The "partaking of the body of the Lord" is indeed life. And we "partake" of His sacrifice every day, not in the blasphemy of the mass which sacrifices him daily, but in our remembrance of His one-time sacrifice on the cross for all the sins of His elect by the grace that God has given us.
Christianity is not cannibalism. Grace is not found in the material, but in the spiritual. Rome continues to shove the material world in our faces when Christ tells us the truth is spiritually-discerned.
Continue to read Paul. He explained the teaching earlier in the chapter...
Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual. But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned. But he that is spiritual judgeth all things, yet he himself is judged of no man. For who hath known the mind of the Lord, that he may instruct him? But we have the mind of Christ." -- 1 Corinthians 2:12-16"Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God.
In one sentence fragment you both make Christ a liar and misrepresent Catholic belief.
Must be a day ending in 'y.'
You sure shot down that strawman with skill and daring.
Protestants secure their sanctification (the gradual transformation towards a glorified body and mind) primarily by their repentance and continual move towards increasingly ethical behavior. From what I am told by Catholics on FR, (and stop me if Im wrong) Catholics are sanctified primarily by the ingestion of the Eucharist. For Protestants, it is a question of ethics and behavior 24/7. For Catholics, it appears to be diet and confession, i.e. ingesting a unique and beneficial dietary supplement, akin to taking growth hormones, will itself cause a change in ones physical and moral makeup. Protestants = behavior. Catholics = participation in ceremony and diet.
