1 Jean 5:6-8

6οὗτός ἐστιν ὁ ἐλθὼν δι’ ὕδατος καὶ αἵματος, Ἰησοῦς ὁ Χριστός· οὐκ ἐν τῷ ὕδατι μόνον, ἀλλ’ ἐν τῷ ὕδατι καὶ τῷ αἵματι καὶ τὸ Πνεῦμά ἐστι τὸ μαρτυροῦν, ὅτι τὸ Πνεῦμά ἐστιν ἡ ἀλήθεια.

7ὅτι τρεῖς εἰσιν οἱ μαρτυροῦντες εν τῷ οὐρανῷ, ὁ πατήρ, ὁ λόγος, καὶ τὸ Ἅγιον Πνεῦμα· καὶ οὗτοι οἱ τρεῖς ἕν εἰσι.

8καὶ τρεῖς εἰσὶν οἱ μαρτυροῦντες ἐν τῇ γῇ, τὸ Πνεῦμα, καὶ τὸ ὕδωρ, καὶ τὸ αἷμα· καὶ οἱ τρεῖς εἰς τὸ ἕν εἰσιν.
