All religions deviate from the Christianity that the Bible teaches, Jehovahs Witneses are the closest, though they the go too far by teaching doctrines of men. They will disfellowship you if you dont follow there doctrines, disfellowshipping is a spiritual version of being stoned to death, so, for instance, if they catch you smoking, they will in effect stone you to death for it.
Despite generally claiming to stick to what the Bible says, they do however, lead people away from perhaps the most important act for salvation, which is to partake of the Bread and the Wine that represents Jesus Flesh and his blood, at thier yearly Passover, or memorial, they pass it around and are told by thier leaders that they must refuse it, saying its just for the highest tier, the annointed.
Jesus however likened the bread to the Manna from Heaven which fed all the Hebrews and even the foriegners who accompanied them through the wilderness, he didnt liken it to the Holy bread tha was just for the priests, if you didnt eat the manna, you would have died, full stop, just like Jesus says about eating his flesh in John 6
53 Jesus said to them, “Very truly I tell you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. 54 Whoever eats my flesh and drinks my blood has eternal life, and I will raise them up at the last day. 55 For my flesh is real food and my blood is real drink. 56 Whoever eats my flesh and drinks my blood remains in me, and I in them. 57 Just as the living Father sent me and I live because of the Father, so the one who feeds on me will live because of me. 58 This is the bread that came down from heaven. Your ancestors ate manna and died, but whoever feeds on this bread will live forever.”
