Paradox #1
The contradiction or conflict in Hebrews 9:20 could stem from the ritual use of blood in religious ceremonies. Some might see this as conflicting with modern views on the sanctity of life and non-violence. Using blood as a symbol or a means of purification might seem inconsistent with contemporary ethical beliefs that emphasize non-violence and the humane treatment of living beings.
