From CNA--Cardinal Canizares speaks. And here's commentary from Father Z's blog:
"No renewal of the Church can take place without a revitalization of our Catholic identity. No revitalization of our Catholic identity can take place without a renewal of our liturgical worship.
Without a renewal of our Church, our identity, our worship, we as Catholics cannot have an effective impact on the world around us. We cannot fulfill Christ’s great command before His Ascension.
In the presence of God we must adopt the posture of creatures, and for just a few seconds… just a few seconds of our oh so busy lives… make ourselves lowly.
Aside from those because of physical reasons cannot kneel, for those of you think think you have to stand when receiving Communion, I invite you to rethink your “position”.
Do not be afraid to bend yourself and lower yourself before the coming of the Most High God, in the mystery which envelops you during Holy Mass.
Don’t think you mustn’t and can’t kneel to GOD."
Here's more on kneeling from Fr. Z.
