On the Solemnity of All Saints, the Church celebrates all who have been canonized or beatified, and the multitude of those who are in heaven enjoying the beatific vision that are only known to God.
I, [John], 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." -Revelation 7:9-10
