Fine. But you're not observing Sabbath.
Genesis 2 1 Thus the heavens and the earth were finished, and all the host of them. 2 And on the seventh day God ended his work which he had made; and he rested on the seventh day from all his work which he had made. 3 And God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made.
And so now the Catholic church decides everyone should rest on the 1st day. God made the 7th day the Sabbath no reason for humans to change it.
Yeah, unless we want to celebrate the Resurrection instead of the Old Covenant. We consider that to be important.
"No reason," he says.
