two differences between santeria and voodoo?

what are two differences between Santeria and voodoo? and two proper ones not like oh one comes from here and one comes here. i mean like differences in beliefs. also what are two similarities in their beliefs?

Thanks!

Santaria was heavily influenced by Catholicism.

They are both idolatry and foolishness by ignorant superstitious people.

Santeria is based on Yoruba beliefs, whereas Vodou is based on Fon and Ewe beliefs. The Catholic influences are also from different areas: Santeria is mainly Spanish Catholic, while Vodou is mainly French Catholic.

Both religions believe in a single God who is served by spirits (called "Lao" or "Law" in Vodou and "Krisha's" in Santeria). They also believe in possession by the spirits through ritual song and dance. Each Lao or Irish has a particular rhythm and dance associated with him or her, which is played during celebrations. The devotees begin to dance, and as their dance becomes more frenzied they become one with the Laos or Krisha's. During the possession, the possessed person acts like the loa is supposed to act and dispenses advice and blessings to the Santeros or the Voduisants.

Both came to the western Hemisphere with slaves from West Africa - Nigerian of the Yoruba religion specifically.
I am from an island that practices aspects of both - we call it Shango (one of the gods).
Puerto Ricans call it Zhango and Brazilians Candomble, Haitians call it voodoo and American blacks roots. If you research the practice you will see it all came from the same source and in the same way.

It sounds like you are writing a paper for religious studies; if so, I encourage you to do some serious research and really come to appreciate these religions which suffer from all too many public misconceptions and misunderstandings. You say you don't want to hear "one comes from here and the other from here" but actually that's a good start to understanding their differences and similarities.

As for how they are the same: Both are African diaspora religions, rooted in African traditions with all of the animism, shamanism, honor of the ancestors, and ecstatic practices that this implies. Both are heavily influenced by Catholicism, because Catholicism offered a protective veneer to the African practices, and because Catholicism includes some of the same features of animism, shamanism, honor of the ancestors, and ecstatic practices (much of which was removed from Catholicism during the Protestant Reformation.) Thus, Catholics honor angels and saints; African Diasporas honor Laos and ancestors. Catholics employ their mystics and clergy; African Diasporas look to their local Hogan, mambo, gaga, etc, for help in contacting the spirit world. Catholics use relics, blessed items, medals, religious figurines, novenas, etc; African Diasporas rely heavily on their personal sacred items also. Until Vatican II Cathlolic worship services were quite stodgy; however, Catholicism has a strong tradition of mystics who levitate, live without food or water, heal with a touch, manifest Christ's wounds on their bodies, etc, and since Vatican II Catholic services have incorporated drums, dancing, and other ecstatic elements. African Diaspora practices can relate to all this.

As for how they are different -- to answer this you must again consider where they come from. Santeria developed in the Spanish speaking countries and was heavily influenced by the Spanish colonial culture, particularly that blend of Aztec and Spanish cultures which developed in Mexico. Voodoo (I'm guessing by your spelling that you mean voodoo as it's practiced here in the USA; Haitian VDUoir vodoun is spelled differently) developed here in the USA particularly in New Orleans and was influenced by French and American culture. It received a heavy infusion of Haitian culture when the middle class fled Haiti during the Haitian revolution and many settled in New Orleans, but it is much looser and more eclectic than Haitian vodou. Voodoo incorporates elements of US Catholicism, African-American rootwork as well as Neopagan practices such as Thelema, Wicca, and Khemet. So to say how they are different you must consider the different elements of these cultures.

It is also good to consider the meanings of the words in your question. Santeria means honor of the saints. In Santeria, the loas and ancestors are identified with Catholic saints; in addition, certain people who are called to a higher dedication go through a ceremony in which they become "asiento," saints. It is somewhat like an ordination to the clergy, very serious. Voodoo comes from an African word which means "spirit." Spirit is everywhere and in everything.

So you have a good question here and I hope you learn a lot about African diasporic traditions. A very good place to start in your understanding is to consider where they come from. Perhaps you are called to practice; more likely you are called to be an ally, someone who can help these traditions to survive and flourish, and defend them against persecution and misunderstanding.
