 John 1.1 in English makes it very clear that Jesus is God in the beginning was the word the word was with God and the word was God but it's even more emphatic in the Greek. In the passage we have two nouns the word and God. The word is Lagos and God is Theos. Lagos is the subject, Theos is what's called the predicate nominative. The predicate nominative describes the category of the class or what the subject is. In this case God is what the word is and even more emphasis is added because in the third clause of the passage Theos is shifted to the front to tell us exactly what the word is. The word is God. So if you disagree that Jesus is God then you are wrong in two languages.
