The holy, glorious, all-laudable Apostle Junia of the Seventy is commemorated by the Church on May 17 with Apostle Andronicus, and on January 4 with the Seventy. The Seventy Apostles were chosen and sent forth to preach by Christ (Luke 10:1).
Ss. Junia and Andronicus were relatives of the holy Apostle Paul. St Paul mentions them an Epistle: Salute Andronicus and Junia, my kinsmen and fellow prisoners, who are of note among the Apostles, who also were in Christ, before me (Romans 16:7). The service in honor of these saints states that they suffered martyrdom for Christ.
