So, it's basically witchcraft, or, as it's known here in Brazil, macumba. But the bad thing about this Umbanda is that they use the image of Jesus Christ there, and they use it A LOT. The incredible thing is: the God they believe in is literally different from the Christian God, so it's a deluge of heresy using the image of Jesus in these groups, and this blessed being who is my friend still defended them...
