Afterward Christ came, saying, “I am born of the Holy Spirit.” Though it is now easy for the Christians to believe this assertion, at that time it was very difficult. According to the text of the Gospel the Pharisees said, “Is not this the son of Joseph of Nazareth Whom we know? How can He say, therefore, I came down from heaven?”[1]
[1 Cf. John 6:42.]
Briefly, this Man, Who, apparently, and in the eyes of all, was lowly, arose with such great power that He abolished a religion that had lasted fifteen hundred years, at a time when the slightest deviation from it exposed the offender to danger or to death. Moreover, in the days of Christ the morals of the whole world and the condition of the Israelites had become completely confused and corrupted, and Israel had fallen into a state of the utmost degradation, misery and bondage. At one time they had been taken captive by the Chaldeans and Persians; at another time they were reduced to slavery to the Assyrians; then they became the subjects and vassals of the Greeks; and finally they were ruled over and despised by the Romans.
This young Man, Christ, by the help of a supernatural power, abrogated the ancient Mosaic Law, reformed the general morals, and once again laid the foundation of eternal glory for the Israelites. Moreover, He brought to humanity the glad tidings of universal peace, and spread abroad teachings which were not for Israel alone but were for the general happiness of the whole human race.

Those who first strove to do away with Him were the Israelites, His own kindred. To all outward appearances they overcame Him and brought Him into dire distress. At last they crowned Him with the crown of thorns and crucified Him. But Christ, while apparently in the deepest misery and affliction, proclaimed, “This Sun will be resplendent, this Light will shine, My grace will surround the world, and all My enemies will be brought low.” And as He said, so it was; for all the kings of the earth have not been able to withstand Him. Nay, all their standards have been overthrown, while the banner of that Oppressed One has been raised to the zenith.
But this is opposed to all the rules of human reason. Then it becomes clear and evident that this Glorious Being was a true Educator of the world of humanity, and that He was helped and confirmed by divine power
