Question: Who married the man who wanted to reform the institution behind the denomination constituting 12.6% of Christians in New Zealand?

Knowledge 1: New Zealand
Christianity is the predominant religion in New Zealand, although its society is among the most secular in the world. In the 2013 census, 55.0% of the population identified with one or more religions, including 49.0% identifying as Christians. Another 41.9% indicated that they had no religion. The main Christian denominations are, by number of adherents, Roman Catholicism (12.6%), Anglicanism (11.8%), Presbyterianism (8.5%) and "Christian not further defined" (i.e. people identifying as Christian but not stating the denomination, 5.5%). The Māori-based Ringatū and Rātana religions (1.4%) are also Christian in origin. Immigration and demographic change in recent decades has contributed to the growth of minority religions, such as Hinduism (2.1%), Buddhism (1.5%), Islam (1.2%) and Sikhism (0.5%). The Auckland Region exhibited the greatest religious diversity. [SEP] Knowledge 2: Reformation
Although there had been significant earlier attempts to reform the Catholic Church before Luther -- such as those of Jan Hus, Peter Waldo, and John Wycliffe -- Martin Luther is widely acknowledged to have started the Reformation with the Ninety - five Theses. Luther began by criticising the sale of indulgences, insisting that the Pope had no authority over purgatory and that the Catholic doctrine of the merits of the saints had no foundation in the Bible. The Protestant Reformation, however, would come to incorporate doctrinal changes such as a complete reliance on Scripture as a source of proper belief (sola scriptura) and the belief that faith in Jesus, and not good works, is the only way to obtain God's pardon for sin (sola fide). The core motivation behind these changes was theological, though many other factors played a part, including the rise of nationalism, the Western Schism that eroded loyalty to the Papacy, the perceived corruption of the Roman Curia, the impact of humanism, and the new learning of the Renaissance that questioned much traditional thought. [SEP] Knowledge 3: Katharina von Bora
Katharina von Bora (; 29 January 1499 – 20 December 1552), after her wedding Katharina Luther, also referred to as "die Lutherin" ("the Lutheress"), was the wife of Martin Luther, German reformer and a seminal figure of the Protestant Reformation. Beyond what is found in the writings of Luther and some of his contemporaries, little is known about her. Despite this, Katharina is often considered one of the most important participants in the Reformation because of her role in helping to define Protestant family life and setting the tone for clergy marriages. [SEP] Knowledge 4: Presbyterianism
The roots of Presbyterianism lie in the European Reformation of the 16th century; the example of John Calvin's Geneva being particularly influential. Most Reformed churches which trace their history back to Scotland are either presbyterian or congregationalist in government. In the twentieth century, some Presbyterians played an important role in the ecumenical movement, including the World Council of Churches. Many Presbyterian denominations have found ways of working together with other Reformed denominations and Christians of other traditions, especially in the World Communion of Reformed Churches. Some Presbyterian churches have entered into unions with other churches, such as Congregationalists, Lutherans, Anglicans, and Methodists. Presbyterians in the United States came largely from Scotch-Irish immigrants communities, and also from New England Yankee communities that had originally been Congregational but changed because of an agreed-upon "Plan of Union of 1801" for frontier areas.

[SEP] Knowledge 4: Presbyterianism
Presbyterian history is part of the history of Christianity, but the beginning of Presbyterianism as a distinct movement occurred during the 16th - century Protestant Reformation. As the Catholic Church resisted the reformers, several different theological movements splintered from the Church and bore different denominations. Presbyterianism was especially influenced by the French theologian John Calvin, who is credited with the development of Reformed theology, and the work of John Knox, a Scotsman and a Roman Catholic Priest, who studied with Calvin in Geneva, Switzerland. He brought back Reformed teachings to Scotland. The Presbyterian church traces its ancestry back primarily to England and Scotland. In August 1560 the Parliament of Scotland adopted the Scots Confession as the creed of the Scottish Kingdom. In December 1560, the First Book of Discipline was published, outlining important doctrinal issues but also establishing regulations for church government, including the creation of ten ecclesiastical districts with appointed superintendents which later became known as presbyteries.

[SEP] Knowledge 4: Presbyterianism
Presbyterianism is a part of the Reformed tradition within Protestantism which traces its origins to the British Isles. Presbyterian churches derive their name from the presbyterian form of church government, which is governed by representative assemblies of elders. Many Reformed churches are organized this way, but the word "Presbyterian," when capitalized, is often applied uniquely to the churches that trace their roots to the Scottish and English churches that bore that name and English political groups that formed during the English Civil War. Presbyterian theology typically emphasizes the sovereignty of God, the authority of the Scriptures, and the necessity of grace through faith in Christ. Presbyterian church government was ensured in Scotland by the Acts of Union in 1707 which created the kingdom of Great Britain. In fact, most Presbyterians found in England can trace a Scottish connection, and the Presbyterian denomination was also taken to North America mostly by Scots and Scots-Irish immigrants. The Presbyterian denominations in Scotland hold to the theology of John Calvin and his immediate successors, although there are a range of theological views within contemporary Presbyterianism. Local congregations of churches which use presbyterian polity are governed by sessions made up of representatives of the congregation (elders); a conciliar approach which is found at other levels of decision-making (presbytery, synod and general assembly).
