The Anglican church is the largest protestant church to celebrate the holy day.Most protestant denominations do not recognize the holiday and disagree with the theology behind it.In other words, when they died, they had not yet attained full sanctification and moral perfection, a requirement for entrance into Heaven.
Purgatory is necessary so that souls can be cleansed and perfected before they enter into heaven. Thus made atonement for the dead that they might be free from sin." Additional references are found in Zechariah, Sirach, and the Gospel of Matthew.
Jewish tradition also reinforces this belief as well as the tradition and teaching of the Church, which has been affirmed throughout history.
However, Morning and Evening Prayer (Lauds and Vespers) for the Dead, in which the people participate, may be said.
In pre-1969 calendars, which some still follow, and in the Anglican Communion, All Souls Day is instead transferred, whenever 2 November falls on a Sunday, to the next day, 3 November, as in 2008.
While 2 November remained the liturgical celebration, in time the entire month of November became associated in the Western Catholic tradition with prayer for the departed; lists of names of those to be remembered being placed in the proximity of the altar on which the sacrifice of the mass is offered.
