Luther's attack by the elite clergy for his study of Hebrew and Jewish texts, brought him fully in line with the humanist educational reforms who favored academic freedom, Luther borrowed from Humanism the sense of individualism, that each man can be his own priest. Led by Erasmus, the humanists condemned various forms of corruption within the church, Erasmus held that true religion was a matter of inward devotion rather than outward symbols of ceremony and ritual. Favoring moral reforms and de-emphasizing didactic ritual, Erasmus laid the groundwork for Luther. Humanism's intellectual anti-clericalism would profoundly influence Luther. Some philosophers of the Enlightenment, including Voltaire, attacked the Catholic Church, its leadership and priests claiming moral corruption of many of its clergy and pope's control over political matters and also taxes ,In the North, burghers and monarchs were united in their frustration for not paying any taxes to the nation, but collecting taxes from subjects and sending the revenues disproportionately to the Pope in Italy especially considering the recent strings of political humiliation, such as the apprehension of Pope Boniface VIII by Philip IV of France.
Luther appealed to the growing national consciousness of the German states because he denounced the Pope for involvement in politics as well as religion. The disputation protests against clerical abuses, especially the sale of indulgences.this cause provoked Martin Luther to write his Ninety-Five Theses, condemning what he saw as the purchase and sale of salvation. In Thesis 86, which asks: "Why does the pope, whose wealth today is greater than the wealth of the richest Crassus, build the basilica of Saint Peter with the money of poor believers rather than with his own money?"He insisted that, since forgiveness was God's alone to grant, those who claimed that indulgences absolved buyers from all punishments and granted them salvation were in error. Christians, he said, must not slacken in following Christ on account of such false assurances.The Ninety-Five Theses not only denounced such transactions as worldly but denied the Pope's right to grant pardons on God's behalf in the first place: the only thing indulgences guaranteed, Luther said, was an increase in profit and greed, because the pardon of the Church was in God's power alone.
Moreover, he backed the nobility, which was now justified to crush the Great Peasant Revolt of 1525 and to confiscate church property by Luther's Doctrine of the Two Kingdoms,Luther's book, On Secular Authority, was an ardent expression of the principle of Liberty of Conscience. "Liberty of conscience" is the principle that forbids human authorities from coercing people's spiritual beliefs. In this book, Luther insisted that God requires voluntary religious beliefs. Compelled or coerced faith is insincere and must never be allowed. Luther insisted that "liberty of conscience" was one of Jesus Christ's principles. According to Luther, the civil government's role is simply to keep outward peace in society. The civil government has no business enforcing spiritual laws. "The laws of worldly government extend no farther than to life and property and what is external upon earth", Luther's articulation of the parameters of civil government was a monumental step in the development of the separation of church and state. He argued for a clear distinction between two separate spheres: civil and spiritual. This is known as the Doctrine of the two kingdoms.
Protestantism is one of the major divisions within Christianity. It has been defined as
1) (Solo Christo) denying the universal authority of the Pope, the teaching that Christ is the only mediator between God and man, and that there is salvation through no other, This principle rejects "sacerdotalism," which is the belief that there are no sacraments in the church without the services of priests ordained by apostolic succession under the authority of the pope.
2) (Sola fide) affirming the Reformation principles of justification by faith alone without any mixture of or need for good works, it is summarized with the formula "Faith yields justification and good works" and as contrasted with the Roman Catholic formula "Faith and good works yield justification."
3) the priesthood of all believers
4) (Sola scriptura) the primacy of the Bible as the only source of revealed truth, it is perspicuous and self-interpreting.
Evangelicalism is a Protestant Christian movement that began in the 17th century, Calvinists broke with the Roman Catholic church but differed with Lutherans on the real presence of Christ in the Lord's supper, theories of worship, and the use of God's law for believers.
Augustine Influence on Protestant reformers in Free Will
Augustine taught that Adam's guilt as transmitted to his descendants much enfeebles, Total depravity is a theological doctrine derived from the Augustinian concept of original sin. It is the teaching that, as a consequence of the Fall of Man, every person born into the world is enslaved to the service of sin and, apart from the efficacious or prevenient grace of God, is utterly unable to choose to follow God, refrain from evil, or accept the gift of salvation as it is offered., He also argues that those who are saved have been predetermined to be saved by God prior to birth.
Protestant reformers Martin Luther and John Calvin affirmed that Original Sin completely destroyed liberty
The Catholic Church maintains humans retained a free but wounded will after the Fall. Accordingly, the Catholic Church condemned as heresy any doctrine asserting "since Adam's sin, the free will of man is lost and extinguished"
Pope's Supremacy Over Faith
Another disagreement between Catholicism and Protestantism is over the office and authority of the Pope. According to Catholicism the Pope is the “Vicar of Christ” , and takes the place of Jesus as the visible head of the Church. As such, he has the ability to speak ex cathedra (with authority on matters of faith and practice), and when he does so his teachings are considered infallible and binding upon all Christians. On the other hand, Protestants believe that no human being is infallible, and that Christ alone is the Head of the Church. Catholics rely on apostolic succession as a way of trying to establish the Pope’s authority. But Protestants believe that the church’s authority does not come from apostolic succession, but instead is derived from the Word of God. Spiritual power and authority does not rest in the hands of a mere man, but in the very Word of God. While Catholicism teaches that only the Catholic Church can properly and correctly interpret the Bible, Protestants believe that the Bible teaches that God sent the Holy Spirit to indwell all born-again believers, enabling all believers to understand the message of the Bible.
Church's Rule over Civil States
When the Western Roman Empire began to disintegrate, Augustine developed the concept of the Catholic Church as a spiritual City of God (in a book of the same name), distinct from the material Earthly City. His thoughts profoundly influenced the medieval worldview. Augustine's City of God was closely identified with the Church, the community that worshiped the Trinity. Augustine distinguished two kingdoms of men and God, the temporal and spiritual power. The temporal power, because it is based on natural law, which part of inequality physical men, is imperfect. The temporal power must submit to the spiritual power, and just perfect. The State, with Augustine, must be the guarantor of divine order, serve the interests of the Church
The Catholic Church has a similar doctrine called the doctrine of the two swords, in the bull Unam Sanctam, issued by Pope Boniface VIII. In this bull, Boniface teaches that there is only one Kingdom, the Church, and that the Church controls the spiritual sword, while the temporal sword is controlled by the State, although the temporal sword is hierarchically lower than the spiritual sword, allowing for Church influence in politics and society at large.The Bull lays down dogmatic propositions on the unity of the Catholic Church, the necessity of belonging to it for eternal salvation, the position of the pope as supreme head of the Church, and the duty thence arising of submission to the pope in order to belong to the Church and thus to attain salvation. The pope further emphasizes the higher position of the spiritual in comparison with the secular order.
Government may be, and should be, rule by the ideal Christian ruler, whom the Protestants later called “the godly prince”; such a ruler would lead his people in obedience to God.
