All Scripture is about Christ, and so also about
the Body of Christ, the Church. All Scripture,
then, is written to and about the Church
as well as for the Church.
But when he, the Spirit of truth, comes, he will guide you into all truth. For he will not speak on his own authority, but will speak whatever he hears, and will tell you what is to come. He will glorify me, because he will receive from me what is mine and will tell it to you. Everything that the Father has is mine; that is why I said the Spirit will receive from me what is mine and will tell it to you. (John 16:13-15)
