▼5:7This passage and its message is certainly consistent with the rest of the letter of John. Now there are various opinions about whether or not the author of the letters of John is the same as the author of the Gospel of John. My opinion is that the style of writing and the vocabulary show a different and later author. The lateness of the authorship of this letter explains how the passage about the Father, Word, and Spirit can have a more developed Trinitarian theology than the Gospel. However, those who claim that the passage is not genuine are ignoring its inherent consistency with the rest of the letter from the same author.(Conte)
