yes it was, thats why references to the Trinity and the few references to the divinity of Christ are all in the forms of benedictions and doxologies and hymns and creeds.
Benedictions and doxologies:
The grace of the Lord Jesus Christ, and the Love of God, and the communion of the Holy Spirit, be with you all. Amen(2Cor 13.14)
But ye, beloved, building up yourselves on your most holy faith, praying in the Holy Ghost,Keep yourselves in the love of God, looking for the mercy of our Lord Jesus Christ unto eternal life. And of some have compassion, making a difference: And others save with fear, pulling them out of the fire; hating even the garment spotted by the flesh. Now unto him that is able to keep you from falling, and to present you faultless before the presence of his glory with exceeding joy, To the only wise God our Saviour, be glory and majesty, dominion and power, both now and ever. Amen. (Jude20-25)
5 Whose are the fathers, and of whom as concerning the flesh Christ came, who is over all, God blessed for ever. Amen. (Rom 9.35)... For of him, and through him, and to him, are all things: to whom be glory for ever. Amen.(Rom 11.36)
Which in his times he shall shew, who is the blessed and only Potentate, the King of kings, and Lord of lords; Who only hath immortality, dwelling in the light which no man can approach unto; whom no man hath seen, nor can see: to whom be honour and power everlasting. Amen.(1Tim 6.15-16)
And lead us not into temptation, but deliver us from evil: For thine is the kingdom, and the power, and the glory, for ever. Amen.(Matt 6.13)
Christological Poems and hymns known and recited among the christians:
Who, being in the form of God, thought it not robbery to be equal with God:But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men: And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross. Wherefore God also hath highly exalted him, and given him a name which is above every name: That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth; And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father. (Phil 2.6-11)
It is a faithful saying: For if we be dead with him, we shall also live with him: If we suffer, we shall also reign with him: if we deny him, he also will deny us: If we believe not, yet he abideth faithful: he cannot deny himself.(2Tim 2.11-13)
Creeds:
And without controversy great is the mystery of godliness: God was manifest in the flesh, justified in the Spirit, seen of angels, preached unto the Gentiles, believed on in the world, received up into glory.(1 Tim 3.16)
