After this I had a vision of a great multitude, which no one could count,
from every nation, race, people, and tongue.
They stood before the throne and before the Lamb,
wearing white robes and holding palm branches in their hands.
They cried out in a loud voice: "Salvation comes from our God, who is seated on the throne, and from the Lamb"
Forget "trick or treat"!
This the real meaning of All Hallow's Eve or Hallowe'en. Hallows is an old English word meaning "saints". Hence we speak of something being "hallowed" i.e. made holy.
This tableau is a powerful representation of the Church militant, here on earth, and the Church triumphant, in heaven.
On earth we see the Pope, clergy and religious on the left and the Emperor, nobility and people on the right.
Above them we see the Holy Trinity, with our Lady and the martyrs on the left and St Joseph and the other saints on the right, above them both are the holy angels, all adoring the Trinity.
It demonstrates, too, the essentially familiar and Trinitarian heart of the Church: the Holy Family is a reflection of the Holy Trinity and the charity that must obtain within a family is a reflection of the charity that obtains within the Holy Family and the Holy Trinity and is the foundation of heaven.
The Church, then, is a society founded upon the family and upon familiar principles which, in turn, are Trinitarian and incarnational principles, incarnating the love of God for men and the filial duty of men, in turn, to love and adore God the Father of all.
This the saints have done and do now to perfection, setting an example for us all to imitate.
