1Jn 3:2-3 (King James)

² Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.
³ And every man that hath this hope in him purifieth himself, even as he is pure.

1Jn 3:2-3 (Stephanus 1550)

² ἀγαπητοὶ, νῦν τέκνα θεοῦ ἐσμεν, καὶ οὔπω ἐφανερώθη τί ἐσόμεθα οἴδαμεν δὲ ὅτι ἐὰν φανερωθῇ, ὅμοιοι αὐτῷ ἐσόμεθα, ὅτι ὀψόμεθα αὐτὸν καθώς ἐστιν
³ καὶ πᾶς ὁ ἔχων τὴν ἐλπίδα ταύτην ἐπ᾽ αὐτῷ, ἁγνίζει ἑαυτὸν, καθὼς ἐκεῖνος ἁγνός ἐστιν

1Jn 3:2-3 (Vulgate)

² Carissimi, nunc filii Dei sumus : et nondum apparuit quid erimus. Scimus quoniam cum apparuerit, similes ei erimus : quoniam videbimus eum sicuti est.
³ Et omnis qui habet hanc spem in eo, sanctificat se, sicut et ille sanctus est.
