Why did Jesus choose the Twelve from amongst the unlearned in Judea? 

Had he chosen them from among the Masters of Israel, learned in their religion and laws—or even such as I was, an educated priest of Egypt—the people to whom they were sent would not have had cause for wonder; but the fact that they were known to be ignorant men (without taking into account their wonder-working powers) was of itself fitted to arouse the attention of the people to the great truths they proclaimed. No—Jesus did not go to learned doctors, but to simple, untaught fishermen. Had he gone even to the artisan class, he might have got some educated, and partially educated, among them. But fishermen! why, he could not have found a more ignorant class of men on the face of the Earth. They might have been able to weave a net, to drag it in the water for fish, and to give a shrewd opinion of the weather, but that was the most they could do. Poor fellows, they were often very unfortunate in their hauls, and their occupation consequently was reckoned a miserably bad one. Ignorant themselves, they were quite unable to teach their children and did not have the wherewithal to pay others to do it, for at that time education was very expensive. But, indeed, they really did not care anything about it. They taught their children what they themselves knew, and that was very little. Such was the class from which he chose his chief apostles. When these men, in the course of time, were endowed with power to speak and write in strange tongues, it might well be looked on as a miracle by their countrymen, for, I tell you, in my day, it was something to be able to write. 

But why confine the number to Twelve?

The Twelve you must look on more as personal attendants, for it was common at that time for all great teachers to have not only their followers, but a few of these selected specially to be in close personal attendance. We were among those whom you would call the Evangelists; those whom the Master sent out in all directions to spread abroad the doctrines he had taught us. 

Were they Mediums?

The Twelve and the Evangelists were more or less gifted with what you call mediumistic powers. That was one reason why they were chosen. He said they were foreordained as Mediums, through whom the Spirit might speak. Such is the fact, and if his followers in your day could but see it as a fact, they might work wonders before the eyes of worldly men. But the gifts possessed by us were of a much higher character than those possessed by Mediums of the present day. Take my own case. I preached to the people in languages I did not know; I healed the sick and cast out devils; I had direct communication with Spirits, speaking audibly to them, and they to me—walking and talking, eating and drinking with them, and beyond all that, I was privileged to foresee future events. Where, in the present day, will you find a Medium so gifted? Indeed, it was often a matter of wonder to me. I have seen myself, with all my acquired knowledge, coming to a strange people, not knowing how to address them, and wondering how I should get on, but the first man I met I saluted him in his own language, for he replied, and I understood what he said. It was often thus—the lions conjured up in my way were very soon driven off. 

O that the nations of Earth would but submit to his easy yoke! All that he asks of men is that they should aspire to higher life—get nearer and ever nearer to God their Father.
