At the risk of rekindling the unpleasantness from last weekend, I wish to point out that this is the type of thing that has long been accepted in folk Catholicism without near the criticism from Catholic intellectuals that Biblical literalism receives.
Guess I just picked the wrong ancestors!
Give it a rest.
Actually, it was long criticized and suppressed, sometimes even very firmly (witness the Inquisition). However, after Vatican II, many leftists got into positions of power in the Church and started encouraging "native" practices. The left is the biggest reason that voodoo and various bizarre African-influenced cults have flourished in Latin America. I think our current pope is not going to be as tolerant as his predecessor.
