Luke 24:13

St. Jerome thinks the Cleophas, one of the two disciples, was a citizen of Emmaus, and that he invited Jesus to take meat in his house. His house was afterwards changed into a church, which the same Father says existed in his time. Some think Cleophas was brother to St. Joseph; others, that he was husband of Mary, sister of the blessed Virgin Mary, and father of St. James the less. Both the Latins and Greeks keep the feast of St. Cleophas, and give him the name of an apostle. Usuard says he was martyred by the Jews. (Calmet)
