IF you ever study the why for the pouring out of the blood rather than ingesting it, you will be gob smacked at the arrogance of assuming a catholic priest can offer you the blood to drink or in a wafer. You can refuse to awaken to Truth, but it is not wise.
Jesus would not violate IN ANY WAY the laws He came to fulfill, one of which is found in Leviticus 3:17. His Flesh He offered up upon the cross for you and for me. His blood was poured out upon the ground at the foot of the cross fulfilling something begun in the time of Abel, son of Adam. His blood was also sprinkled on the Mercy above the laws of sin and death.
The Mercy Seat was right over the books of the laws in the ark below the Mercy Seat. When God looks (we are being figurative) down at the laws to weigh you against His righteousness, He sees the perfect righteous blood of Jesus and not past that perfection. He does not see the laws of sin and death because The Blood of Jesus Christ covers those laws for you.
I’m asking you for a purely literary answer.
