The Synaxis (Assemblage) of the Glorious and All-Praiseworthy Twelve Apostles of Christ appears an ancient feast. Holy Church, honouring each of the Twelve Apostles at a separate time of the year, from ancient times established a general commemoration of them on the day following after the commemoration of the Glorious and First-Ranked among the Apostles Peter and Paul (+ c. 67). An account about each of the Apostles is on the day of his individual commemoration: the Apostle Peter (+ c. 67; Comm. 29 June); the Apostle Andrew the First-Called (+ 62, Comm. 30 November); the Apostle James son of Zebedee (+ 44, Comm. 30 April); the Apostle and Evangelist John the Theologian (+ early second century, Comm. 26 September); Apostle Philip (Comm. 14 November); Apostle Bartholomew (Comm. 11 June); Apostle Thomas (Comm. 6 October); Apostle and Evangelist Matthew (+ 60, Comm. 16 November); Apostle James Alphaeus (Comm. 9 October); Apostle Jude, brother of the Lord (+ c. 80, Comm. 19 June); Apostle Simon Zelotes (Comm. 10 May); Apostle Matthias (+ c. 63, Comm. 9 August).
The holy nobleborn emperor Constantine the Great (306-337) built at Constantinople a temple in the name of the holy Twelve Apostles. Directions for the celebrating of this feast are encountered from the fourth century.
