Apollos, a Jew, born in Alexandria, and a learned man, as was natural coming from that great centre of Greek and Oriental culture, came to Ephesus. He had been baptized by some of John's disciples, either at Alexandria or in Palestine. It may very possibly have been at Alexandria. St. John's doctrines and followers may have spread to Alexandria by that time, as we are expressly informed they had been diffused as far as Ephesus (see ch. xix. 1-4). Apollos, when he came to Ephesus, entered, like St. Paul, into the synagogue, and "spake and taught carefully the things concerning Jesus, knowing only the baptism of John." He knew about Jesus Christ, but with an imperfect knowledge such merely as John himself possessed. This man began to speak boldly in the synagogue on the topic of the Messiah whom John had preached. Aquila and Priscilla were present in the synagogue, heard the disputant, recognised his earnestness and his defects, and then, having taken him, expounded to him the way of God more fully, initiating him into the full mysteries of the faith by baptism into the name of the Father, Son, and Holy Ghost.[185] This incident has an important bearing upon the foundation and development of the Ephesian Church, but it hears more directly still upon the point on which we have been dwelling. Apollos disputed in the synagogues where Aquila and Priscilla heard him, so that they must have been regular worshippers there notwithstanding their Christian profession and their close intercourse with St. Paul for more than eighteen months. After a little time further, Apollos desired to pass over to Greece. The little Christian Church which met at Aquila's house told him of the wonders they had seen and heard in Achaia and of the flourishing state of the Church in Corinth. They gave him letters commendatory to that Church, whither Apollos passed over, and rendered such valuable help that his name a year or two later became one of the watchwords of Corinthian party strife. The way was now prepared for St. Paul's great mission to Ephesus, exceeding in length any mission he had hitherto conducted, surpassing in its duration of three years the time spent even at Corinth itself. His own brief visit of the year before, the visit and work of the Alexandrian Jew, the quiet conversations, the holy lives, the sanctified examples of Aquila and Priscilla, these had done the preliminary work. They had roused expectation, provoked discussion, developed thought. Everything was ready for the great masterful teacher to step upon the ground and complete the work which he had already so auspiciously begun.
