Pope Francis suggested Thursday there are limits on freedom of expression, especially when it comes to ridiculing religion, NBC News reported. The pontiff spoke about the the massacre at Paris satirical magazine Charlie Hebdo Thursday while on his way to the Philippines on a tour of Asia. The pontiff said that both freedom of faith and freedom of speech were fundamental human rights and that "every religion has its dignity." "One cannot provoke, one cannot insult other people's faith, one cannot make fun of faith," he said. The Pope also promised to canonize Junipero Serra, a missionary who brought Christianity to the western United States in the 1700s, during his visit to America in September.
