All Saints
The feast of All Saints achieved great prominence in the ninth century, in the reign of the Byzantine Emperor, Leo VI “the Wise” (886–911). His wife, Empress Theophano lived a devout life.
After her death, her husband built a church, intending to dedicate it to her. When he was forbidden to do so, he decided to dedicate it to “All Saints,” so that if his wife were in fact one of the righteous, she would also be honoured whenever the feast was celebrated.
According to tradition, it was Leo who expanded the feast from a commemoration of All Martyrs to a general commemoration of All Saints, whether martyrs or not. This Sunday marks the close of the Paschal season. To the normal Sunday services are added special scriptural readings and hymns to all the saints (known and unknown) from the Pentecostarion.
The Western Christian holiday of All Saints Day falls on November 1, followed by All Souls’ Day on November 2, and is a Holy Day of Obligation in the Latin Rite of the Catholic Church.
The feast of All Saints, on its current date, is traced to the foundation by Pope Gregory III (731–741) of an oratory in St. Peter’s for the relics “of the holy apostles and of all saints, martyrs and confessors, of all the just made perfect who are at rest throughout the world”, with the day moved to November 1.
