You asked if I celebrate the sabbath, I said yes.Since you cannot defend your position from Scripture you want to forget about the tithe altogether and focus on the Sabbath.
At this point, I really do not care where you want to go. My brain is fried. It has nothing to do with you though.
But since all you have to offer at this point is ad hominems and rabbit trails, then I will take the hint and assume that the debate is over. No need to beat a dead horse. Hopefully your are giving more than 10%, but if not, that's between you and the Lord.
Now do you believe that the Old Testament is authoritative for faith and practice or merely a good story book from which we can gain good allegorical truths?
I answered your question, I think its your turn to answer mine.
