Vatican City, August 2 - An annual message sent from the Holy See to Muslims around the world as they celebrate Id al-Fitr, the breaking of the Ramadan fast, was personally written by Pope Francis, on Friday. The last time a pontiff wrote the message himself, which has been sent by the Pontifical Council for Interreligious Dialogue since 1967, was when Pope John Paul did so in 1991. "We are called to respect the religion of the other, its teachings, its symbols, its values. Particular respect is due to religious leaders and to places of worship. How painful are attacks on one or other of these!," Pope Francis wrote. The pope underlined the importance of educating Muslim and Christian youth, saying that "we have to bring up our young people to think and speak respectfully of other religions and their followers, and to avoid ridiculing or denigrating their convictions and practices. "We all know that mutual respect is fundamental in any human relationship, especially among people who profess religious belief. In this way, sincere and lasting friendship can grow," the pope said.
