This is the OLD testament. Even though it gives specific religious "rituals" it does not specifically adocate any specific religion. In the New testament, it tells you that in order to be "saved" all you have to do is believe that Jesus Christ was the son of God and died on the cross for your sins. It does not say that you must be Catholic, or Babtist, Methodist, etc....
Religion is man's creation...if God or Jesus specifically advocated a certain religion in the Bible, then all Christians would belong to the same church, because they would know which one is mentioned in the Bible.
