The Church in the Late Middle Ages
The Renaissance began in times of religious turmoil. The late Middle Ages was a period of political intrigue surrounding the Papacy, culminating in the Western Schism, in which three men simultaneously claimed to be true Bishop of Rome. While the schism was resolved by the Council of Constance (1414), a resulting reform movement known as Conciliarism sought to limit the power of the pope. Although the papacy eventually emerged supreme in ecclesiastical matters by the Fifth Council of the Lateran (1511), it was dogged by continued accusations of corruption, most famously in the person of Pope Alexander VI, who was accused variously of simony, nepotism and fathering four children.

Churchmen such as Erasmus and Luther proposed reform to the Church, often based on humanist textual criticism of the New Testament. In October 1517 Luther published the 95 Theses, challenging papal authority and criticizing its perceived corruption, particularly with regard to instances of sold indulgences. The 95 Theses led to the Reformation, a break with the Roman Catholic Church that previously claimed hegemony in Western Europe. Humanism and the Renaissance therefore played a direct role in sparking the Reformation, as well as in many other contemporaneous religious debates and conflicts.
Pope Paul III came to the papal throne (1534–1549) after the sack of Rome in 1527, with uncertainties prevalent in the Catholic Church following the Protestant Reformation. Nicolaus Copernicus dedicated De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres) to Paul III, who became the grandfather of Alessandro Farnese (cardinal), who had paintings by Titian, Michelangelo, and Raphael, as well as an important collection of drawings, and who commissioned the masterpiece of Giulio Clovio, arguably the last major illuminated manuscript, the Farnese Hours.
The Church and the Renaissance
The City of Rome, the Papacy, and the Papal States were all affected by the Renaissance. On the one hand, it was a time of great artistic patronage and architectural magnificence, where the Church pardoned and even sponsored such artists as Michelangelo, Brunelleschi, Bramante, Raphael, Fra Angelico, Donatello, and da Vinci. On the other hand, wealthy Italian families often secured episcopal offices, including the papacy, for their own members, some of whom were known for immorality.
In the revival of neo-Platonism and other ancient philosophies, Renaissance humanists did not reject Christianity; quite the contrary, many of the Renaissance's greatest works were devoted to it, and the Church patronized many works of Renaissance art. The new ideals of humanism, although more secular in some aspects, developed against a Christian backdrop, especially in the Northern Renaissance. In turn, the Renaissance had a profound effect on contemporary theology, particularly in the way people perceived the relationship between man and God.

Michelangelo's Pietà exemplifies the character of Renaissance art, combining the classical aesthetic of Greek art with religious imagery, in this case Mother Mary holding the body of Jesus after the crucifixion.
In addition to being the head of the Church, the Pope became one of Italy's most important secular rulers, and pontiffs such as Julius II often waged campaigns to protect and expand their temporal domains. Furthermore, the popes, in a spirit of refined competition with other Italian lords, spent lavishly both on private luxuries but also on public works, repairing or building churches, bridges, and a magnificent system of aqueducts in Rome that still function today.
From 1505 to 1626, St. Peter's Basilica, perhaps the most recognised Christian church, was built on the site of the old Constantinian basilica in Rome. It was also a time of increased contact with Greek culture, opening up new avenues of learning, especially in the fields of philosophy, poetry, classics, rhetoric, and political science, fostering a spirit of humanism–all of which would influence the Church.
Counter-Reformation
The Counter-Reformation, also called the Catholic Reformation or the Catholic Revival, was the period of Catholic resurgence initiated in response to the Protestant Reformation, beginning with the Council of Trent (1545–1563) and ending at the close of the Thirty Years' War (1648). The Counter-Reformation was a comprehensive effort composed of four major elements, ecclesiastical or structural reconfigurations, new religious orders (such as the Jesuits), spiritual movements, and political reform.
Such reforms included the foundation of seminaries for the proper training of priests in the spiritual life and the theological traditions of the Church, the reform of religious life by returning orders to their spiritual foundations, and new spiritual movements focusing on the devotional life and a personal relationship with Christ, including the Spanish mystics and the French school of spirituality. It also involved political activities that included the Roman Inquisition. One primary emphasis of the Counter-Reformation was a mission to reach parts of the world that had been colonized as predominantly Catholic and also try to reconvert areas such as Sweden and England that were at one time Catholic, but had been Protestantized during the Reformation.
