Today, in particular, should not be a day of sadness. All Souls’ Day is for remembering our loved ones who are in Heaven.

ORIGIN OF ALL SOULS’ DAY

All Souls’ Day is the day for the celebration of the eternal life of dear departed ones. It is the Day of Love, because to love is to feel that the other person will never die.

It is a celebration of this eternal life that will never end. For the Christian life is to live in intimate communion with God, now and forever.

Since the 1st century, Christians have prayed for the departed; they used to visit the tombs of the martyrs in the catacombs to pray for those who died without martyrdom. In the 4th century, we already find the Commemoration of the Dead in the celebration of the Mass. Since the 5th century, the Church has dedicated one day a year to pray for all the dead, for whom no one else prayed and whom no one remembered. Since the 11th century, Popes Sylvester II (1009), John XVIII (1009), and Leo IX (1015) obliged the community to dedicate one day a year to the dead. Since the 13th century, this annual day for all the dead has been commemorated on November 2nd, because November 1st is the feast of “All Saints’ Day.” All Saints’ Day celebrates all those who died in a state of grace but were not canonized. All Souls’ Day celebrates all those who have died and are not remembered in prayer.
