(Loukios): This name is mentioned twice:
(1) In the church at Antioch which sent out Barnabas and Saul as its missionaries were several prophets and teachers, among whom was Lucius of Cyrene (Ac 13:1). He was probably one of those "men of Cyprus and Cyrene, who, when they were come to Antioch, spake unto the Greeks also" (Ac 11:20). It has been suggested that he is the same as Luke, but this is merely conjecture.
(2) "Lucius and Jason and Sosipater, my kinsmen" were among those who joined Paul in saluting the Christians in Rome (Ro 16:21). By "kinsmen" Paul means "Jews" (compare Ro 9:3; 16:11,21). This Lucius may have been the same person as (1), but, as we have no more information about either, we cannot determine this.
