Man has always beleived he has understood the teachings of spirituality, from before Jesus.... and what has changed? Nothing under the sun has changed. Judge not and be not judged it is said.
The vicar is giving his opinion and that is all it is. Until he can walk on water, he should still be learning, not law giving.
Jesus himself, was judged wrong by the establishment of his day. If you must judge, do so after prayer and meditation.
