The difference is. Did Jesus break the law and cause others to break the law?
Leviticus 17:14 You shall not eat the blood of any creature, for the life of every creature is its blood. Whoever eats it shall be cut off.
You can be flip all you want. But if Jesus broke the law by investing blood He broke the law and cannot be the perfect lamb.
Now, do you believe Jesus ate His own flesh and drank His own blood or not?
investing = ingesting
Where do you invest blood, at a blood bank?
Define ‘flesh and blood’ as there used — or as intended in that context in which it arose.
