That’s nonsense. You are lost when you don’t accept Him into your life and walk with Him. Eating a wafer won’t do it. The wafer has no magical significance in salvation. Your CHOICE to receive Christ as Saviour does.
"I am the living bread which came down from heaven. If any man eat of this bread, he shall live forever: and the bread that I will give is my flesh, which I will give for the life of the world."
The Jews therefore strove among themselves, saying, "How can this man give us his flesh to eat?"
Then Jesus said unto them, "Verily, verily, I say unto you, Except ye eat the flesh of the Son of man, and drink his blood, ye have no life in you. Whoso eateth my flesh, and drinketh my blood, hath eternal life; and I will raise him up at the last day. For my flesh is meat indeed [real meat], and my blood is drink indeed [real blood]. He that eateth my flesh, and drinketh my blood, dwelleth in me, and I in him.. As the living Father hath sent me, and I live by the Father: so he that eateth me, even he shall live by me.
"This [Himself] is that bread which came down from heaven: not as your fathers did eat manna, and are dead: he that eateth of this bread shall live for ever."
These things said he in the synagogue, as he taught in Capernaum.
Many therefore of his disciples, when they had heard this, said, "This is an hard saying; who can hear it?"
When Jesus knew in himself that his disciples murmured at it, he said unto them, "Doth this offend you? What and if ye shall see the Son of man ascend up where he was before? It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life. But there are some of you that believe not." For Jesus knew from the beginning who they were that believed not, and who should betray him.
And he said, "Therefore said I unto you, that no man can come unto me, except it were given unto him of my Father." From that time many of his disciples went back, and walked no more with him.
Then said Jesus unto the twelve, "Will ye also go away?"
Then Simon Peter answered him, "Lord, to whom shall we go? thou hast the words of eternal life. And we believe and are sure that thou art that Christ, the Son of the living God."
John 6
28. Then they asked him, "What must we do to do the works God requires?"
29. Jesus answered, "The work of God is this: to believe in the one he has sent."
