I. Who Celebrates?

From The Catechism of the Catholic Church

1137
The book of Revelation of St. John, read in the Church’s liturgy, first reveals
to us, “A throne stood in heaven, with one seated on the throne”:
“the Lord God.”¹ It then shows the Lamb, “standing, as
though it had been slain”: Christ crucified and risen, the one high priest
of the true sanctuary, the same one “who offers and is offered, who gives
and is given.”² Finally it presents “the river of the water
of life . . . flowing from the throne of God and of the Lamb,” one of most
beautiful symbols of the Holy Spirit.³
