There is not much information about his life. He is known as Saint Luke the Evangelist. He wrote a major portion in the New Testament – the Gospel According to Saint Luke and the Acts of the Apostles. Paul refers to him as “our beloved physician”.
Luke appears in Acts during Paul’s second journey, remains at Philippi for several years until Paul returns from his third journey, accompanies Paul to Jerusalem, and remains near him when he is imprisoned in Caesarea. During these two years, Luke had time to seek information and interview persons who had known Jesus. He accompanied Paul on the dangerous journey to Rome where he was a faithful companion.
