when was the sabbath day changed from saturday to sunday
Sabbath in Christianity Early Christians continued to pray and rest on the seventh day.[9] By the 2nd century AD some Christians also observed Sunday, the day of the week on which Jesus had risen from the dead and on which the Holy Spirit had come to the apostles.[9] Paul and the Christians of Troas, for example, gathered on Sunday "to break bread," [10] Soon Christians were observing only Sunday and not the Sabbath.[9] Patristic writings attest that by the second century, it had become commonplace to celebrate the Eucharist in a corporate day of worship on the first day.[11] A Church Father, Eusebius, stated that for Christians, "the sabbath had been transferred to Sunday".[12]
Biblical Sabbath Observation and remembrance of Sabbath is one of the Ten Commandments (the fourth in the original Jewish, the Eastern Orthodox, and most Protestant traditions, the third in Roman Catholic and Lutheran traditions), sometimes referred to individually as the Sabbath Commandment. Most people who observe Biblical Sabbath regard it as having been made for man (Mark. 2:27) at Creation (Ex. 20:8–11), and instituted as a perpetual covenant for the people of Israel (Ex. 31:13-17, Ex. 23:12, Deut. 5:13-14), a rule that also applies to proselytes, and a sign respecting two events: the seventh day, during which God rested after having completed Creation in six days (Gen. 2:2-3, Ex. 20:8-11), and God's deliverance of the Israelites from Egypt (Deut. 5:12-15).
