Blood has to be shed in order for the forgiveness of sins.
"Those who believe that one must have a blood sacrifice for the forgiveness of sins look to Leviticus 17:11, which reads:
For the life of a creature is in the blood, and I have given it to you to make atonement for yourselves on the altar; it is the blood that makes atonement for one's life." [Leviticus 17:11]
But if you read the whole context of this verse, you will find that it is in reference to abstaining from eating the blood of a sacrifice, and nothing more. God commanded the abstaining from eating or drinking blood because most other pagan religions ate the blood of their sacrifices as a way to incorporate their gods into their bodies and into their lives. (See The Golden Bough by Sir James Frazer, the chapter on "Eating The God." Perhaps this is the source of ritual communion?) But the Holiness of the People of Israel requires them to not practice the pagan ways and not to hold the same beliefs of their pagan neighbors.
The whole quotation from Leviticus 17 reads:
Any Israelite or any alien living among them who eats any blood-- I will set my face against that person who eats blood and will cut him off from his people. For the life of a creature is in the blood, and I have given it to you to make atonement for yourselves on the altar; it is the blood that makes atonement for one's life. Therefore I say to the Israelites, `None of you may eat blood, nor may an alien living among you eat blood. Any Israelite or any alien living among you who hunts any animal or bird that may be eaten must drain out the blood and cover it with earth, because the life of every creature is its blood.' That is why I have said to the Israelites, `You must not eat the blood of any creature, because the life of every creature is its blood; anyone who eats it must be cut off.'"
Many might still insist that blood is needed to atone for sins. But there are many examples in the TaNaCh where other things besides blood atone for sins. If you are poor and unable to afford a blood sacrifice, God allows you to use flour (which has no blood and is not an animal!). If the poor were not able to offer a sacrifice of flour, forgiveness would only be for the wealthy. God would never exclude humans from obtaining forgiveness on the basis of wealth.
If, however, he cannot afford two doves or two young pigeons, he is to bring as an offering for his sin a tenth of an ephah of fine flour for a sin offering. He must not put oil or incense on it, because it is a sin offering. He is to bring it to the priest, who shall take a handful of it as a memorial portion and burn it on the altar on top of the offerings made to the Eternal by fire. It is a sin offering. In this way the priest will make atonement for him for any of these sins he has committed, and he will be forgiven. The rest of the offering will belong to the priest, as in the case of the grain offering. [Leviticus 5:11-13]
So here, right in the midst of the commandments concerning the sacrifices for sin, the Bible tells us we do not need any blood sacrifice for the forgiveness of sin. This proves that the idea that one needs a blood sacrifice for the forgiveness of sin is an UnBiblical idea."

And don't Christians drink the blood of their sacrifice? Did God change his mind about that pagan practice?
