8 But some one says, Was he then not cast out of the hearts of the patriarchs and prophets, and the righteous of olden time? Certainly he was. How, then, is it said, “Now he shall be cast out”? How else can we think of it, but that what was then done in the case of a very few individuals, was now foretold as speedily to take place in many and mighty nations? Just as also that other saying, “For the Spirit was not yet given, because that Jesus was not yet glorified,” may suggest a similar inquiry, and find a similar solution.
For it was not without the Holy Spirit that the prophets predicted the events of the future; nor was it so that the aged Simeon and the widowed Anna knew by the Holy Spirit the infant Lord; and that Zacharias and Elisabeth uttered by the Holy Spirit so many predictions concerning Him, when He was not yet born, but only conceived. But “the Spirit was not yet given;” that is, with that abundance of spiritual grace which enabled those assembled together to speak in every language, and thus announce beforehand in the language of every nation the Church of the future: and so by this spiritual grace it was that nations were gathered into congregations, sins were pardoned far and wide, and thousands of thousands were reconciled unto God.
