This Holy Day honors all the saints of the Church, known and unknown, whose virtues and efforts in this life are considered to have earned them an eternal reward with God. On this day, Catholics are asked to reflect on holiness and sainthood and to celebrate the holiness of men and women who gave their lives in faithfulness and service to God, and whose witness continues to inspire us today.
Mass for All Saints’ Day will be November 1 at 7:00 p.m.

On All Souls' Day, Catholics commemorate and pray for the holy souls in Purgatory, undergoing purification of their sins before entering heaven. The theological basis for this feast is the doctrine that the souls which, on departing from the body, are not perfectly cleansed from venial sins, or have not fully atoned for past transgressions, cannot not yet attain the Beatific Vision, and that the faithful on earth can help them by prayers, alms, deeds and especially by the sacrifice of the Mass.

All Souls Reprint: On the Use of Black Vestments for Masses for the Dead
But why do so? At times in the past few decades, some individuals have attempted to make the argument that the use of black is contrary to Christian hope in the resurrection of the dead. Accordingly, some of these same individuals have agitated against the use of black -- even violet -- for these occasions, despite the Church's continued use of that liturgical colour. In response, I would point out that this is not a case of either-or, but rather one of both-and. While Christians are indeed a people of hope rooted in the resurrection, this does not invalidate the natural emotional response of sorrow or mourning, nor that fact that we are likewise to be aware of the reality of sin, death and judgement. Such awareness and reserve is simply that, an awareness and reserve which springs from a recognition of a genuine spiritual reality, and the mere fact of this cannot be equated with hopelessness or an insufficient hope in the resurrection of the dead. In point of fact, not giving adequate recognition to these realities is itself a problem.
