Clement of Rome (attributed)

So, then, brethren, if we do the will of our Father God, we shall be members of the first church, the spiritual, — that which was created before sun and moon; but if we shall not do the will of the Lord, we shall come under the Scripture which says, "My house became a den of robbers." [Jeremiah 7:11] So, then, let us elect to belong to the church of life, that we may be saved. I think not that you are ignorant that the living church is the body of Christ (for the Scripture, says, "God created man male and female;" [Genesis 1:27; cf. Ephesians 5:22-23] the male is Christ, the female the church,) and that the Books and the Apostles teach that the church is not of the present, but from the beginning. For it was spiritual, as was also our Jesus, and was made manifest at the end of the days in order to save you. [1 Peter 1:20]
