Has Jesus gone on record as correcting anyone's theology?
He sure complained about their PRACTICES!
Your comment: “Has Jesus gone on record as correcting anyone’s theology?”
Yes. The Jews quarreled among themselves, saying, “How can this man give us [his] flesh to eat?” 53Jesus said to them, “Amen, amen, I say to you, unless you eat the flesh of the Son of Man and drink his blood, you do not have life within you. 54Whoever eats* my flesh and drinks my blood has eternal life, and I will raise him on the last day. 55For my flesh is true food, and my blood is true drink. 56 John 6
