In 1956, during the Order’s worldwide expansion in the wake of World War II, Pope Pius XII encouraged the Order’s leadership to form a new class of Knights and Dames “in Obedience” to follow fervently a path to Christian perfection in the spirit of the Order’s charism and to assist in carrying out functions previously exercised exclusively by the Knights of Justice, the Order’s Professed Members.
The Order’s 1961 Constitutional Charter formally created a class of Knights and Dames in Obedience who, through a solemn Promise of Obedience, respond to this vocation within the Order.
The Subpriory of Our Lady of Philermo is comprised of Knights of Justice, Knights in Obedience, and Dames in Obedience who are also members of the Western Association USA.
Formed in 2001, it was the first Subpriory established outside of Europe. Worldwide, the Order has six Grand Priories (each led by a Prior) and six Subpriories (each led by a Regent).
Today, it is one of two Subpriories in the Americas (the other being the Subpriory of Our Lady of Lourdes based in New York) and one of three outside of Europe (the third being the Australian Subpriory of The Immaculate Conception based in Melbourne).
