Your comment:”what the catholic church teaches about the literal blood and flesh of Jesus must be in error”
No what you are saying is false.
The Catholic Church teaches what Jesus told us and was stated very explicitly in several places in the Bible and that he meant the exact words of “His Body and Blood” that were necessary for eternal life.
You can ignore the words of Jesus, but you are a false teacher if you state that Jesus and the Catholic Church are in error.
May God help you understand.
There is no way to be justified before God by any gastronomic process. It IS the Body sacrificed upon the Cross that is for your salvation, not the unleavened bread of the Eucharist which is for the remembrance of the sacrifice. It is by FAITH that you have His sacrifice when you take the unleavened bread, not by ingesting unleavened bread as the literal body of Christ. It is BY FAITH that His blood is shed for you and spread upon the Mercy Seat top cover the law of sin and death for you. It is not by swallowing the literal blood of Christ to be eventually expelled through the drought. Jesus said it is the words that he speaks:
John 6:63 It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life.
John 14:10 Believest thou not that I am in the Father, and the Father in me? the words that I speak unto you I speak not of myself: but the Father that dwelleth in me, he doeth the works.
Romans 1:17 For therein is the righteousness of God revealed from faith to faith: as it is written, The just shall live by faith.
Romans 3:22 Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference:
Romans 3:28 Therefore we conclude that a man is justified by faith without the deeds of the law.
Romans 9:32 Wherefore? Because they sought it not by faith, but as it were by the works of the law. For they stumbled at that stumblingstone;
Seeking absolution of sin by deeds of the flesh (eating His body, literally, drinking His blood, literally, constantly going to an institutional priest to confess and get forgiveness of sin, doing alms, doing good deeds) which generate pride in self does not obtain Justification. Of such trusting in works will Jesus declare, 'Depart from me, I never knew you.'
Since when has Jesus EVER been recorded as being in TWO places at once?
