John 14:10

“Believest thou not that I am in the Father? etc.] This surely is, as it must needs be, and ought to be, an article of your faith, “that I am in the Father”, and the Father in me; phrases which are expressive of the sameness of nature in the Father and the Son; of the Son’s perfect equality with the Father, since the Son is as much in the Father, as the Father is in the Son; and also of the personal distinction there is between them; for nothing with propriety can be said to be in itself.
