While in Ephesus, Apollos “began to speak boldly in the synagogue.” Among his hearers were Aquila and Priscilla, who, perceiving that he had not yet received the full light of the gospel, “took him unto them, and expounded unto him the way of God more perfectly.” Acts 18:26. Through their teaching he obtained a clearer understanding of the Scriptures and became one of the ablest advocates of the Christian faith. (AA 270.1) MC VC

Apollos was desirous of going on into Achaia, and the brethren at Ephesus “wrote, exhorting the disciples to receive him”(Acts 18:27) as a teacher in full harmony with the church of Christ. He went to Corinth, where, in public labor and from house to house, “he mightily convinced the Jews, ... showing by the Scriptures that Jesus was Christ.” Acts 18:28. Paul had planted the seed of truth; Apollos now watered it. The success that attended Apollos in preaching the gospel led some of the believers to exalt his labors above those of Paul. This comparison of man with man brought into the church a party spirit that threatened to hinder greatly the progress of the gospel. (AA 270.2) MC VC

During the year and a half that Paul had spent in Corinth, he had purposely presented the gospel in its simplicity. “Not with excellency of speech or of wisdom” had he come to the Corinthians; but with fear and trembling, and “in demonstration of the Spirit and of power,” had he declared “the testimony of God,” that their “faith should not stand in the wisdom of men, but in the power of God.” 1 Corinthians 2:1, 4, 5. (AA 270.3) MC VC
