Why do you need to join anything when The Lord is right beside you?
Why don't you find him first and then go to these places, so you can be of some use?
Well that is what they want, put you to work, for coffee and donuts and a prayer of course
I assume by "god" you mean the christian "god". If so then yes. However those who are intelligent enough to use their brains know that you are free to pursue anything that allows you to grow spiritually in a healthy manner.
No, it's not. Depending on who you ask. It is a combination of Voodoo and Catholicism. Practitioners are annoyed that the Vatican won't recognize it as a Catholic religion.
Now, before you decide on it, have you thought it through? Santeria is not an easy path. Your godparents will have you doing very menial tasks. That year and seven days in white? Animal offerings to the Orishas? And your Orisha picks you, you do not get to choose.
Good luck if you can make it. I'd never last one summer in all those layers of white clothing. It isn't as simple as throwing on a white dress or a white tee shirt and shorts.
