The bishop approved of this project and instructed Habets to write the foundational documents for a new order. The Rule drawn up based on that of the Jesuits in 1832 and on 8 September 1833 - in the Carmelite church next to their school - Haze was allowed to profess permanent religious vows while taking the religious name of "Marie Thérèse of the Sacred Heart of Jesus" as was Ferdinande under the name of "Aloysia" and two other companions. Two of their companions professed initial vows and the remainder of the group began a formal novitiate. Thus the congregation was born and she was chosen its first Superior (in this post until her death). Haze died in 1876; her remains were later housed in the chapel at the order's motherhouse on 21 April 1993 after the place was renovated to accommodate this transferal. In 2005 her order had 857 religious in 115 houses in nations such as Pakistan and the United Kingdom. It received the papal decree of praise from Pope Gregory XVI on 1 October 1845 and full pontifical approval from Pope Pius XII on 9 May 1951. The beatification process opened in Belgium in a local investigative process that spanned from 1902 until 1905 while the formal introduction came under Pope Pius X on 13 December 1911 in which she was titled as a Servant of God. Her spiritual writings received theological approval on 23 February 1910 while the Congregation for Rites validated the informative process on 26 June 1923 in Rome. An antepreparatory committee approved the cause on 1 July 1937 as did the preparatory one on 30 May 1939 and the general one on 10 December 1940. Pope Pius XII titled her as Venerable on 9 February 1941 after confirming her heroic virtue. Pope John Paul II beatified Haze on 21 April 1991.
