Hamilton Sovereign Chapter of Rose Croix confers the 15th to 18th degrees inclusive. The 15th and 16th degrees relate to the rebuilding of the Second Temple of Zerubbabel. The 17th degree is an approach to, and the 18th degree a recognition of, the Christian ethics in universal terms, thus assisting in the building, in our hearts, of the Third Temple, not made with hands. The 18th degree is supplemented by the beautiful Maundy Thursday and Easter ceremonies. The 15th and 18th degrees are obligatory.
