If the Holy Spirit tells us that we have the same grace, I’m not going to argue.
He wrote 1 Corinthians under the inspiration from the Holy Spirit.
If the Holy Spirit tells us that the Bread and wine become the Body and Blood of Jesus who am I to argue.
1 Corinthians 11:26-29: For as often as you eat this bread and drink the cup, you proclaim the Lord's death until He comes.Therefore whoever eats the bread or drinks the cup of the Lord in an unworthy manner, shall be guilty of the body and the blood of the Lord.But a man must examine himself, and in so doing he is to eat of the bread and drink of the cup.For those who eat and drink without discerning the body of Christ eat and drink judgment on themselves.
I received from the Lord that which I also delivered to you, that the Lord Jesus in the night in which He was betrayed took bread; 24and when He had given thanks, He broke it and said, “This is My body, which is for you; do this in remembrance of Me.” 25In the same way He took the cup also after supper, saying, “This cup is the new covenant in My blood; do this, as often as you drink it, in remembrance of Me.” 26For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until He comes. 27Therefore whoever eats the bread or drinks the cup of the Lord in an unworthy manner, shall be guilty of the body and the blood of the Lord. 28But a man must examine himself, and in so doing he is to eat of the bread and drink of the cup. 29For he who eats and drinks, eats and drinks judgment to himself if he does not judge the body rightly. 30For this reason many among you are weak and sick, and a number sleep. 31But if we judged ourselves rightly, we would not be judged. 32But when we are judged, we are disciplined by the Lord so that we will not be condemned along with the world.
If Peter is used as the voice of SATAN; who am I to complain?
