None of the brothers must lay claim to anything as his own, but you are to possess everything in common; and each is to receive from the prior — that is from the brother he appoints for the purpose — whatever befits his age and needs.
Saint Albert of Jerusalem
The Carmelite Rule, Chapter 12
In 1229 Pope Gregory IX forbade the Carmelites to possess properties, houses, land, or income of any type so that they might be less distracted by such concerns and more easily devoted to the life of contemplation. He confirmed Pope Honorius III’s approval of the Rule of Carmel with the Brief Ex Officii Nostri.
