I've benefited greatly from reading Michael Morales, Who May Ascend the Mountain of the Lord. (My morning study is, by necessity, very short so I will be in this book a long time.) I'm wondering about the significance of the ceremonial slaughter of the sacrificial animals. He argues the participant is acknowledging the right judgment of God and willingness to die to self. These might be important aspects, but it seems that reference to the covenant is absolutely essential. I.e., under Abraham, when the animals were divided, the parties of the covenant took to themselves the oath they would be torn asunder if they did not keep the provisions of the covenant. The animals in the sacrifices take the result of the fall (death) and the legal requirement of the covenant. Ultimately this transference is taken onto the perfect Lamb himself. The author goes on to acknowledge there is no remission of sin apart from the blood, but it seemed he might be missing the particular significance of the ceremonial slaughter?
