The Abbey-Principality of San Luigi has established fraternal relations with the Ordine Militare e Religioso dei Cavalieri di Cristo (Religious and Military Order of the Knights of Christ, abbreviated as OMRCC) in Italy. The OMRCC is a modern Order inspired by the historic Templar tradition, and is organized as a Public Association of the Faithful of the Roman Catholic Church. It is an active charitable body with numerous humanitarian projects worldwide and welcomes donations from those wishing to support its work.
The Grand Vicar International of the OMRCC, H.E. Frà Federico Righi, has been admitted as a Knight Officer of the Order of the Crown of Thorns by San Luigi Grand Prior for Continental Europe H.E. Dr. Norbert Wójtowicz.
The Prince-Abbot and the Grand Prior for Continental Europe have accepted Honorary Brotherhood in the OMRCC and Academic Membership “ad honorem” in the associated Accademia Templare di San Bernardo da Chiaravalle, which has been established for the purpose of historical research into the Templar tradition and St. Bernard of Clairvaux.
The connexion of the Abbey-Principality of San Luigi with modern Templars today reflects the legendary foundation of the Order of the Crown of Thorns as a continuation of the Templar legacy, as well as the ecclesiastical succession of the Prince-Abbot from Bernard Fabré-Palaprat, founder of the Ordre du Temple in 1804, which is commemorated in the Ecclesia Apostolica Divinorum Mysteriorum within the Abbey-Principality.
