47 These facts set forth in sanctuary we have put forward, not on the supposition that the greatness of the agent was to be seen in these virtues alone. For however great these things be, how excessively petty and trifling will they be found to be, if it shall be revealed from what realms He has come, of what God He is the minister! But with regard to the acts which were done by Him, they were performed, indeed, not that He might boast Himself into empty ostentation, bat that hardened and unbelieving men might he assured that what was professed was not deceptive, and that they might now learn to imagine, from the beneficence of His works, what a true god was.
At the same time we wish this also to be known, when, as was said, an enumeration of His acts has been given in summary, that Christ was able to do not only those things which He did, but that He could even overcome the decrees of fate. For if, as is evident, and as is agreed by all, infirmities and bodily sufferings, if deafness, deformity, and dumbness, if shrivelling of the sinews and the loss of sight happen to us, and are brought on us by the decrees of fate and if Christ alone has corrected this, has restored and cared man, it is clearer than the sun himself that He was more powerful than the fates are when He has loosened and overpowered those things which were bound with everlasting knots, and fixed by unalterable necessity.
