Dehon's focus in his ecclesial life was to express his closeness with workers but above all wished to foster and promote a devotion to the Sacred Heart of Jesus. It also became his mission to establish an order that would be dedicated to this task as well as to working in the foreign and diocesan missions in France and abroad. But impediments caused the order's dissolution though was later reformed and reestablished with Dehon assuming its leadership until his death.
