His Holiness Jesus Christ was an educator of humanity. His teachings were altruistic; His bestowal universal. He taught mankind by the power of the Holy Spirit and not through human agency, for the human power is limited whereas the divine power is illimitable and infinite. The influence and accomplishment of Christ will attest this. Galen the Greek physician and philosopher who lived in the second century A.D., wrote a treatise upon the civilization of nations. He was not a Christian but he has borne testimony that religious beliefs exercise an extraordinary effect upon the problems of civilization. In substance he says: "There are certain people among us, followers of Jesus the Nazarene who was killed in Jerusalem. These people are truly imbued with moral principles which are the envy of philosophers. They believe in God and fear Him. They have hopes in His favors, therefore they shun all unworthy deeds and actions and incline to praiseworthy ethics and morals. Day and night they strive that their deeds may be commendable and that they may contribute to the welfare of humanity; therefore each one of them is virtually a philosopher, for these people have attained unto that which is the essence and purport of philosophy. These people have praiseworthy morals even though they may be illiterate."
