Being a nominal Catholic in one of the world's poorest countries doesn't make you immune from the attraction of the ancient religion of your ancestors.
Voodoo is supposedly based, roughly, on Vodun worship in West Africa. It's akin to Santeria except that it has no apparent Hindu elements.
It's kind of like being a Catholic in the United States while practicing Democrat party strategies which include killing babies, only better since killing babies isn't part of the deal.
And wouldn’t you think that there are other parts of the world that would be more deserving of God’s wrath, like, say the Muslim countries? I mean if you are a true-believing Christian, isn’t Islam the complete antithesis?
Nor does being a nominal Christian in one of the world's richest countries.
