Is the Church
By "the Church", do you mean Christianity as its whole body of believers or do you mean the Roman Catholic denomination? If the latter, then yes, they are far more powerful in Poland than over there. Unfortunately for them, the 'JPII effect' is now finished and a trough always follows a peak.
They responded to that by intransigence, bloody-mindedness and lashing out which in turn has created animosity and (together with the COVID lockdowns when many people realised that they can not only manage nicely without going on Sunday but actually feel better for not going) added to the dramatic fall in mass attendance that Poland has seen in recent years. The RCC has found that hard to deal with and that, together with PiS' dog-whistling to its rural target voters by aligning with the RCC has intensified the problem.
