John 1:2

“The same was in the beginning with God.] This is a repetition of what is before said, and is made to show the importance of the truths before delivered; namely, the eternity of Christ, his distinct personality, and proper deity; and that the phrase, in the beginning, is to be joined to each of the above sentences; and so proves, not only his eternal existence, but his eternal existence with the Father, and also his eternal deity; and is also made to carry on the thread of the discourse, concerning the word, and not God the Father; and to express, not only his co-existence in nature, but his co-operation in the works of creation next mentioned.”
