Epistle to the Philadelphians (Long Version)
Chapter 9: The Old Testament is Good: The New Testament is Better
The priests and the ministers of the word are indeed good, but the High Priest is better, to whom the holy of holies has been committed, and who alone has been entrusted with the secrets of God. The ministering powers of God are good. The Comforter is holy, and the Word is holy, the Son of the Father, by whom He made all things and oversees them all. This is the Way which leads to the Father, the Rock, the Defense, the Key, the Shepherd, the Sacrifice, the Door of knowledge, through which Abraham, Isaac, Jacob, Moses, and all the company of the prophets have entered, along with these pillars of the world, the apostles, and the spouse of Christ, for whom He poured out His own blood as her marriage portion, that He might redeem her.
All these things aim towards the unity of the one and only true God.
But the Gospel possesses something transcendent beyond the former dispensation, namely the appearance of our Saviour Jesus Christ, His passion, and the resurrection itself. For those things which the prophets announced, saying, “Until He comes for whom it is reserved, and He shall be the expectation of the Gentiles,” have been fulfilled in the Gospel, [our Lord saying,] “Go and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost.” All then are good together: the law, the prophets, the apostles, the whole company of others that have believed through them—only if we love one another.
