Tertullian

But then how can opposites be gathered together into him by whom they are in short destroyed? Again, what Christ do the following words announce, when the apostle says: "That we should be to the praise of His glory, who first trusted in Christ? " Now who could have first trusted-i.e. previously trusted -in God, before His advent, except the Jews to whom Christ was previously announced, from the beginning? He who was thus foretold, was also foretrusted.
