τοῦ Χριστοῦ, οὗτος καὶ τὸν Πατέρα καὶ τὸν Υἱὸν ἔχει.
