George Preca was a Maltese Catholic priest born in 1880 in Valletta who dedicated his life to religious education and pastoral care. A member of the Third Order of Carmelites, he established the Society of Christian Doctrine, locally known as M.U.S.E.U.M., to teach the catechism to the people. Despite facing scrutiny from certain clergy regarding his methods, his work was eventually validated by the Church. He is recognized for his extensive writings in the Maltese language and for composing five mysteries of the Rosary known as the Mysteries of Light.
