Bula
With the Papal bull "Pie postulatio voluntatis" dated 15 February 1113, Pope Paschal II approved the foundation of the Hospital and placed it under the aegis of the Holy See, granting it the right to freely elect its superiors without interference from other secular or religious authorities. By virtue of the Papal Bull, the hospital became an order exempt from the control of the local church. All the Knights were religious, bound by the three monastic vows of poverty, chastity and obedience.
