Those who believe we are relieved of Moses' Law should commit adultery, lie, and murder. If not was only one commandment nailed while nine others remain in force? All denominations teaching that Yeshua nailed the Law should not accept tithes. Tithing was established under the Levitical priesthood. If your church teaches OT rules only apply to Jews, tithing falls into that category too. Yeshua entered the synagogue on the Sabbath (Luk 4:16,6:6, 13:10). Paul customerily entered the synagogue Sabbath(Acts 13:14, 27,42,44,15:21,16:13, 17:2). Hence he writes in Heb 4:9: So there remains a Shabbat-keeping for God's people.Gentiles kept the Sabbath after the cross (Acts 18:4) hence we are still required to observe the 7th-day Sabbath.
