Importantly, communist nations with Catholics and other Orthodox established a priority early on that all confessionals must be electronically bugged, because what was said within was of intense interest to the secret police.
Since doctor-patient confidentiality has been effectively destroyed by HIPAA, the confessional has become the most important target of the authoritarian in the US.
(I might add that government wants total control over all religious sacraments, marriage being just the most recent to be absorbed. Eventually government wants recognition as “god”, taking over the role from God.)
Very good comment.
