All Saints’ Day, also known as All Hallows’ Day, the Feast of All Saints the Feast of All Hallows, the Solemnity of All Saints, and Hallowmas, is a Christian solemnity celebrated in honor of all the saints of the Church, whether they are known or unknown.

From the 4th century, feasts commemorating all Christian martyrs were held in various places, on various dates near Easter and Pentecost. In the 9th century, some churches in the British Isles began holding the commemoration of all saints on 1 November, and in the 9th century this was extended to the whole Catholic Church by Pope Gregory IV.

In Western Christianity, it is still celebrated on 1 November by the Roman Catholic Church as well as many Protestant churches, such as the Lutheran, Anglican, and Methodist traditions. The Eastern Orthodox Church and associated Eastern Catholic and Eastern Lutheran churches celebrate it on the first Sunday after Pentecost. The Syro-Malabar Church and the Chaldean Catholic Church, both of which are in communion with Rome, as well as the Church of the East, celebrate All Saints’ Day on the first Friday after Easter Sunday.  In the Coptic Orthodox tradition, All Saints’ Day is on Nayrouz, celebrated on 11 September. The day is the start of the Coptic new year, and of its first month, Thout.

The Christian celebration of All Saints’ Day and All Souls’ Day stems from a belief that there is a powerful spiritual bond between those in heaven (the “Church triumphant“), the living (the “Church militant“), and the “Church penitent” which includes the faithful departed. In Catholic theology, the day commemorates all those who have attained the beatific vision in Heaven. In Methodist theology, All Saints Day revolves around “giving God solemn thanks for the lives and deaths of his saints“, including those who are “famous or obscure”.^[22] As such, individuals throughout the Church Universal are honored, such as Paul the Apostle, Augustine of Hippo and John Wesley, in addition to individuals who have personally led one to faith in Jesus, such as one’s grandmother or friend.
