There are scads of people under the banner of 'Christianity' that go to churches and are taught that the 10 Commandments are no longer part of the doctrine of believers. The Commandments, also known as 'The Law' is somehow nailed to the cross; or done away with by Jesus himself.
The case is usually made because ministers somehow rationalize that the Commandments being given to Moses, and thereby the children of Israel were somehow exclusively to one group of people.
Our God is Not a respecter of persons! (Acts 10:34)!
The commandments as they were proposed to The children of Israel was the same Commandments of God that determined the 'Sons of God' from Adam down to Abraham, Issac, Jacob, and Jacob's (aka Israel) 12 sons.
LET IT BE KNOWN: The Biblical definition of sin, is; the transgression of the Law. (1John 3:4)
