Despite what He Himself said. A shame there weren't some 21st century protestants there to correct Him.
No need to correct anything I agree with all Jesus words.
Jesus said
“ John 15 - 4. Abide in me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in me. 5. I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing. 6. If a man abide not in me, he is cast forth as a branch, and is withered; and men gather them, and cast them into the fire, and they are burned. 7. If ye abide in me, and my words abide in you, ye shall ask what ye will, and it shall be done unto you.”
Nothing said here about eating physical bread to have him abide in them. Christ dwells in our hearts by faith.
As believers abide in him through faith he abides in them.
Paul preached the gospel of salvation and he didn’t add water baptism, the Lords supper, circumcision, the Mosaic law, etc. If any add to this gospel they are making another gospel.
He also said they are saved IF they KEEP in memory the gospel . The supper helps to remember Christ work as a remembrance of him. This is how we are in Christ thrpugh faith not by literally eating bread. Christ dwells in the hearts of all believers and this common union we have is through his death and shed blood and his resurrection. All believers are parts of the body of Christ (1 Cor 12,Ephesians 1, etc etc) and we being many are one body and one bread and we are all parakeets of that one bread. As the body of Christ all believers have Christ working in them and they are then able to feed one another and edify one another and partake of the body ministry in Christ being one body and one bread.
But as for the saving gospel consider this below and notice no mention of eating bread and drinking the cup literally for salvation. Those things help us to keep in memory the wrk of Christ, but the reality is inward .Jesus said he would come into men and sup with them.
1 Corinthians 15 - 1. Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand; 2. By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain. 3. For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; 4. And that he was buried, and that he rose again the third day according to the scriptures:”
