The Christian faith of the developing world is more traditional, more conservative than the Christian faith of the west. This is true of Protestants and Catholics alike.Yes and no. Cardinal Arinze may be a conservative, but other African Bishops of the RC and Anglican persuasions are way out there in animist, polygamous, socialist radical land. Also, Third World Christianity often tends to blend Christian tenets with native religions.
Your left-wingers love this. So colorful! And it proves for them that all religions are the same and equal.
Such is the nature and history of the Christian faith. Always side stepping this way and that but with the core always enduring. Did you catch Philip Jenkins Atlantic Monthly article last October entitled
The Next Christianity ? Huge demographic changes afoot. Africa is nearly 50% Christian, up from 10% a century ago--the community of Christian faith, as it did in medieval times, supercedes the nation states of the continent (which are failing as we know). There are more Catholic baptisms in the Philippines than in Italy, France, Spain and Poland combined. Pentecostals, nearly 400 million strong, may reach 1 billion in the next 35 years. They too, are heavily represented in the developing world.
Jenkins also goes into details about the perversions of faith you mention. Some weird "Christian" religions popping up in Africa and South America.
