A Christian Caveat To the Old and New Sabbatarians. Or, A Vindication of our Gospel-Festivals. Wherein is held forth, I. That The Feast of Christs Nativity is grounded upon the Scriptures; was Observed in the pure, ancient, Apostolique times, and is approved by all Reformed Churches. II. That Christ was born on the 25 day of December; and all Objections to the contrary refuted. III. That the keeping holy the Lords-Day was appointed by the Christi- an Church; and that the Morality, and Divine Institution of the Lords- Day are meer fictions. IV. That the Day of Christs Nativity, the Day of his Passion, and the like, have equall Authority, equall Antiquity, equall right to be obser- ved as the Lords Day; and that to work on those Dayes is equally sinful. V. That the Observation of the Sabbath Day is abolished in Christ; and that to call the Lords Day the Sabbath, is senseless, Jewish, unchristian, unwarrantable.
