In his proving from the divine Scriptures, experience was expressed. For boldness by itself brings no profit if there is no power, nor does power profit without boldness.
Therefore Paul did not leave Aquila in Ephesus in vain. Perhaps the Spirit arranged this for Apollos, so that he might appear in Corinth with greater power."
One should suppose that Apollos himself considered it better to depart from Ephesus to another place, especially since the Apostle Paul was soon expected to arrive in Ephesus.
But there is an opinion that Priscilla and Aquila, as recent arrivals from Corinth, specifically advised Apollos to go there and continue there the work of evangelization begun by Saint Paul.
They probably thought that Apollos's gift of eloquence would bring the greatest possible fruit there.
"The teachers of Apollos," says Saint John Chrysostom, "having long been under the direct influence of Saint Paul, had learned so well that they became capable of teaching others."
"In order to secure for Apollos a good reception in Corinth at the outset, they, together with the brethren of the Ephesian Church, gave him a letter of recommendation to the Corinthian brethren.
Soon Apollos departed from Ephesus, wholly ready to devote himself to preaching the full teaching about Christ that he had received.
This was especially so because he knew the Scriptures well and was able to explain all the passages that contained prophecies about Jesus Christ as the Messiah."
