For ye were as sheep going astray; but are now returned unto the Shepherd and Bishop of your souls.
1 Peter 2:25
Christians must not judaize by resting on the Sabbath, but must work on that day, rather honouring the Lord's Day; and, if they can, resting then as Christians. But if any shall be found to be judaizers, let them be anathema from Christ.
