To all this I reply, that these words of the Psalmist were a prophecy of the preaching of the gospel, speaking out of the past into the future with the infallible certainty of prophecy. And although the Apostle, in quoting the said passage of the Psalmist, seems to affirm that already in his time the preaching of the gospel had had its course throughout the world, it is to be understood that he speaks in the sense of the aforesaid prophecy; that the preaching and the voice of the gospel had to run, and not that it had already run throughout the whole of the globe, since his quotation of the said passage of the Psalmist was made at so early a period that the gospel was then preached only in a small part of the northern hemisphere. The passage of the Apostle where he so speaks may be also thus understood: he could not say that the gentiles did not hear the voice or word of the gospel to their conversion, because already it has gone forth from the apostolic seminary for the conversion of all the earth; and in order that it may reach to its boundaries, so that no portion of the gentiles throughout the whole world should remain to which it should not reach, and into which it should not penetrate. Moreover it may be understood in this sense, that he speaks of the gentiles (after the consummation of the preaching of the gospel) as placed at the divine tribunal, and as giving to understand that those who would not be converted should have no remission; and on this point the Apostle puts the following question: “Haply all have not heard the word of the gospel, else if they had heard it would they not have embraced it?” and that they had all heard it is a certain thing, since the sound of the gospel voice has sounded throughout all the earth; so that in all these senses this expression of the Apostle may be understood without opposition in any way to the strictness of its genuine and literal meaning. And if any one should say that the nearest explanation of the passage would be, that the sound of the preaching of the gospel might reach to the ends of the earth in the interval which took place between the time when the Apostles went forth to preach the gospel, after the Redeemer had gone up to heaven, and the time when St. Paul said these words,—the answer is, that although the preaching of the gospel may have travelled far in the said interval, it did not extend over any great part even of the northern hemisphere, as is very manifest; and thus the southern hemisphere still remained, and has remained until now, without the voice of the gospel being preached or sounded in it, always excepting those parts of Africa and Peru which are comprehended therein, but which, when its extent is considered, form a very small part of it. Moreover, the equinoctial line, which is, as it were, the boundary of the two hemispheres, may be understood to represent the ends of the earth, to some parts of which the preaching of the gospel might reach in the said interval.
