Ahiman Rezon - The title given by Dermott to the Book of Constitutions of the Grand Lodge of Ancient Freemasons in England, which was established about the middle of the eighteenth century in opposition to the legitimate Grand Lodge and its adherents who were called the Moderns, and whose code of laws was contained in Anderson's work known as the Book of Constitutions. Many attempts have been made to explain the significance of this title; thus according to Doctor Mackey, it is derived from three Hebrew words, zhiln, meaning brothers; ..manah, to appoint, or to select in the sense of being placed in a peculiar class (see Isaiah liii, 12), and ..ratzon, the will, pleasure, or meaning; and hence the combination of the three words in the title, Ahiman Rezon, signifies the will of selected Brethren- the law of a class or society of men who are chosen or selected from the rest of the world as Brethren.
