In the first part of the Roman Catholic Mass there is a prayer called the Confiteor in which the congregants say a prayer begging forgiveness for their sins and are supposed to beat their chest with a closed fist.
Before 1970, this was done 3 times during the prayer. After 1970, only once was required - but in general practice in the USA almost no one does it anymore.
As far as I am concerned, its slough into abeyance is a scandal.
I think that is one thing our two religions have done right - focused on we mortals and our senses and bodies with rituals that repeat and become more and more meaningful and help us reach our souls through our mortal senses. I like that about the Catholic church. Me as a Jewish woman lighting the candles... maybe at first it was just a simple act, but over the years, that special time and those motions, sights, smells mean so much and help me get closer to G-d as I pray for my family and any who need it.
