Every once in a while I come across someone who attempts to use Acts 15 as justification for not keeping Torah. But, when read in context, the bottom line is: Acts 15 is referring to man-made laws and NOT the Torah itself!
Why would ANY part of the Torah not pertain to ALL who have accepted YHWH as their ELOHIM? In Numbers 15:13-16 ADONAI said FOUR TIMES in a row, that ALL who accept Him are to do exactly as His people do; that there is no difference between His natural and adopted children, once someone accepts Him as their God.
And Galatians 3:28 tells us, "There is neither Jew nor Gentile, neither slave nor free, nor is there male and female, for you are all ONE in Messiah."
As "one" doesn't that imply "same God. same rules?" WHY would there be different rules? Did YHWH only expect Jews to be holy/set apart?
It is imperative to remember that once Gentiles accept the God of Abraham, Isaac and Jacob, they are no longer considered to be "Gentiles: as they become HEBREWS (like the pagan Chaldean Abraham did in Genesis 12). "Hebrew" in the Hebrew language means "to cross over".... If you've "crossed over" then shouldn't you begin to follow His Rules? If you don't, WHOM are you worshiping?
For more on this issue, I recommend reading our article, Acts 15: Does Torah pertain to Christians?
