A popular religion founded by a pacifist proto-socialist who promoted social justice, tolerance, and peace. Jesus Christ was a remarkably liberal man for his time, accepting prostitutes and murderers, among others, into his group. Unfortunately corrupted over the years, some branches of Christianity now seem to promote the opposite of the religion's founding aims, drawing on the works of St Paul, an evangelist who lived 50 years after the death of Jesus Christ. These sects of Christianity reverently follow Paul's interpretation, but refuse to accept any more modern interpretations of Christ's life.
Nevertheless, most mainstream Christians, (that is mainstream in the European sense, not the American sense) continue to try to fulfill the original aims of the religion. Please don't judge Christianity on a few mad sects in America and a old-fashioned German pope. Despite getting the most media coverage, they do not accurately represent Christianity and most Christians.
Archbishop Rowan Williams, Cardinal Hume and Mother Teresa are all people who try/tried to follow true Christianity.
