They have rules reflecting the spirit of the corresponding order but adapted to life in the world; hence, the offices to be read are short and the fasts are mild. The promises made on joining are not vows; their purpose is the sanctification of the members. Secular members of third orders (i.e., those who live in the world) may be priests or laymen; there are also tertiaries who live in communities, the regular tertiaries.
