Even if I accept your premise that blood sacrifices are of great importance in the Torah, the fact is that our Hebrew Bible -- including the Torah itself -- offers other means of atonement, not just the shedding of blood."
Brown says:
"There can be no question that blood atonement is the central and most important form of atonement in the Bible."
There may be no question to Brown -- but Torah sure disagrees with him!
Qorbans (sacrifices -- not even just blood sacrifices) are ONE way to atone for very specific sins -- they were never the only way to atone. And as we've discussed before there are many things that are used for qorban (translated as sacrifice) and these can include money, jewelry, flour, etc.
If you start with Leviticus 4 and read on you’ll find the following:
Sin Offerings for the High Priest
Sin Offerings for the Community
Sin Offerings for the King
Sin Offerings for Commoners
The Adjustable Guilt Offering
The Meal Offering for Guilt
The Misappropriation Sacrifice
The Offering for Questionable Guilt
Offerings for Dishonesty
The High Priest's Offering
Purification of a Leper
The Poor Leper's Offering
Priestly Yom Kippur Offering
Communal Yom Kippur Offering
Fast on Yom Kippur
I stopped at Leviticus 16, because these should make it clear enough that there are many, many different types of offerings and they are not all inclusive. Some are for priests, some for kings, some for commoners, some for the entire community and some for individuals. Just start at Leviticus chapter 4 and read forward.
And just as there are many of different reasons for sacrifices, so too are there many different rules. So to synopsize:
1. there are different qorbans (sacrifices) for different people
2. there are different qorbans (sacrifices) for different purposes – some for peace, some for sin, some for guilt, some to give thanks, etc.
3. There are distinct qorbans (sacrifices) for individuals, the community, kings, and priests. Each has its own purpose.
4. The goat sent off into the wilderness is not halachally sentenced to death. Torah decrees that it be sent far away. It is a gezeirah (rabbinical fence) that decreed it be sent over a cliff. http://dafyomi.shemayisrael.co.il/yoma/ ... -ps-67.htm
Keep in mind that after the Exodus and prior to Sinai there were NO sacrifices yet G-d forgave the sins of the Israelites many, many times during that period.
Likewise there were no sacrifices in Egypt prior to the paschal lamb (although Moses asks to bring them).
So it helps to keep in mind that qoran (sacrifice) many of which don't involve blood at all is merely ONE way to atone and repent, not the only way. Prayer wasn't a "substitution" as many suggest -- it was always there.
Now when there is a Temple and we are allowed to bring sacrifices (and as you point out we live where we can bring them) we are REQUIRED to do so. If we live far away but can arrange to pay for a sacrifice we do that -- although it is not as much of a mitzvot as actually going there and bringing it yourself (part of the act of bringing qorban is to lay your hand on the item being given).
We are obligated by our covenant with G-d to follow His mitzvot.
Without a Temple we are forbidden from bringing sacrifices.
