SUNDAY SERVICES
Early believers kept Saturday as the Sabbath until March 7, 321 CE when Pope Constantine passed a law requiring believers to worship on Sunday, the day the pagans worshipped the sun-god.
Believers still kept Saturday as the Sabbath until another law was passed eleven years later.
This law signed into decree by Pope Constantine forbid believers to worship on the Sabbath (Saturday) and it was punishable by death by the Catholic Church.
Many believers were burned to death by the Catholic Church for keeping the Sabbath.
