This is a good moment to recall and reflect on an event that demonstrates the wonderful apostolic zeal of the early Christians. Scarcely a quarter of a century had passed since Jesus had gone up to heaven and already his fame had spread to many towns and villages. In the city of Ephesus a man arrived, Apollo by name, 'an eloquent man, well grounded in the Scriptures. He had had instruction in the name of the Lord; and, with a spirit full of zeal, used to preach and teach about the life of Jesus, accurately enough, although he knew of no baptism except that of John.'
A glimmer of Christ's light had already filtered into the mind of this man. He had heard about Our Lord and he passed the news on to others. But he still had some way to go. He needed to know more if he was to acquire the fullness of the faith and so come to love Our Lord truly. A Christian couple, Aquila and Priscilla hear him speaking; they are not inactive or indifferent. They do not think: 'This man already knows enough; it's not our business to teach him.' They were souls who were really eager to do apostolate and so they approach Apollo and 'made friends with him, and gave him a fuller explanation of the way of the Lord'.
