unless you eat the flesh of the Son of Man and drink his blood,you do not have life within you.

So, you believe taking the Eucharist is necessary for salvation?

whoever eats this bread will live forever

Whoever eats my flesh and drinks my blood has eternal life, and I will raise him on the last day.

So, you believe taking the Eucharist is sufficient for salvation?

[Salvation]

In worthiness, yes, which means the use of the Sacrament of Penance/Reconciliation too.

Initially a baby or an adult baptized has all their sins washes away, so that they may then receive the Sacrament of the Eucharist if they do not sin.
