Some people think the only "proper" way to live is nonstop working.
I don't think there is any. Muslims have Friday Sabbath.
The Devil did know that Jesus is the Messiah. But that is exactly what he is trying to get nonbelievers to think.
YES, you just need to believe and then for the nonbelievers think it's not true.
There is no such commandment. The reason for this notion is a tradition that started with the commandment "Keep Holy the Sabbath Day." It was interpreted to mean that people should not labor gainfully on the Sabbath. Sunday is, however, not the Sabbath. The fact that Sunday is the holy day of the week is a Christian tradition.
I think the word you might be asking of is "unnecessary".
i think nit is Sunday
The Old Testament stated to remember the sabbath and keep it holy. Jesus said that someone could work on the sabbath if they are doing good. Examples might be volunteering for charity, or helping orphans and widows, or feeding the poor.
rest and worship (i think)
No, Christians do not think that it is OK to kill people for working on the Sabbath as it says in the Old Testament of the Bible.
Puritans believed in strict observance of the Sabbath day, considering it a sacred time for rest, worship, and reflection. They avoided unnecessary work and activities, focusing on prayer and attending religious services. Breaking Sabbath laws was often punished within Puritan communities.
