When Abraham was asked to sacrifice Isaac and then was stopped, it was analogy for the fact that it was the common practice. It did not stop, it only went 'underground' and that power hungry faction would always rise to the top, be discovered, and subsequent destruction caused a new era and another book of the bible written to document the cycle. 'And the church shall become the whore'.

Jesus overthrowing the money-changers on the steps, was due to the charging of money to buy doves to sacrifice in place of your firstborn or later your best fatted calf or lamb. This in fact, later became Income Tax.........your sacrifice to the altar of government religion.

The eucharist is residue from the ritual. The literal sacrifice of his own literal son by the literal god of literal christianity.

This word sacrifice. Once the spiritual understanding is gained, the sacrifice of 'self' is a thing to rejoice in, and the literal death ritual can be deposed. This was and still is....the Good News. (gospel) imitated.
