Augustine of Hippo

It is written in the prophet Isaiah, "My house will be called a house of prayer among all nations." But perhaps the Jews will say that the house of God, that is, the synagogue, is open to all. We will not argue the point, except to say that the circumcised always appeal to the law. For their law is of the manner of Abraham's circumcision. Nothing new is to be seen in what the prophet gives. But if only worthless things can be found, who will say that the prophet is speaking unnecessary and empty words? I do not know whether it is prudent to listen and not to prohibit. For since the Jewish people because of their sins, which took them away from God, were asking requests from idols, they were often rebuked by the prophets. They did not want to walk the road of penitence and return to God; to their shame he signals his house is open to all nations for prayer and that since the Jews have abandoned it, he will put others in their place. For if the nations were always being admitted to the law, as the Jews claim, how was the prophet speaking of the future, unless that signified something other than had already been commanded? For it would not be possible to speak of such things as happening every day, since they were yet to come.
