One of the precepts of the Catholic Church: To contribute to the support of the Church.
Perhaps, one of the best ways -- especially in trad chapels/churches -- would be to earmark contributions for relatively low cost anti-bugging equipment for our confessionals. I wonder how the reactions of the priests would vary. For doubting Thomases or rather doubting priests one might want to place a small hidden device into the confessional and then go through a test run to see how easily the recording was detected. Discretion advised! You don't want to be branded as the chapel loon (unless you already are) by the priest and end up accomplishing nothing.
