Today we are considerably more casual and careless about observing the Sabbath and we are poorer, both religiously and humanly, because of this. Much of our tiredness and sense of being over-burdened comes from not having a regular Sabbath in our lives.
Remember to keep holy the Sabbath day. Until recently it was more clear that this is a commandment, not simply a lifestyle suggestion. Sabbath, until recent generations, was a day where ordinary life and ordinary activity were supplanted by different sense of time and activity. - Fr Ron Rolheiser, ronrolheiser.com
