Covenant Confusion-Law and Grace

QUESTION RECEIVED:

What is the purpose of book of the covenant that was placed alongsider the Ark? I understood it was an expansion of the Decalogue and that the Decalogues is a summary of the book of the covenant? SDAdventists are telling me that the Ten Commandments WAS NOT the old covenant, and, therefore, I must keep the 7th day sabbath law today.


MY ANSWER:

The "Book of The Covenant" or "Book of Law" is the Ten Commandants and commands and rules they the Hebrews under Moses were to follow. The Decalogue is the Ten Commandments.
