This from one of the sites that came up when I googled the subject:
It is part of the rich tradition of our Catholic faith to petition the popes regarding the proclamation of Marian dogmas. For example, millions of petitions by the Christian faithful led to the dogmas of the Immaculate Conception (1854) and the Assumption (1950). With every Marian dogma, extraordinary graces are poured upon the world through Our Lady’s most powerful intercession.
Petitioning for dogmas? Must be a new kind of bingo night.
Kinda takes away the argument of Peter and the successive popes having been appointed as "head" of the church.
If the pope is the head of the church, why does he need an opinion poll, or a groundswell of opinion, to declare a dogma.
If this is "true" then the pope should just declare it. That he doesn't tells me it isn't.
