Why do Catholics kneel during Mass? We kneel because we are in the presence of God. Kneeling is a very meaningful and intimate gesture, and it expresses adoration and shows our reverence towards Him.
We live in a society today that in many ways has lost reverence for things which are holy and sacred. We approach God in a way that is casual, almost as if He is on the same level as us. This lack of reverence can reflect a lack of humility. When we kneel we remind ourselves that we are not God and we are not in charge; rather, we are only creatures before our Lord.
Kneeling in God’s presence during Mass emphasizes the Real Presence of Christ in the Eucharist, and how much we love and adore our King. St. Paul says, “that at the name of Jesus every knee should bow, in heaven and on earth and under the earth” (Philippians 2:10). Like St. Paul, we get down on our knees during Mass and humbly adore Him.
