Pope Francis, the current head of that organization, the Roman Catholic Papacy, is following in the footsteps of his predecessors in urging the world to follow his church's tradition of Sunday sacredness thus rejecting the Sabbath of Creator God. And almost all the world is obeying the call (Revelation 13:3).
He wrote in his recent encyclical, "On Sunday, our participation in the Eucharist has special importance. Sunday, like the Jewish Sabbath, is meant to be a day which heals our relationships with God, with ourselves, with others and with the world. Sunday is the day of the Resurrection, the "first day" of the new creation, whose first fruits are the Lord's risen humanity, the pledge of the final transfiguration of all created reality. It also proclaims "man's eternal rest in God".(LAUDATO SI', Section 168).
But this is totally contrary to the God of Creation.
