“I also do not go to any Church who calls Sunday the Sabbath.”
I was with you until here - can you expand on that one?
Gen 2
2 Thus the heavens and the earth were finished, and all the host of them.
2 And on the seventh day God finished his work that he had done, and he rested on the seventh day from all his work that he had done.
3 So God blessed the seventh day and made it holy, because on it God rested from all his work that he had done in creation.
Exodus 20
For in six days the Lord made heaven and earth, the sea, and all that is in them, and rested on the seventh day. Therefore the Lord blessed the Sabbath day and made it holy.
