Did God changed Sabbath from Saturday to Sunday

Since the Bible from Genesis to Revelation recognizes only the Saturday Sabbath as the weekly day of rest, then how did the practice of Sunday worship come about? What is its origin? Some Christians feel that Sunday should be observed to commemorate the resurrection, but where in the Bible did Jesus or the apostles make such a statement? Who sanctioned the replacement of the Sabbath with Sunday or claims to have done so? If it was God, then why isn't it in the Bible, and if was not God then there is a problem. Christ says: "Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven." Matthew 5:19 So does the Bible allow for Gods Law to be changed by men or their "tradition", I don't think so. We find Christ saying: Mark 7:7 Howbeit in vain do they worship me, teaching for doctrines the commandments of men. Sunday-keeping was a Roman Catholic invention from paganism that achieved universality because of the authority of the Roman church. Anti-Jewish sentiments were strong in Rome, and Gentiles became prominent in the church there. Because of the friction that arose to separate Christians from the Jews and their Sabbath, Gentile Christians adopted the venerable day of the Sun from pagan sun worship as a substitute. Although the church in Rome influence some areas of the empire, it was not able to change long-standing Sabbath worship in all parts, especially in the East where those beliefs were based on the true apostolic practice The Roman Catholic created their own day of worship, from Pagan Festivals and the Pagan Religion before Christianity, and tried to cover it with reference to "tradtions", but it was pagan traditions that it was referring to. "The Church made a sacred day of Sunday ï¿½ largely because it was the weekly festival of the sun; for it was a definite Christian policy to take over the pagan festivals endeared to the people by tradition, and to give them a Christian significance.R03;" Source: Arthur Weigall, The Paganism in Our Christianity, p. 145. Copyright 1928 by G. p. Putnamï¿½s Sons, New York. "The church took the pagan philosophy and made it the buckler of faith against the heathen. She took the pagan, Roman Pantheon, temple of all the gods, and made it sacred to all the martyrs; so it stands to this day. She took the pagan Sunday and made it the Christian Sunday. She took the pagan Easter and made it the feast we celebrate during this season.R03; Sunday and Easter day are, if we consider their derivation, much the same. In truth, all Sundays are Sundays only because they are a weekly, partial recurrence of Easter day. The pagan Sunday was, in a manner, an unconscious preparation for Easter day. The Sun was a foremost god with heathendom. Balder the beautiful, the White God, the old Scandinavians called him. The sun has worshippers at this hour in Persia and other lands. "Some of you," says Carlyle, "may remember that fancy of Plato's. A man is kept in some dark, underground cave from childhood till maturity; then suddenly is carried to the upper airs. For the first time he sees the sun shining in its splendor overhead. He must fall down, says Plato, and adore it." There is, in truth, something royal, kingly about the sun, making it a fit emblem of Jesus, the Sun of Justice. Hence the church in these countries would seem to have said, "Keep that old pagan name. It shall remain consecrated, sanctified." And thus the pagan Sunday, dedicated to Balder, became the Christian Sunday, sacred to Jesus. The sun is a fitting emblem of Jesus. The Fathers often compared Jesus to the sun; as they compared Mary to the moon, the beautiful moon, the beautiful Mary, shedding her mild, beneficent light on the darkness and the night of this world - not light of her own; no Catholic says this; but - light reflected from the sun, Jesus.R03;" Source: PASCHALE GAUDIUM, by Willliam L.

"All things whatsoever that were prescribed for the [Bible] Sabbath, we have transferred them to the Lord's day, as being more authoritative and more highly regarded and first in rank, and more honorable than the Jewish Sabbath."--Bishop Eusebius, quoted in J.P. Migne, "Patrologie," p. 23, 1169-1172. [Eusebius of Caesarea was a high-ranking Catholic leader during Constantine's lifetime.] "These Gentile Christians of Rome and Alexandria began calling the first day of the week 'the Lord's day.' This was not difficult for the pagans of the Roman Empire who were steeped in sun worship to accept, because they [the pagans] referred to their sun-god as their 'Lord.' "--EM. Chalmers, "How Sunday Came Into the Christian Church," p. 3. "What began, however, as a pagan ordinance, ended as a Christian regulation; and a long series of imperial decrees, during the fourth, fifth, and sixth centuries, enjoined with increasing stringency abstinence from labor on Sunday."--Huttan Webster, "Rest Days," pp. 122-123, 210. In both Old and New Testament there is not a shadow of variation in the doctrine of the Sabbath. The seventh day, Saturday, is the only day ever designated by the term Sabbath in the entire Bible. So Jesus or the Apostles did not change the day of worship from Saturday to Sunday the first day of the week?
