Read John 6:50-66 and get back to me on that “cult” nonsense.
1 Timothy 4:1-5 Now the Spirit expressly says that in later times some will depart from the faith by devoting themselves to deceitful spirits and teachings of demons, through the insincerity of liars whose consciences are seared, who forbid marriage and require abstinence from foods that God created to be received with thanksgiving by those who believe and know the truth. For everything created by God is good, and nothing is to be rejected if it is received with thanksgiving, for it is made holy by the word of God and prayer.
I looked up the scripture reference you provided.
There are none so blind as those who will not see.
