TK421, to whom you replied, didn’t mention a priest in his answer.
Are you instead referring to Greenfields suggesting that the person ask their priest?
What is wrong with a suggestion to consult a priest? Priests are generally supposed to be the local experts on Catholic teachings, and many of them do an okay job at that (some are better than others), but in any event there’s no reason for you to object vehemently to the suggestion that people should ask their priest.
We also tend to tell people to talk to their priests when they have some kind of a personal problem that is not well suited to discussion on an Internet forum, or when they are insisting on some weird interpretation of Catholic teaching over and over and won’t listen to other people’s reasonable explanations pointing out their error.
I’m also not sure what you mean by priest has “so much power”. If you had a legal question, you’d ask a lawyer. If you had a medical question, you’d ask a doctor. If you had a theological question, you’d ask your priest. Simple as that.
