First a little history: France has been historically dominated by the Catholic Church. There was a brief time during the Reformation, when French Calvinists (called Huguenots) attempted to become dominant. Protestantism was basically illegal, until just before the French Revolution (which was basically atheistic). After the end of the Revolution, modernism was in full swing, and it is hard to imagine religion of any kind having much hold.
Which brings us to a bizarre law from 1906 which "forbids Sunday trading in all but the largest cities".
Even more bizarre is the opposition to lifting the ban, although it is stemming from labor unions and socialists for economic and political reasons, rather than religious.
Two questions then:
- Are Christians required to keep the Sabbath?
- Is Sunday the Sabbath day?
Okay, so why do I go to church on Sunday - and why am I not in an Adventist church? - essentially, the first question.
The Sabbath is a shadow, a sign pointing forward.
Jesus Christ is our rest.
I "keep the Sabbath" by keeping in Jesus Christ.
