Passages:
Post-European-contact Chamorro culture is a combination of American, Spanish, Filipino, other Micronesian Islander and Mexican traditions, with few remaining indigenous pre-Hispanic customs. These influences are manifested in the local language, music, dance, sea navigation, cuisine, fishing, games (such as batu, chonka, estuleks, and bayogu), songs and fashion. During Spanish colonial rule (1668–1898) the majority of the population was converted to Roman Catholicism and religious festivities such as Easter and Christmas became widespread. Post-contact Chamorro cuisine is largely based on corn, and includes tortillas, tamales, atole and chilaquiles, which are a clear influence from Spanish trade between Mesoamerica and Asia. The modern Chamorro language is a Malayo-Polynesian language with much Spanish and Filipino influence. Many Chamorros also have Spanish surnames because of their conversion to Roman Catholic Christianity and the adoption of names from the Catálogo alfabético de apellidos, a phenomenon also common to the Philippines. Many Christians still practice their traditional cultural beliefs and rituals along with Christianity. The Catholic Church has fused some aspects of local culture into its services. For example, the singing of hymns during services has developed into a local and traditional way of singing (a repetitive call and response style) in Sesotho, the indigenous language, as well as English. In addition priests are seen dressed in local dress during services. 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. 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.
