The interpretation of Old Testament laws, including those about the Sabbath, varies among Christians.
Some Christians believe that these laws are no longer binding due to the New Testament teachings about grace and the fulfillment of the law through Jesus Christ. They would not support killing someone for working on the Sabbath.
Other Christians may see value in the principles behind the Sabbath laws but interpret them in a modern context, focusing on rest and worship rather than strict adherence to the original penalties.
There are very few, if any, Christians who would advocate for killing someone for working on the Sabbath today. This is because the overwhelming consensus among Christians is that the New Testament teachings of love, forgiveness, and grace supersede the Old Testament laws regarding capital punishment for Sabbath violations.
It is important to understand the diversity of Christian beliefs and interpretations when considering this topic.
