Widely known as “All Saints Day”, the feast of All Saints is much more than just another Holy Day of Obligation. It is much more than just “the day after Halloween that you have to go to Church for”. It is the celebration of The Church Triumphant. It is a celebration of those who fought the good fight and are eternally resting in their Master’s House. It is a celebration of the Holy Souls who persevered to the end and enjoy the beatific vision, the neverending presence of Almighty God.
The Catechism of the Catholic Church paragraph 948 says:
The term “communion of saints” therefore has two closely linked meanings: communion in holy things (sancta)” and “among holy persons (sancti).”
Sancta sanctis! (“God’s holy gifts for God’s holy people”) is proclaimed by the celebrant in most Eastern liturgies during the elevation of the holy Gifts before the distribution of communion. The faithful (sancti) are fed by Christ’s holy body and blood (sancta) to grow in the communion of the Holy Spirit (koinonia) and to communicate it to the world.
My Catholic Faith lesson 93 puts it more simply:
2. We venerate the saints because they are the chosen friends of God, in Heaven.
If we are eager to show honor to earthly royalty, how much more should we honor the saints of God, princes of Heaven! If we ask for prayers of our fellowmen on earth, how much more eager should we be to ask the saints, our friends in Heaven!
Let us honor the friends of God, the Church Triumphant and pray for their intercession daily!
