Christianity has about two billion adherents world-wide. At the same time, there is no other religion with so many internal divisions. The number of movements and interpretations is enormous, not in the least as a result of Western colonialism. That brought Christianity to unexpected places, where, mixed with local traditions, it evolved into new variants. The integration of pagan rituals was often encouraged by missionaries, so that the Christian faith they taught would fall on more fertile ground. Jan Locus has photographed Christianity all over the world.

Freelance photographer Jan Locus (b. 1968, Belgium) sometimes works for years on reportages. In 2004 his book Mongolia received the Plantin-Moretus Prize. Ex-Voto is a work in progress.
