Ignatius of Antioch

The priests indeed, and the ministers of the word, are 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 exercises a providence over them all. This is the Way which leads to the Father, the Rock, the Defence, the Key, the Shepherd, the Sacrifice, the Door of knowledge, through which have entered Abraham, and Isaac, and Jacob, Moses and all the company of the prophets, and these pillars of the world, the apostles, and the spouse of Christ, on whose account He poured out His own blood, as her marriage portion, that He might redeem her. All these things tend towards the unity of the one and only true God.
