Expositor's Bible Commentary Commentary Acts 18:8

"And Crispus, the ruler of the synagogue, believed in the Lord with all his house; and many of the Corinthians hearing believed, and were baptized." — Acts 18:8 (ASV)

One of the first to accept Paul’s message at Corinth was Crispus, the leader of the synagogue, who, together with his whole household, “believed in the Lord.” He was certainly one of the most prominent believers, and his conversion must have made a great impact and led to other conversions. Paul lists him first in 1 Corinthians 1:14–16 among the few that he had baptized.
