From the only reliable source of Catholic news on the net, Eye of the Tiber:
VATICAN––Shortly after it was revealed that his predecessor, Pope Emeritus Benedict XVI, defrocked 400 priests for sexual abuse of minors, Pope Francis decreed the immediate removal of priestly faculties for 300 priests from Europe and the Americas who were found in defiance of liturgical norms and persistently refused to greet parishioners with the traditional “Good Morning” liturgical salutation. “The rubrics are clear in this regard; the celebrant is to smile, holds his hands out widely and welcomingly, and say ‘Good Morning,’ in a jubilant voice, before continuing with the Penitential Rites,” said a spokesman for the Holy See, defending the Holy Father’s decision. He continued, “a committee has been established also to ensure that liturgical norms for homilies are followed strictly by all who preach at Mass.” These norms, he explained, are somewhat more flexible: “the priest or deacon or layperson with a degree in theology or pastoral ministry has the option, in this case, of beginning with either a story or a joke. But beyond this, there is little wiggle room. Defying this would be the liturgical equivalent of deliberately changing a note in Marty Haugen’s ‘Mass of Creation’ setting for the Eucharistic Prayer, the Canonical penalty for which is an automatic excommunication.” The spokesman concluded firmly: “We are not at liberty to tamper with the Holy Liturgy of the Church, adding and subtracting as we see fit. That would make it more about us than about God.”
Well, OK, although PopeWatch would prefer the defrocking of priests who sing off-key loudly.
