Beta has no desire to be obediant to the OT strictures. She wishes to pick and choose which ones to follow and after some conversing with her it is only OT Sabbath that she follows. All the other 613 OT commands she ignores. As for the doctrine she believes, that is somewhat of mystery.
I have met people like that. I cannot follow their system of belief at all.
As to restoring Sabbath to Saturday, I believe it is a true move of God. However, it has to be restored PROPERLY, meaning that the distinction that it is a covenant sign of the Israelites (both natural and prostelites) and not incumbant on the gentile believers has to be clearly understood, and that applies to both the Saturday sabbath keepers and the Sunday keepers.
As to the rest of the 613 Mosaic commands, analysis needs to be made on how and whether each command can be worked out in a New Covenant setting, and by WHOM.
Actually, our Rabbi and the director of our brotherhood of congregations are working together on that very book. They are posting chapters as they become available:
