Every Christian has been chosen by God to commune with Him. Because of the Third Person of the Trinity, no third person among men can get in the way of that. A minister can attempt to position himself in between, and a minister can muddle up his representative service, but a minister can’t stop the Father from feeding His elect.
Jesus taught about His flesh as bread and His blood as wine in John 6. Though Jesus wasn’t teaching about or instituting the Lord’s Supper at that point in His ministry, certainly the Holy Spirit connected the realities of feeding on Him with communion to the disciples later.
The people were hungry in John 6, and followed Jesus around the sea for more loaves. He identified Himself as “the bread of life,” and promised that “whoever comes to me shall not hunger, and whoever believes in me shall never thirst” (verse 36). But it wasn’t for everyone.
All that the Father gives to me will come to me, and whoever comes I will never cast out. (verse 37)
No one can come to me unless the Father who sent me draws him. (verse 44)
No one can come to me unless it is granted him by my Father. (verse 64)
Some said that His teaching was hard (verse 60). Some who had been following him turned back and no longer walked with Him (verse 66).
But the reality is,
Whoever feeds on my flesh and drinks my blood abides in me, and I in him. (verse 56)
If you’ve been given by the Father to the Son, no man can stop you from feeding on Jesus. If the Father has drawn you, no man can interrupt Jesus abiding in you. Our liturgy celebrates that fact of our communion with God through Jesus, but our liturgy does not create it. He is yours, you are His. He gives you eternal life, and no one can snatch you out of His hand (John 10:28).
