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.
The Spirit gives life. The flesh is no help at all>
Couldn't get much simpler.
You need to look at ALL of scripture, not just the verses that support your traditions.
According to you, you can just ignore this:
Jesus said to them, "I tell you the truth, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. John 6:53
unless you eat the flesh of the Son of Man and drink his blood, you have no life in you.
Throughout the Gospels Jesus refers to both "the flesh" and "my flesh". The two are not synonymous.
Peace be with you.
