Philip Melanchthon in the context of "Protestant reformer"

All Saints' Church, commonly referred to as Schlosskirche (Castle Church) to distinguish it from the Stadtkirche (Town Church) of St. Mary's, sometimes known as the Reformation Memorial Church, is a Lutheran church in Wittenberg, Saxony-Anhalt, Germany. It is the site where, according to Philip Melanchthon, the Ninety-five Theses were posted by Martin Luther in 1517, launching the beginning of the Protestant Reformation.

Beginning in 1883, the church was restored as a memorial site and re-inaugurated on 31 October 1892, 375 years after Luther's posting. Because of its religious significance and testimony to the lasting global effects of the Reformation, the church was inscribed on the UNESCO World Heritage List in 1996 along with other sites in Wittenberg and Eisleben associated with Martin Luther and Philip Melanchthon.

Protestant Reformers were theologians whose careers, works and actions brought about the Protestant Reformation of the 16th century.

In the context of the Reformation, Martin Luther was the first reformer, sharing his views publicly in 1517, followed by Andreas Karlstadt and Philip Melanchthon at Wittenberg, who promptly joined the new movement. In 1519, Huldrych Zwingli became the first reformer to express a form of the Reformed tradition.

The Luther Bible (German: Lutherbibel) is a German language Bible translation by the Protestant reformer Martin Luther. A New Testament translation by Luther was first published in September 1522; the completed Bible contained 75 books, including the Old Testament, Apocrypha and New Testament, which was printed in 1534. Luther continued to make improvements to the text until 1545. It was one of the first full translations of the Bible into German that used not only the Latin Vulgate but the original Hebrew and Greek.

Luther did not translate the entire Bible by himself; he relied on a team of translators and helpers that included Philip Melanchthon, a scholar of Koine Greek who motivated and assisted Luther's New Testament translation from Greek, and Matthäus Aurogallus, a linguist and scholar of Hebrew. One of the textual bases of the New Testament translation was the bilingual Latin and Greek version, with its philological annotations, recently published by the Dutch Catholic humanist Erasmus of Rotterdam and called the Novum Testamentum omne (1519).

Mennonites are a group of Anabaptist Christian communities tracing their roots to the epoch of the Radical Reformation. The name Mennonites is derived from the cleric Menno Simons (1496–1561) of Friesland, part of the Habsburg Netherlands within the Holy Roman Empire, present day Netherlands. Menno Simons became a prominent leader within the wider Anabaptist movement and was a contemporary of Martin Luther (1483–1546) and Philip Melanchthon (1497–1560). Through his writings about the Reformation Simons articulated and formalized the teachings of earlier Swiss Anabaptist founders as well as early teachings of the Mennonites founded on the belief in both the mission and ministry of Jesus. Formal Mennonite beliefs were codified in the Dordrecht Confession of Faith (1632), which affirmed "the baptism of believers only, the washing of the feet as a symbol of servanthood, church discipline, the shunning of the excommunicated, the non-swearing of oaths, marriage within the same church", nonresistance, and in general, more emphasis on "true Christianity" involving "being Christian and obeying Christ" as they interpret it from the Holy Bible.

The majority of the early Mennonite followers, rather than fighting, survived by fleeing to neighboring states where ruling families were tolerant of their belief in believer's baptism. Over the years, Mennonites have become known as one of the historic peace churches, due to their commitment to pacifism. Mennonites seek to emphasize the teachings of early Christianity in their beliefs, worship and lifestyle.
