[Steelfish]

“believes in Him”

Precisely:

“He that eateth my flesh, and drinketh my blood, hath everlasting life: and I will raise him up in the last day.”

John 6:63 It is the Spirit who gives life; the flesh is no help at all. The words that I have spoken to you are spirit and life.

Eating Jesus, breaking the commands of God in consuming blood, does not save anyone.

Again, an example of Catholic teaching that it's works, what you do, that save you, and not faith, as Scripture teaches.
