All Saints and All Souls
All Saints' Day is a solemn holy day of the Catholic Church celebrated annually on November 1.
The day is dedicated to the saints of the Church, that is, all those who have attained heaven.
It should not be confused with All Souls' Day, which is observed on November 2, and is dedicated to those who have died but who may not yet have reached heaven.
All Saints' Day was formally started by Pope Boniface IV in 609 AD. He also established All Souls' Day, which follows All Saints.
Although millions, or even billions of people may already be saints, All Saints' Day observances tend to focus on known saints -- that is those recognized in the canon of the saints by the Catholic Church.
Saints who have not been canonized— those who are in Heaven, but whose sainthood is known only to God—have no particular feast day, so in a special way, All Saints Day is their feast.
In English, the traditional name for All Saints Day was All Hallows Day. (A hallow was a saint or holy person.)
The vigil or eve of the feast, October 31, is still commonly known as All Hallows Eve.
Praying for those who have died is a Christian obligation. In the modern world, the need for such prayers has only increased.
The Church devotes the month of November to pray for those who have died, the Holy Souls , and participation in the Mass of All Souls Day is a good way to begin the month.
If you wish, loved ones can be remembered in all the Masses in November, by placing their names in the basket on the altar. Candles at the side altars can also be lit.
