From the only reliable source of Catholic news on the net, Eye of the Tiber:
At a press conference today in the nation’s capital, Cardinal Emeritus Roger Mahoney of Los Angeles announced that the USCCB is petitioning the Congregation for Divine Worship and the Sacraments to require that parishioners give a “good, humanity affirming squeeze” following the doxology which concludes the Lord’s Prayer during Mass.
“God’s people have been spontaneously doing this for years anyway,” Mahoney told EOTT, “We just want to bring uniformity by removing the awkward part. The people will now proudly raise their hands, which are held together as they have been doing, but when they finish praying ‘for thine is the Kingdom, the power and the glory, forever and ever, amen,’ they will give that last squeeze, which is meant to communicate, ‘Don’t worry friend…I’m here for you until the very end of Mass.’”
When told about this Pope Francis responded, “They aren’t going to sing Kumbaya then are they? No? Good! Nothing sillier than a bunch of gringos and gringas holding hands and trying to sing!”
