All Souls Day, or The Commemoration of All the Faithful Departed, is a day to remember and pray for the Holy Souls in Purgatory.​​

Catholics believe that a soul must not bear the stain of sin if it is to enter Heaven. If one dies with a venial sin on one's soul, he/she must first go to Purgatory to be cleansed of sin.​​

The faithful are strongly encouraged to attend Mass. The Holy Sacrifice of the Mass and our prayers are essential in helping the poor souls in Purgatory enter Heaven.
