The church is an altogether New Testament institution. Nowhere in the Old Testament Scriptures is there said anything about the church, the expression so often used, the Old Testament church, or, the Jewish church is therefore incorrect. It springs from the view that Israel, the seed of Abraham, was the church in the past and that since Israel has rejected Christ, the Christian Church has become Israel and all the promises made to Israel are now being fulfilled in a spiritual way. This theory plays havoc with the Word of God and leads into confusion. The presentday condition of Christendom is to a great extent the result of this erroneous view. Israel is not the church, nor has the church taken the place of Israel. All who believed in Old Testament times were saved by grace, in the same way as believing sinners are saved during this dispensation. They were Saints, as we are Saints. But where is there in any portion of the Scriptures of the Old Testament (so-called) a statement that these Jewish believers formed the church of God, the body and the bride of Christ? Israel was not the church in the past and it is equally impossible that the people Israel in their future day of restoration and blessing can become the church. Israel's calling is earthly; the calling of the church is a heavenly calling. Israel will some day possess the earthly Jerusalem while the church will be in the heavenly Jerusalem. Our Lord mentioned the church for the first time. In the Gospel of Matthew xvi:16-18 we find the following words: "And Simon Peter answered and said, Thou art the Christ, the Son of the living God. And Jesus answered and said unto him, Blessed art thou, Simon Bar-Jona: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven. And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it."
