Pope Francis, the current Pope of the Catholic Church, is perhaps one of the most liberal members the Vatican has ever seen.
He's not afraid to state his opinions about his religion and suggest changes if necessary.
From the moment he stepped onto the balcony at St. Peter's in Rome as Pope, he put a new emphasis on poverty and simplicity. He has embraced a man with severe facial disfigurement and washed the feet of a group of young offenders, things that have never been done by previous popes.
He preaches mercy, and hopes that religion will be a way to unite and better people.
Last year, the Pope issued a worldwide survey of Catholics asking for their views on single parent families, contraception, and gay marriage.
Now he has a new task to enrich the lives of his religious followers.
Pope Francis wants to change a line in Christianity's best-known prayer.
