Editing Congregation of Holy Cross (section)

===The Association of Holy Cross===
In 1837, Moreau made the decision to combine his two communities into one society so that the priests and brothers could share resources and ministries in common.<ref name="chc" /> On March 1, 1837, the priests and brothers gathered in the church of [[Notre Dame de Sainte Croix, Le Mans|Notre-Dame de Sainte-Croix, Le Mans]], in the Sainte-Croix district of [[Le Mans]] to sign the Fundamental Act of Union which legally joined them into one association. This new group took on the name of where they met and became the Association of Holy Cross. Initially Holy Cross was a diocesan group and so they primarily served in whatever capacity the bishop asked of them. In 1840 this changed when Moreau received a request to send a delegation from his society to [[Algeria]] with the purpose of establishing schools and a seminary. It was at this point that Moreau shifted the focus of Holy Cross and after the first missionaries left in April 1840 the association took on the identity of a [[religious institute]]. On August 15, 1840, Moreau and four others became the first professed religious in the Association of Holy Cross. As part of his plan to form this religious institute, Moreau also brought together the first group of women who would become the Marianites of Holy Cross.{{Cn|date=April 2025}}

In 1841, he sent a group to the [[United States]], establishing the first Holy Cross institution in North America at [[University of Notre Dame|Notre Dame]] in [[Indiana]]. The institute expanded further by establishing missions in [[Canada]] in 1847 and in [[Bangladesh|East Bengal]] in 1852.<ref name="chc" />

This association of priests, brothers, and sisters, would continue in roughly the same form until May 13, 1857, when [[Pope Pius IX]] approved the first constitutions of the priests and brothers. From that point on the Association officially became the Congregation of Holy Cross. Doubting the propriety of a mixed congregation of men and women, Rome separated the women into an independent community at that time. Moreau, in his role as their founder, continued to work for Rome's approval of the sisters' constitution. In 1865, Rome approved the constitutions of the [[Marianites of Holy Cross]], granting them the status of an Apostolic congregation.{{Cn|date=April 2025}}
