"The Mystery of Faith," which the priest proclaims after the Consecration, is the wonderful, unimaginable, yet so very true fact: that what was once only bread and wine is now the Body, Blood, Soul, and Divinity of Jesus Christ Himself. Right here with us! That's the Mystery of Faith!
What the lay people do is joyously respond to this statement of glorious. And it's a privilege to do so!
Let's learn how to do this properly. The best way, of course, is through chant. Learn this and enhance your elation at proclaiming our awe and wonder and gratitude to Jesus, for what He did for us.
