Christians compromise with pagan “sun worship” practices and adopt “Sunday”
“Before the coming of Christ, all the Eastern nations performed divine worship with their faces turned to that part of the heavens where the sun displays his rising beams ... The Christian converts ... retained the ancient and universal custom of worshiping toward the east, which sprang from it.” Mosheim’s Ecclesiastical History, century II, part II, ch. IV, par. 7.
“Sunday (Dies Solis, of the Roman calendar; ‘day of the sun,’ because it was dedicated to the sun), the first day of the week, was adopted by the early Christians as a day of worship.” Schaff-Herzog Encyclopaedia of Religious Knowledge, Art. “Sunday.”
“We all gather on the day of the sun ... on this same day Jesus Christ our Savior rose from the dead.” From the “Church Father,” St. Justin. Quoted in the New Official Catholic Catechism (1994), p. 524.
Following in the steps of ancient Israel, Christians in the 1st (latter part), 2nd and 3rd centuries “hid their eyes” from God’s Sabbaths (see Ezekiel 22:26) and adopted pagan traditions associated with sun worship.
