In the beginning was the Word, and the Word was with God, and the Word was God. In the beginning - That is, before any thing was formed - ere God began the great work of creation. This is the meaning of the word in Genesis 1:1, to which the evangelist evidently alludes. This phrase fully proves, in the mouth of an inspired writer, that Jesus Christ was no part of the creation, as he existed when no part of that existed; and that consequently he is no creature, as all created nature was formed by him: for without him was nothing made that is made, John 1:3. Now, as what was before creation must be eternal, and as what gave being to all things, could not have borrowed or derived its being from any thing, therefore Jesus, who was before all things and who made all things, must necessarily be the Eternal God.
Was the Word - Or, existed the Logos. This term should be left untranslated, for the very same reason why the names Jesus and Christ are left untranslated. The first I consider as proper an apellative of the Savior of the world as I do either of the two last. And as it would be highly improper to say, the Deliverer, the Anointed, instead of Jesus Christ, so I deem it improper to say, the Word, instead of the Logos. But as every appellative of the Savior of the world was descriptive of some excellence in his person, nature, or work, so the epithet Λογος, Logos, which signifies a word spoken, speech, eloquence, doctrine, reason, or the faculty of reasoning, is very properly applied to him, who is the true light which lighteth every man who cometh into the world, John 1:9; who is the fountain of all wisdom; who giveth being, life, light, knowledge, and reason, to all men; who is the grand Source of revelation, who has declared God unto mankind; who spake by the prophets, for the testimony of Jesus is the spirit of prophecy, Revelation 19:10; who has illustrated life and immortality by his Gospel, 2 Timothy 1:10; and who has fully made manifest the deep mysteries which lay hidden in the bosom of the invisible God from all eternity, John 1:18.
The apostle does not borrow this mode of speech from the writings of Plato, as some have imagined: he took it from the Scriptures of the Old Testament, and from the subsequent style of the ancient Jews. It is true the Platonists make mention of the Logos in this way: - καθ' ὁν, αει οντα, τα γενομενα εγενετο - by whom, eternally existing, all things were made. But as Plato, Pythagoras, Zeno, and others, traveled among the Jews, and conversed with them, it is reasonable to suppose that they borrowed this, with many others of their most important notions and doctrines, from them.
And the Word was God - Or, God was the Logos: therefore no subordinate being, no second to the Most High, but the supreme eternal Jehovah.
