Couple of sermon notes:
A smattering of anti-sacrificial texts
1 Sam 15:22
Hos 6:6 (also referenced in Matt 9:13 and 12:7)
There are LOTS more, as this is a whole field of study in and of itself. If you ever want resources, I’ll point you in the direction of some great ones.
“charcoal fire” mentioned in John 18:18 (belongs to the scene involving Peters three-fold denial of Jesus) and again in John 21:9 (belongs to the scene of Jesus’ three-fold forgiveness of Peter and his commissioning).
Jesus does not demand Peter to splatter blood on an altar. He demands no sacrifice to God for forgiveness of sins. Instead, he sacrificed himself to human betrayal and brutality, and in doing so, exposed it for its futility. God never demanded that, but humans did and attributed it to God. What God desires is not sacrifice, but mercy. Here Jesus enacts that mercy for Peter. Peter’s “sacrifice” will be to feed Jesus’ sheep and to tend his flock — not to kill them and offer them to God.
