 In 1833 came the first members of what would become Errico's religious order known as the Missionari dei Sacri Cuori di Gesù e Maria.On 8 February 1834 the group signed a petition addressed to Cardinal Filippo Giudice Caracciolo asking for them to be considered a religious congregation but those priests grew impatient and left Errico alone to manage on his own.This small group received diocesan support on 14 March 1836 while the Rome-based Sacred Consistorial Congregation also provided approval on 30 June 1838.
