Q: Archbishop J, what are the sacred mysteries?
The Mass begins with the Sign of the Cross. Here, we are plunged into the mystery of the Trinity. God is one, yet God is three. The desire of this God—Father, Son and Holy Spirit—is that we may have life and participate in His divine life.
Immediately after we sign ourselves, the priest says: “Let us acknowledge our sins, and so prepare ourselves to celebrate the sacred mysteries.”
