That said, yes, we do have our own traditions. On Shabbat we light the candles, do Kiddush, and break bread. God does not command these things to be done on Sabbath, but they do not go contrary to His word either. :-)
Traditions are just that; man’s creations. Scripture is God’s word to man. It is the readers duty to prayerfully interpret. (For you Catholics there is a “tradition” that St. Peter died in South Russia.) I don’t insist it is true but it does exist thus showing the worth of “traditions.”
On what calendar day is the Sabbath, may I ask?
