Saint of the day 1st November, We Celebrate All saints day
The Solemnity of All Saints is celebrated on the first of November. It was instituted to honour all of the saints, both known and unknown, and, according to Pope Urban IV, to supply any deficiencies in the faithful’s celebration of saints’ feasts during the year.
In the early days of the Church, the Christians were accustomed to solemnize the anniversary of a martyr’s death for Christ at the place of martyrdom. In the fourth century, neighbouring dioceses began to interchange feasts, to transfer relics, to divide them, and to join in a common feast; as is shown by the invitation of Saint Basil of Caesarea (397) to the bishops of the province of Pontus. Frequently groups of martyrs suffered on the same day, which naturally led to a joint commemoration.
In the persecution of Diocletian, the number of martyrs became so great that a separate day could not be assigned to each, but the Church, feeling that every martyr should be venerated, appointed a common day for all. The first trace of this we find is in Antioch on the Sunday after Pentecost. We also find mention of a common day in a sermon of Saint Ephrem the Syrian (373), and in the 74th homily of Saint John Chrysostom (407).
At first only martyrs and Saint John the Baptist were honoured by a special day in the Liturgical Calendar. Other saints were added gradually, and increased in number when a regular process of canonization was established.
Still, as early as 411 there is in the Chaldean Calendar a “Commemoratio Confessorum” for the Friday after Easter. In the west, Pope Boniface IV on May 13, 609 or 610, consecrated the Pantheon in Rome to the Blessed Virgin and all the martyrs, ordering an anniversary. Gregory III (731-741) consecrated a chapel in the Basilica of Saint Peter to all the saints and fixed the anniversary for November 1.
A basilica of the Apostles already existed in Rome, and its dedication was annually remembered on May 1. Gregory IV (827-844) extended the celebration on November 1 to the entire Church. The vigil seems to have been held as early as the feast itself. The octave was added by Sixtus IV (1471-84).
