Interesting OP. I went to a catholic school and Easter played a big part in the religious calendar, as it did for me at home because my parents were very catholic. On the run up to Easter we seemed to be permanently in church Maundy Thursday mass, Stations of the Cross on Good Friday, maybe there was something on Saturday and then of course Easter Sunday Mass. The Stations of the Cross deals stage by stage the agony Christ suffered before he was actually crucified which we knew to be a long an agonising death. In retrospect I do think young children should be spared such frightening details. At my school it wasn't only the crucifixion we were also subjected to gruesome deaths suffered by martyrs, one I particularly remember was a woman who was pressed to death by heavy stones in York, Tudor times, these were often related to us by nuns who seemed to relish imparting how agonising their suffering was, they left a feeling of anxiety, being of a young age and where it was almost suggested that this is what you must do "die for your faith" if necessary, my inner thoughts were "just convert to whatever" So yes I would have been more than happy to have an adult step up with a "thank you that's enough"
I think I went through a stage of deliberating whether to send my own children to a catholic school or not but I think my husband persuaded me that young children don't need to have the life frightened out of them, so we opted for a CofE school. I thought they got the balance right in the way they taught religion insomuch as not dwelling on the frightening and gruesome. Although my children did go to a holiday club attached to a church, can't remember which denomination, although they really loved it, kept them very well occupied with both sporty and arty activities, perfect for mine one liked sports and the other was very into art. I do remember one of my boys, aged about 5, unbeknown to me until he came home had been learning about the crucifixion, it was the Easter holidays, when he told me "Jesus had a crown of thorns put on his head, he found it quite unpleasant " an understatement if ever there was one.
