URIM AND THUMMIM
Light and perfection, among the ancient Hebrews, a certain oracular manner of consulting God, which was done by the high priest, dressed in his robes, and having on his pectoral, or breast-plate. There have been a variety of opinions respecting the Urim and Thummim, and after all we cannot determine what they were. The use made of them was, to consult God in difficult cases relating to the whole state of Israel, and sometimes in cases relating to the king, the sanhedrim, the general of the army, or some other great personage.
Charles Buck (1771-1815) was an English Independent minister, best known for the publication of his “Theological Dictionary”. According to the “Dictionary of National Biography”, a Particular Baptist minister named John C. Ryland (1723-1792) assisted Buck by writing many of the articles for the aforementioned publication. One may conclude, based not only Buck’s admiration for his friend Ryland, but also on the entries in his Theological Dictionary, that he stood head and shoulders with the High-Calvinists of his day.
