On emerging from his retreat, he began the public promulgation of his doctrines; at first, however, with caution and reserve, and keeping within the lines marked out by John the Baptist. Attracted by the young enthusiast, a select band of followers gathered around him, and while he inspired them with implicit trust, they no doubt inspired him in their turn with higher confidence. The reticence which modesty or hesitation had produced gradually melted away, and he began boldly to put forth pretensions which, while they repelled and scandalized many, drew others into a closer companionship and a more implicit submission. Simon and Andrew, James and John, were the first, or among the first, of his disciples. Eight others joined him at about the same period of his life, their names being Philip, Bartholomew, Matthew, Thomas, James the son of Alpheus, Thaddeus, Simon the Canaanite, and Judas (Mk. iii. 14-19; Mt. x. 1-4). While these formed the inner circle, we must suppose that he had many other admirers and followers, who were either less intimate with him, or less constant in their attendance. And there may even have been others of equal intimacy with the twelve apostles, whose names have not been handed down to us. For all the apostles did not enjoy an equally close and unreserved friendship with their master. Three of their number—Simon, James, and John—stood towards him in an altogether special and peculiar relationship. They are far more prominent than any of the other nine. They were selected to accompany Jesus when others were left behind. They formed an inmost circle within the circle of his more constant companions. Them alone he is said to have distinguished by names of his own invention. On Simon he conferred the name of Peter. To James and John, the sons of Zebedee, he applied the familiar nickname of Boanerges, or sons of thunder, which seems to indicate that they were distinguished by the fervor of their zeal (Mk. iii. 16, 17).
