who changed the day of worship from saturday to sunday
Sabbath in Christianity Early Christians continued to pray and rest on the seventh day.[10] 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.[10] Paul and the Christians of Troas, for example, gathered on Sunday "to break bread," [11] Soon some Christians were observing only Sunday and not the Sabbath.[10] 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.[12] A Church Father, Eusebius, stated that for Christians, "the sabbath had been transferred to Sunday".[13]
