Let me clarify. I was not implying that attending mass on Sunday was scientific. What I was stating, as a retired “Rocket Scientist”, that there are approximately 24 hours in a day. So, “tongue-in-cheek” I was asking how we can fulfill our “Sunday” obligation over a 24 hour period.
I struggle with what we call history. As time goes on the real reason why things are done both from a religious, as well as from a secular point of view, are many times lost. How many times do we hear “separation of Church and State”. Than someone argues that was NOT what our founding fathers meant!
I think all the points made are valid, but what I was pointing out was, when I was younger, Now almost 70, We only had Mass on Sunday. So 12:00 midnight to 11:59 P.M. was considered Sunday. Then the Bishops, belonging at that time, the National Conference of Catholic Bishops, decided to make it easier to fulfill the Sunday obligation by copying our Jewish friends and stating that actually we can consider Sunday starting at sundown on Saturday. Not thinking, if that is the case, about sundown on Sunday ending the day.
