Protestantism originated from work of several theologians starting in the 12th century, although there could have been earlier cases of which there is no surviving evidence.
 Their opinions were subject to persecution by the Roman Catholic Church, and thus were kept isolated or effectively eradicated up to the 16th century.
 One of the early Protestant reformers was John Wycliffe, a theologian and an early proponent of reform in the 14th century.
 He influenced Jan Hus, a Czech priest from Prague, whose followers soon dominated the Kingdom of Bohemia.
 Hus in turn influenced German monk Martin Luther, who spread the Protestant Reformation.
 Originally, both Hus and Luther intended to reform the Roman Catholic Church rather than break it up.

Mysterium Paschale.
 The Mystery of Easter (German: "Theologie der Drei Tage" ) is a 1970 book by the Swiss theologian and Catholic priest Hans Urs von Balthasar.
 It offers an account of the death and resurrection of Christ, and their significance for the Christian life.
 Balthasar discusses the "bodiliness" of the Resurrection from the "radical" death of Jesus, involving his descent into the place of the dead on Holy Saturday.
 Balthasar's willingness to assume the nature and the consequence of his sin makes him, as well as the reader, extrapolate that God can endure and conquer godlessness, abandonment, and death.
 In the "Preface to the Second Edition", Balthasar takes a cue from Revelation (Vulgate: "agni qui occisus est ab origine mundi", NIV: "the Lamb who was slain from the creation of the world") to explore the idea that, from the "immanent Trinity" up to the "economic" One, "God is love" consists in an "eternal super-kenosis".

Preston is a city in Lancashire, England, that contains about 340 listed buildings.
 Its recorded history goes back to the Roman era, and in the medieval period it was a market town and a port, its first charter being granted in 1179.
 The city stands at the lowest crossing point of the River Ribble, which has given it great strategic importance.
 From the 16th century it was a centre for the spinning and weaving industries, and its greatest growth came from the 1770s with the development of steam power.
 By 1835 (when it was still a town) it contained 40 factories, and this had grown to 77 factories in 1869.
 Its population rose from about 12,000 in 1801 to about 69,000 in 1851, and one reflection of this was and this resulted in poor housing and social conditions.

Elizabeth A. Johnson (born December 6, 1941) is a Roman Catholic feminist theologian.
 She is a Distinguished Professor of Theology at Fordham University, a Jesuit institution in New York City.
 She is a member of the Sisters of St. Joseph of Brentwood.
 Johnson has served as president of the Catholic Theological Society of America and is "one of its most well known members."
 "The New York Times" has described Johnson as "a highly respected theologian whose books are widely used in theology classes."
 Johnson's controversial "Quest for the Living God" was hailed for expounding on "new ways to think and speak about God within the framework of traditional Catholic beliefs and motifs."
 It became popular in churches and was adopted as a text for many university religion courses, but in 2011 the United States Conference of Catholic Bishops' (USCCB) Committee on Doctrine issued a doctrinal evaluation of the book that concluded it did not correspond with "authentic Catholic teaching."
 The public criticism by the bishops created "a substantial boon in sales of Quest," and frayed already strained relations between the church hierarchy and Catholic theologians. "
The New York Times" notes that Johnson has been criticized by some Catholic groups, such as the Cardinal Newman Society, because of her support for giving women greater authority in the church and her willingness to speak at meetings of Catholics who disagree with the church on such issues as the church's condemnation of same-sex marriage.
