4 But, say they, “how are we to believe that Christ was born of a woman?” I would answer, by the Gospel which has been preached and is still preached to all the world. But these men, blind themselves, and aiming to blind others, seeing not what they ought to see, while they try to shake what ought to be believed, endeavour to obtrude a question on a matter which is now believed through all the earth. For they answer and say: “Do not think to overwhelm us with the authority of the whole world— let us look to Scripture itself, urge not arguments of mere numbers against us, for the seduced multitude favours you.” To this I answer, in the first place, “Does the seduced multitude favour me?” This multitude was once a scantling. Whence grew this multitude, which in this increase was announced so long before? For this which has been seen to increase, is none other than the same which was seen beforehand. I need not have said, it was a scantling; once it was Abraham only. Consider, brethren; it was Abraham alone throughout all the world at that time; throughout the whole world, among all men, and all nations; Abraham alone to whom it was said, “In your seed shall all nations be blessed;” and what he alone believed of his own single person, is exhibited as present now to many in the multitude of his seed. Then it was not seen, and was believed; now it is seen, and it is contested; and what was then said to one man, and was by that one believed, is disputed now by some few, when in many it is made good. He who made His disciples fishers of men, inclosed within His nets every kind of authority. If great numbers are to be believed, what more widely diffused over the whole world than the Church? If the rich are to be believed, let them consider how many rich He has taken; if the poor, let them consider the thousands of poor; if nobles, almost all the nobility are within the Church; if kings, let them see all of them subjected to Christ; if the more eloquent, and wise, and learned, let them see how many orators, and scientific men, and philosophers of this world, have been caught by those fishermen, to be drawn from the depth to salvation; let them think of Him who, coming down to heal by the example of His own humility that great evil of man's soul, pride, “chose the weak things of the world to confound the things which are mighty, and the foolish things of the world to confound the wise” (not the really wise, but who seemed so to be), “and chose the base things of the world, and things which are not, to bring to nought things that are.”
5. “Whatever you may choose to say,” they say, “we find that in the place where we read that Christ was born, the Gospels disagree with one another, and two things which disagree cannot both be true;” for, says one, “when I have proved this disagreement, I may rightly disallow belief in it, or, at least, do you who accept the belief in it, show the agreement.” And what disagreement, I ask, will you prove? “A plain one,” says he, “which none can gainsay.” With what security, brethren, do you hear all this, because you are believers! Attend, dearly beloved, and see what wholesome advice the Apostle gives, who says, “As you have therefore received Christ Jesus our Lord, so walk ye in Him, rooted and built up in Him, and established in the faith;” for with this simple and assured faith ought we to abide steadfastly in Him, that He may Himself open to the faithful what is hidden in Him; for as the same Apostle says, “In Him are hid all the treasures of wisdom and knowledge;” and He does not hide them to refuse them, but to stir up desire for those hidden things. This is the advantage of their secrecy. Honour in Him then what as yet you understand not, and so much the more as the veils which you see are more in number: for the higher in honour any one is, the more veils are suspended in his palace. The veils make that which is kept secret honoured, and to those who honour it, the veils are lifted up; but as for those who mock at the veils, they are driven away from even approaching them. Because then we “turn unto Christ, the veil is taken away.”
