…how could a man [Moses] who was a stammerer, who had been brought up in the house of Pharaoh, who was known among men as a murderer, and who out of fear had long been a fugitive and a shepherd, establish in the world so mighty a Cause that the wisest philosophers of the earth would be incapable of producing a thousandth part thereof? This is clearly an extraordinary feat.

A man with a stammering tongue can hardly sustain an ordinary conversation, let alone accomplish what He did! No: Were He not assisted by a divine power, He would never have been able to carry out such a mighty task. These are arguments that none can deny. The materialistic thinkers, the Greek philosophers, and the great men of Rome who became renowned in the world were each versed in but one branch of learning. Thus Galen and Hippocrates were celebrated for their skill in medicine, Aristotle in logic and speculative reasoning, and Plato in ethics and divine philosophy. How can a mere shepherd lay the foundation for all these branches of learning? There is no doubt that He was assisted by an extraordinary power.
