How come that most of Christianity worships on Sundays instead?
A. Christianity became perverted with paganism and in control of the Roman Empire which ruled the world at that time. Doctors of Rome such as Justin Martyr corrupted the purity of the New Testament teachings with doctrines of Mytra, the Roman state religion. He replaced the Lords supper with the Eucharist and with hatred for all Jewish substituted Saturday the Seventh-day Sabbath with Sunday. Emperor Constantine the Great in 325 A.D. made it into law. He never called it the Sabbath, but the venerable day of the sun instead. That title still belongs to that day to this day, namely Sunday or day of the sun and not the Son. The Sabbath belongs to the Son of GOD, the Lord of the genuine Lords day.
