The ecclesiastical supremacy was gradually interpreted to mean that the Bishop of Rome was the _one_ or universal bishop in whom all spiritual and ecclesiastical powers were summed up, and that all other members of the hierarchy were simply delegates selected by him for the purposes of administration. On this interpretation, the Bishop of Rome was the absolute monarch over a kingdom which was called spiritual, but which was as thoroughly material as were those of France, Spain, or England. For, according to mediæval ideas, men were spiritual if they had taken orders, or were under monastic vows; fields, drains, and fences were spiritual things if they were Church property; a house, a barn, or a byre was a spiritual thing, if it stood on land belonging to the Church. This papal kingdom, miscalled spiritual, lay scattered over Europe in diocesan lands, convent estates, and parish glebes—interwoven in the web of the ordinary kingdoms and principalities of Europe. It was part of the Pope’s claim to _spiritual_ supremacy that his subjects (the clergy) owed no allegiance to the monarch within whose territories they resided; that they lived outside the sphere of civil legislation and taxation; and that they were under special laws imposed on them by their supreme spiritual ruler, and paid taxes to him and to him alone. The claim to spiritual supremacy therefore involved endless interference with the rights of temporal sovereignty in every country in Europe, and things civil and things sacred were so inextricably mixed that it is quite impossible to speak of the Reformation as a purely religious movement. It was also an endeavour to put an end to the exemption of the Church and its possessions from all secular control, and to her constant encroachment on secular territory. To show how this claim for spiritual supremacy trespassed continually on the domain of secular authority and created a spirit of unrest all over Europe, we have only to look at its exercise in the matter of patronage to benefices, to the way in which the common law of the Church interfered with the special civil laws of European States, and to the increasing burden of papal requisitions of money.
