The Synaxis of the Glorious and All-Praiseworthy Twelve Apostles of Christ appears to be an ancient Feast. The Church honors each of the Twelve Apostles on separate dates during the year, and has established a general commemoration for all of them on the day after the commemoration of the Glorious and First-Ranked among the Apostles Peter and Paul.
The holy, glorious, all-laudable Apostle Andrew the First-called is also commemorated on November 30. He was the brother of Saint Peter (June 29).
For lists of the Apostles’ names, see: Mt.10:2, Mark 3:14, Luke 6:12, Acts 1:13, 26.
