Who is the Apollos mentioned in 1 Corinthians 3?
Apollos is described as an eloquent man who initially knew only the baptism of John. After Priscilla and Aquila expounded the way of God more accurately to him, he mightily convinced the Jews publicly from the Scriptures that Jesus was the Christ, accomplished great things, and later ministered at Corinth with eloquence and scriptural capability.
Les explains that Apollos came knowing only the baptism of John, and Priscilla and Aquila likely took him home for dinner and unloaded on that eloquent man, expounding the way of God more completely or accurately. Then, as Acts 18:28 records, Apollos mightily convinced the Jews publicly, showing by the Scriptures that Jesus was the Christ. Les notes that Apollos accomplished great things, followed in Paul's footsteps, and was now at the congregation in Corinth, holding forth with eloquence and a capability of opening the Scriptures. This is the same man referenced in 1 Corinthians 3.
For while one saith, I am of Paul; and another, I am of Apollos; are ye not carnal?
