Texas York Rite Research Center
The The Grand Chapter of the State of New York, Royal Arch Masons has warranted the Thomas Smith Webb Chapter For Royal Arch Research as the first Royal Arch Chapter to be solely devoted to Royal Arch research and scholarship.
The Massachusetts Chapter of Research was instituted on September 22, 1973 when M.E. Lane Ellison Wheaton, Grand High Priest of the Grand Royal Arch Chapter of Massachusetts issued a Charter empowering it to work.
The purpose of this chapter is to diffuse Masonic light and knowledge; and to promote, encourage and conduct Capitular Masonic research. It does not confer any of the Capitular degrees regularly conferred in a duly constituted chapter; but concerns itself with nothing other than it's purpose of Capitular Masonic research.
