You mean like all those "good" Catholics who go to mass on Saturday evening so they can sleep in or go golfing Sunday morning rather than going to church?
I think the Catholic church may have allowed that practice to ensure that those who work on Sundays ie:Police, fire personnel, merchants,institutional personnel, etc could still fulfill their Sunday obligations.
I'm certain that Christ can figure it out and let's face it, attending Mass ANYTIME is of extraordinary benefit to ANYONE.
