The Most Meritorious Order of the Holy Spirit confers a companion auxiliary membership to the Holy Orthodox Order of Saint George the Great Martyr. Both Orders share the same administrative hierarchy and Grand Magistry without Separation.
The Order of the Holy Spirit is open to Orthodox and non-Orthodox, Trinitarian Christians who profess the Nicene-Constantinopolitan Creed of 381 AD and who support the works and activities of the Holy Orthodox Order of Saint George the Great Martyr. Auxiliary membership is either by application or by bestowal of the Grand Knight.
Non-Orthodox Christians who apply for auxiliary membership in the Order of the Holy Spirit form a distinct class, and become non-voting, companion members of the Order of Saint George the Great Martyr and may partake in the full social life and activities of the Order without restriction. Applications for auxiliary membership do not require consultation with the First Hierarch of the Russian Orthodox Church Outside of Russia.
The Grand Knight, as the temporal fons honorum (fount of honor) within the Holy Orthodox Order of Saint George the Great Martyr, and by virtue of his position as temporal head, has the exclusive right of conferring the Most Meritorious Order of the Holy Spirit as a Decoration of Merit. This honor is reserved to express the Grand Knight’s appreciation of a person’s extraordinary service to the Orthodox Church and to the Order of Saint George the Great Martyr. This means that an individual had assumed a responsibility or displayed an ability considerably greater than might have been expected of him or her; that an individual had performed activities in an excellent manner which have been of great benefit to the greater Orthodox Christian World.
The Grand Knight needs to consult with the First Hierarch of the Russian Orthodox Church Outside of Russia before officially bestowing the Decoration of Merit upon those who are not canonical Orthodox Christians, and who fall outside of the Orthodox Church. In this case, the brevet (certificate) of appointment to the Most Meritorious Order of the Holy Spirit is signed by both the Grand Knight and by the First Hierarch and/or his Clerical Representative.
The insignia of the Most Meritorious Order of the Holy Spirit, like the medals of the Holy Orthodox Order of Saint George the Great Martyr, are to be worn with great care and with appropriate and suitable dress. The Order’s protocol for wearing medals should always be observed and followed by anyone who has been given the honor and privilege to receive them. Individuals who have been awarded the medals of the Order of Saint George the Great Martyr or of the Order of the Holy Spirit should wear their insignia on the following occasions:
Official receptions hosted by either His Most Excellency the Grand Knight or by his spouse
Official receptions hosted by the Prior of a Grand Priory or by their spouse
