The special aim of this congregation is the sanctification of its members in the religious state by the exercise of works of charity, which in the spirit of its founder embrace every phase of moral and physical suffering and want. They consist in a special manner in tending the sick, in sheltering poor workmen, in the care of the aged and of people with a mental illness, in instructing and bringing up orphan children and young people. The services delivered by the Brothers of Charity were appreciated by the people and Government of Belgium, and in a short time they developed and expanded.
