A campaign promoting atheism on London buses this year ultimately “served God’s cause” by reminding people of the importance of faith, especially to those who suffer, a papal preacher said Friday. The campaign involved paying to have the slogan “There’s probably no God. Now enjoy your life!” placed on buses. “We should almost thank the people who promoted that advertising campaign. It has served God’s cause more than so many of our apologetic arguments,” said the Rev. Raniero Cantalamessa, whose title is preacher of the papal household. He added: “It has demonstrated the poverty of their reasons and has helped stir so many sleeping consciences.” He was preaching in St. Peter’s Basilica in the presence of Pope Benedict XVI on Good Friday.
