When is the Archangel Michael's day throughout the year? Why does the church celebrate Michael Archangel monthly?
The Archangel Michael is the captain or leader of angels; and one of the strongest intercessors for humanity. His feast was originally celebrated on the 12th of Paone; then it got to be celebrated on the 12th day of all the Coptic months. During the reign of the righteous Emperor Constantine, Pope Alexandros corrected the misunderstanding of the people who used to offer sacrifices to an idol named Zuhul built by Cleopatra. The pope instructed the people to distribute those sacrifices to the poor. This day was henceforth dedicated to the Archangel Michael.
The Egyptians also originally recognized this day as the tear of Isis, who wept over her slain husband Osiris, god of agriculture and abundance. It was believed that her tear drops raised the measure of the water in the Nile on the eve of the 12th of Paone. The Egyptians abandoned this pagan belief dedicating the 12th day of the Coptic months to the feast of the Archangel Michael, who has intervened and interceded on our behalf throughout time and continues to do so.
