Stephanas
Stephanas (Greek:Στεφανᾶς, Stephanas, Greek word #4734 in Strong's, "crown" or "crowned") a member of the church at Corinth, whose family were among those the apostle had baptized (1 Cor. 1:16; 16:15, 17) as the “first-fruits of Achaia”.
He is mentioned by St. Paul in I Corinthians 16:17: "I was glad when Stephanas, Fortunatus and Achaicus arrived, because they have supplied what was lacking from you." and therefore Paul urged the church in Corinth to "be in subjection to such men and to everyone who helps in the work and labours" and to "acknowledge such men".
