[Choose Ye This Day]

Harper's Bible Dictionary: "The formal doctrine of the Trinity as it was defined by the great church councils of the fourth and fifth centuries is not to be found in the New Testament.'"

[Westbrook]

1st John 5:7 For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.

In Italian: Perciocchè tre son quelli che testimoniano nel cielo: il Padre, e la Parola, e lo Spirito Santo; e questi tre sono una stessa cosa.

In Portuguese: Porque três são os que testificam no céu: o Pai, a Palavra, e o Espírito Santo; e estes três são um.

In Russian (don't know if cyrillic will display on your browser) :Ибо три свидетельствуют на небе: Отец, Слово и Святый Дух; и Сии три суть едино.

In the original Greek (using Latin alphabet): oti treiv eisin oi marturountev en tw ouranw o pathr o logov kai to agion pneuma kai outoi oi treiv en eisin

And following that, we have 1st John 5:8-10, which includes an admonition.

8 And there are three that bear witness in earth, the Spirit, and the water, and the blood: and these three agree in one.

9 If we receive the witness of men, the witness of God is greater: for this is the witness of God which he hath testified of his Son.

10 He that believeth on the Son of God hath the witness in himself: he that believeth not God hath made him a liar; because he believeth not the record that God gave of his Son.
