Albert Mackey

“ I am disposed to adopt a middle course, and to define the Landmarks of Masonry to be, all those usages and customs of the craft--whether ritual or legislative--whether they relate to forms and ceremonies, or to the organization of the society--which have existed from time immemorial, and the alteration or abolition of which would materially affect the distinctive character of the institution or destroy its identity. ”

“ These, although not of such paramount importance and universal acceptation as the Old Charges and the Thirty-nine Regulations, are, nevertheless, of great value as the means of settling many disputed questions, by showing what was the law and usage of the fraternity at the times in which they were adopted.
Soon after the publication of the edition of 1769 of the Book of Constitutions, the Grand Lodges of America began to separate from their English parent and to organize independent jurisdictions. ”

“ Some suppose them to be constituted of all the rules and regulations which were in existence anterior to the revival of Masonry in 1717, and which were confirmed and adopted by the Grand Lodge of England at that time. Others, more stringent in their definition, restrict them to the modes of recognition in use among the fraternity. ”
