Rev 3:9

“"Behold, those from the synagogue of Satan who say that they are Jews and are not, but lie: behold, I will make them come and bow down before your feet, and learn that I have loved you." At that time he promised to the universal church that there will be "one flock and one Shepherd." We should note that it was not only in Philadelphia that there were believers from the synagogue of the Jews, as we find recorded in the Acts of the Apostles.… He said to the second angel, "You have the slander of those who say that they are Jews and are not." Nevertheless, he did not promise that there would be some who would come from them, that is, [fall] at the feet of the body of Christ. We believe that this will happen everywhere, since God will command his church to be gathered from the whole world. Therefore, to the sixth angel, that is the one before the last, he promised what he had indicated to the others without any promise. And so he foretells to the sixth angel what will happen before the final end, that the unbelieving will come as suppliants to the church of God.”

“Behold, I will make those of the synagogue of Satan, who say they are Jews and are not. He promised this to the whole Church at that time, because not only in Philadelphia did they believe from the synagogue of the Jews, as we find in the Acts of the Apostles.”

“Behold, I will bring of the synagogue of Satan, who say they are Jews, and are not, but do lie. Behold, I will make them to come and adore before thy feet. And they shall know that I have loved thee. In this passage is foretold the faith of the Jews, according to this: until the fullness of the Gentiles should come in, and so all Israel should be saved. [Rom. 11:25-26] Now they say they are Jews, but are not, because they have lost on the inside spiritually the name they bear on the outside literally; for the expression of the name of Jews is the confession of Christ. However, when Elijah and Enoch are preaching, they will come to adore before the Church's feet, because they will venerate it by following the examples of its action.”
