This salvation of souls involved a theology and a sacramental system, which we shall proceed to explain. Theology was the study of God. It sought to explain how and why man was created, what were his actual and desirable relations with God, what would be the fate of man in a future life. The most famous theologians of the Catholic Church, for example, St. Thomas Aquinas (d. 1274), studied carefully the teachings of Christ, the Bible, the early Christian writings, and the decrees of popes and councils, and drew therefrom elaborate explanations of Christian theology—the dogmas and faith of the Catholic Church.
[Sidenote: The Sacramental System]
The very center of Catholic theology was the sacramental system, for that was the means, and essentially the only means, of saving souls. It was, therefore, for the purpose of the sacramental system that the Church and its hierarchy existed. The sacraments were believed to have been instituted by Christ Himself, and were defined as "outward signs instituted by Christ to give grace." The number generally accepted was seven: baptism, confirmation, holy eucharist, penance, extreme unction, holy orders, and matrimony. By means of the sacraments the Church accompanied the faithful throughout life. Baptism, the pouring of water, cleansed the child from original sin and from all previous actual sins, and made him a Christian, a child of God, and an heir of heaven. The priest was the ordinary minister of baptism, but in case of necessity any one who had the use of reason might baptize. Confirmation, conferred usually by a bishop upon young persons by the laying on of hands and the anointing with oil, gave them the Holy Ghost to render them strong and perfect Christians and soldiers of Jesus Christ. Penance, one of the most important sacraments, was intended to forgive sins committed after baptism. To receive the sacrament of penance worthily it was necessary for the penitent (1) to examine his conscience, (2) to have sorrow for his sins, (3) to make a firm resolution never more to offend God, (4) to confess his mortal sins orally to a priest, (5) to receive absolution from the priest, (6) to accept the particular penance—visitation of churches, saying of certain prayers, or almsgiving—which the priest might enjoin. The holy eucharist was the sacrament of the Lord's Supper, the consecration of bread and wine by priest or bishop, its miraculous transformation (transubstantiation) at his word into the very Body and Blood of Christ, and its reception by the faithful. It was around the eucharist that the elaborate ritual and ceremonies of the Mass developed, that fine vestments and candles and incense and flowers were used, and that magnificent cathedrals were erected. Extreme unction was the anointing at the hands of a priest of the Christian who was in immediate danger of death, and it was supposed to give health and strength to the soul and sometimes to the body. By means of holy orders,—the special imposition of hands on the part of a bishop,—priests, bishops, and other ministers of the Church were ordained and received the power and grace to perform their sacred duties. Matrimony was the sacrament, held to be indissoluble by human power, by which man and woman were united in lawful Christian marriage.
Of the seven sacraments it will be noticed that two—baptism and penance—dealt with the forgiveness of sins, and that two—holy orders and matrimony—were received only by certain persons. Three—baptism, confirmation, and holy orders—could be received by a Christian only once. Two—confirmation and holy orders—required the ministry of a bishop; and all others, except baptism and possibly matrimony, required the ministry of at least a priest. The priesthood was, therefore, the absolutely indispensable agent of the Church in the administration of the sacramental system. It was the priesthood that absolved penitents from their sins, wrought the great daily miracle of transubstantiation, and offered to God the holy sacrifice of the Mass.
[Sidenote: Various Objections to the Church]
It must not be supposed that either the theology or the organization of the Catholic Church, as they existed in the year 1500, had been precisely the same throughout the Christian era. While educated Catholics insisted that Christ was indirectly the source of all faith and all practice, they were quite willing to admit that external changes and adaptations of institutions to varying conditions had taken place. Moreover, it must not be supposed that the proud eminence to which the Catholic Church had attained by 1500 in central and western Europe had been won easily or at that time was readily maintained. Throughout the whole course of Christian history there had been repeated objections to new definitions of dogma—many positively refused to accept the teaching of the Church as divine or infallible— and there had been likewise a good deal of opposition to the temporal claims of the Church, resulting in increasing friction between the clergy and the lay rulers. Thus it often transpired that the kings who vied with one another in recognizing the spiritual and religious headship of the pope and in burning heretics who denied doctrines of the Catholic Church, were the very kings who quarreled with the pope concerning the latter's civil jurisdiction and directed harsh laws against its exercise.
[Sidenote: Sources of Conflict between Church and State]
As strong national monarchies rose in western Europe, this friction became more acute. On one side the royal power was determined to exalt the state and to bring into subjection to it not only the nobles and common people but the clergy as well; the national state must manage absolutely every temporal affair. On the other side, the clergy stoutly defended the special powers that they had long enjoyed in various states and which they believed to be rightly theirs. There were four chief sources of conflict between the temporal and spiritual jurisdictions, (1) Appointments of bishops, abbots, and other high church officers. Inasmuch as these were usually foremost citizens of their native kingdom, holding large estates and actually participating in the conduct of government, the kings frequently claimed the right to dictate their election. On the other hand the popes insisted upon their rights in the matter and often "reserved" to themselves the appointment to certain valuable bishoprics. (2) Taxation of land and other property of the clergy. The clergy insisted that by right they were exempt from taxation and that in practice they had not been taxed since the first public recognition of Christianity in the fourth century. The kings pointed out that the wealth of the clergy and the needs of the state had increased along parallel lines, that the clergy were citizens of the state and should pay a just share for its maintenance. (3) Ecclesiastical courts. For several centuries the Church had maintained its own courts for trying clerical offenders and for hearing certain cases, which nowadays are heard in state courts— probating of wills, the marriage relations, blasphemy, etc. From these local church courts, the pope insisted that appeals might be taken to the Roman Curia. On their side, the kings were resolved to substitute royal justice for that of both feudal and ecclesiastical courts: they diminished, therefore, the privileges of the local church courts and forbade the taking of appeals to Rome. (4) How far might the pope, as universally acknowledged head of the Church, interfere in the internal affairs of particular states? While the pope claimed to be the sole judge of his own rights and powers, several kings forbade the publication of papal documents within their states or the reception of papal legates unless the royal assent had been vouchsafed.
[Sidenote: Royal Restrictions on the Church]
Gradually the national monarchs secured at least a partial control over episcopal appointments, and in both England and France papal jurisdiction was seriously restricted in other ways. In England the power of the ecclesiastical courts had been reduced (1164); no property might be bestowed upon the Church without royal permission (1279); the pope might not make provision in England for his personal appointees to office (1351); and appeals to Rome had been forbidden (1392). [Footnote: All these anti-papal enactments were very poorly enforced.] In France the clergy had been taxed early in the fourteenth century, and the papacy, which had condemned such action, had been humiliated by a forced temporary removal from Rome to Avignon, where it was controlled by French rulers for nearly seventy years (1309-1377); and in 1438 the French king, Charles VII, in a document, styled the Pragmatic Sanction of Bourges, solemnly proclaimed the "liberties of the Gallican Church," that a general council was superior to the pope, that the pope might not interfere in episcopal elections, that he might not levy taxes on French dioceses. The Pragmatic Sanction was condemned by the pope, but for three-quarters of a century after its issuance there were strained relations between the Church in France and the sovereign pontiff.
