Just checked out your link. It was the sight of seeing Muslims praying in public that brought Charles de Foucauld from a debauched life to the belief in God and to the practice of the one true holy Catholic Faith.
Like he did, the majority of Italians live as there were no God, or by paying lipservice and going through the trappings of the Catholic faith, by making a party of the practice of once only Sacraments, make a mockery of our faith.
Pray for the conversion of Italians to the true sincere practice of the Catholic faith.
So now what has this got to do with one deranged foreigner, whose religion we do not know, who ran amok in four churches. The man most likely needs an exorcism, whether he is muslim, Catholic, protest, spiritist or without any religion. That's my point, not to encourage more muslims into Europe.
