Geoffrey Blainey likened the Catholic Church in its activities during the Middle Ages to an early version of a welfare state: "It conducted hospitals for the old and orphanages for the young; hospices for the sick of all ages; places for the lepers; and hostels or inns where pilgrims could buy a cheap bed and meal". It supplied food to the population during famine and distributed food to the poor. This welfare system the church funded through collecting taxes on a large scale and possessing large farmlands and estates. It was common for monks and clerics to practice medicine and medical students in northern European universities often took minor Holy orders. Mediaeval hospitals had a strongly Christian ethos and were, in the words of historian of medicine Roy Porter, "religious foundations through and through"; Ecclesiastical regulations were passed to govern medicine, partly to prevent clergymen profiting from medicine.
