Except that voodoo doesn't "blend" anything. The names of Catholic saints have been substituted in the voodoo rituals for the original African names of spirits as part of the adoption of the French language and its cultural influences.
Besides, when did the UK Telegraph, which doesn't substantiate or attribute the "blended" claim, ever publish anything accurate or unbiased about Catholicism?
The question I would have is this:
When Voodoo worshipers who also claim Catholicism go to the church, do they take the Eucharist with the approval of the priests?
In the Philippines, one can walk from shop-to-shop, house-to-house, cafe-to-cafe, and see the god shelves on the walls, with red lights or candles, Buddhist figures (I’m taling about in areas where people from the Asian Mainland generations ago mingled with the native Filipinos) along with Catholic figures (figurines of Mary, Joseph and a “Santo Nino”). Somebody is blending something with something.
These go to the church and nobody questions anybody about their loyalty to Christ, or whether they have merely added a form of Christendom to their Buddhism. They still also abide my many of the Buddhist superstitions. You can purchase books on this very subject in the National Bookstore (chain).
They receive the “host” into their mouths without any scrutiny whatsoever. The church demands no allegience to Jesus Christ from these people, it would appear. It is impossible that the priests do not know this is happening-—this dual worship.
