Overview

The Grande Loge traditionnelle et symbolique Opéra (GLTSO) is a French masonic obedience founded in 1958 following a split from the Grande Loge nationale française (GLNF). It is exclusively masculine and belongs to traditional Freemasonry, and it is a member of the Confédération des grandes loges unies d'Europe. Its name derives from the address of its original headquarters on avenue de l'Opéra in Paris. The GLTSO describes itself as the fourth French masculine obedience, with around 4,200 members and 250 lodges in metropolitan France, overseas territories and Europe. It offers its members an open and tolerant belief in a transcendent principle called the Great Architect of the Universe. Its stated values include spiritual and moral development, fraternity, tolerance, benevolence and respect for commitments. The GLTSO practises six rites, with the Rectified Scottish Rite as its founding and official rite. It is active in philanthropy through an endowment fund and fundraising galas that support humanitarian associations aiding vulnerable populations and children in difficulty. It publishes the quarterly review Epistolae Latomorum and other publications linked to its research lodge and rites.

History

The Grande Loge traditionnelle et symbolique Opéra (GLTSO) was founded in 1958 when seven lodges, including the "Centre des amis", separated from the Grande Loge nationale française (GLNF) to form the "Grande Loge nationale française - Opéra" (GLNF-Opéra). The name referred to the address of its headquarters on avenue de l'Opéra in Paris. Two reasons motivated the split: the strong influence of English brethren on the GLNF (about 25% of its members) and the desire to establish fraternal relations with other obediences. The obedience was also created to be a conservatory of the Rectified Scottish Rite, founded in the 18th century by Jean-Baptiste Willermoz and revived in France in 1910 by Camille Savoire and Édouard de Ribaucourt. Three years after its foundation, the new obedience was, along with other masonic obediences, one of the founders of the Centre de liaison et d'information des puissances maçonniques signataires de l'appel de Strasbourg (CLIPSAS), an organisation it no longer belongs to. In 1982, the "Grande Loge nationale française - Opéra" changed its name to "Grande Loge traditionnelle et symbolique Opéra" (GLTSO) to avoid confusion and to better distinguish itself from the original GLNF (known as "Bineau") and from the Loge nationale française founded in 1968. The GLTSO is the third or fourth French masculine obedience, with around 4,200 to 4,500 members and nearly 250 to 300 lodges in France and worldwide. It has lodges in many French cities such as Besançon, Nantes (three lodges), Agde and Le Mans. In addition to its headquarters in Levallois-Perret, it has a temple in Villeurbanne and another in Saint-André-lez-Lille. In 2009, it was estimated that 20% of its members were in several African countries, the French overseas territories, Belgium, Italy, Spain and Thailand. It is at the origin of the Grande Loge traditionnelle et symbolique de Madagascar and the Grande Loge traditionnelle et symbolique d'Afrique. The GLTSO engages in active philanthropy through its endowment fund and by organising galas to raise funds and distribute them directly or through several humanitarian associations that provide care and relief to vulnerable populations and children in difficulty. The Rectified Scottish Rite is its founding and official rite. It also practises the Emulation-style English Rite, the Traditional French Rite, the Ancient and Accepted Scottish Rite, the Standard Scottish Rite and the York Rite. Every quarter, it publishes the review Epistolae Latomorum. Once a year, its research lodge "Héritage n°2" publishes a notebook devoted to Jean-Baptiste Willermoz and more broadly to the Rectified Scottish Rite. Members who practise the Traditional French Rite also publish the review Tradition(s).
