It was The Church (NOT God) who abolished the Sabbath in the mid part of the fourth century – See church documents from the ecumenical councils convened by Emperor Constantine, specifically, Council of Laodicea document, Canon number 29. https://www.ccel.org/ccel/schaff/npnf214.viii.vii.iii.xliii.html. This canon orders that the Sabbath is a Jewish holy day and therefore the church should have no part in it. The Sabbath was ended and a new practice of communal worship was instituted on the first day, an already established day of worship for the Sun God. This was now called "The Lord's Day."
(Additionally, Canons 37 and 38 made it unlawful to receive food portions from or participate in a Jewish Feast, or to receive unleavend from a Jew, thus becoming "partiakers in their impiety.")
