The lack of understanding could be on the other side. In no place do I see Jesus rebuke anybody for not repeating "magic words". Jesus looked upon the heart. Jesus knew what was inside of them. The Catholic Church does not know where the True Church is or Who the Head of it is. (Hint: It ain't in Rome and it ain't the Pope). Jesus fought against religious authorities who ritualized and commercialized the worship of God. They were the ones who incited the people against Him.
Peace be unto you.
2 Thessalonians 2:15
“So then, brothers, stand firm and hold to the teachings we passed on to you, whether by word of mouth or by letter.”
Jesus rebuked Jews, not Christians for standing firm in their traditions. Paul’s quote above shows that Christian traditions should be held.
