Evangelism in the context of "Conversion to Christianity"

An itinerant preacher (also known as an itinerant minister) is a Christian evangelist who preaches the basic Christian redemption message while traveling around to different groups of people within a relatively short period of time. The usage of these travelling evangelists is known as itineracy or itinerancy.

Mendicant orders are primarily certain Catholic religious orders that have vowed for their male members a lifestyle of poverty, traveling, and living in urban areas for purposes of preaching, evangelization, and ministry, especially to less wealthy individuals. At their foundation these orders rejected the previously established monastic model, which prescribed living in one stable, isolated community where members worked at a trade and owned property in common, including land, buildings and other wealth. By contrast, the mendicants avoided owning property, did not work at a trade, and embraced a poor, often itinerant lifestyle. They depended for their survival on the goodwill of the people to whom they preached. The members of these orders are not called monks but friars.

The term "mendicant" is also used with reference to some non-Christian religions to denote holy persons committed to an ascetic lifestyle, which may include members of religious orders and individual holy persons.

The Christian mission can be understood as the conviction that all believers are called to spread the Christian gospel to the whole world, in accordance, for example, with the Great Commission set out by Jesus Christ and recorded in Matthew 28:16-20. More specifically, a Christian Mission is an organized effort to carry on evangelism, in the name of the Christian faith, or a location established for this purpose. Missions involve sending individuals and groups across boundaries, most commonly geographical boundaries. Sometimes individuals are sent and are called missionaries, and historically may have been based in mission stations. When groups are sent, they are often called mission teams and they undertake mission trips. There are a few different kinds of mission trips: short-term, long-term, relational and those that simply help people in need. Some people choose to dedicate their whole lives to mission.

Missionaries preach the Christian faith and sometimes administer the sacraments, and provide humanitarian aid or services. Christian doctrines (such as the "Doctrine of Love" professed by many missions) permit the provision of aid without requiring religious conversion. Nonetheless, the provision of help has always been closely tied to evangelization efforts.

Christian theology is the theology – the systematic study of the divine and religion – of Christian belief and practice. It concentrates primarily upon the texts of the Old Testament and of the New Testament, as well as on Christian tradition. Christian theologians use biblical exegesis, rational analysis and argument. Theologians may undertake the study of Christian theology for a variety of reasons, such as in order to:

• help them better understand Christian tenets
• make comparisons between Christianity and other traditions
• defend Christianity against objections and criticism
• facilitate reforms in the Christian church
• assist in the propagation of Christianity
• draw on the resources of the Christian tradition to address some present situation or perceived need
• education in Christian philosophy, especially in Neoplatonic philosophy

Evangelicalism (/ˌiːvænˈdʒɛlɪkəlɪzəm, ˌɛvæn-, -ən-/), also called evangelical Christianity or evangelical Protestantism, is a worldwide, interdenominational movement within Protestant Christianity that emphasizes evangelism, or the preaching and spreading of the Christian gospel. The term evangelical is derived from the Koine Greek word euangelion, meaning "good news," in reference to the message of salvation through Jesus Christ. Evangelicalism typically places a strong emphasis on personal conversion, often described as being "born again", and regards the Bible as the ultimate authority in matters of faith and practice. The definition and scope of evangelicalism are subjects of debate among theologians and scholars. Some critics argue that the term encompasses a wide and diverse range of beliefs and practices, making it difficult to define as a coherent or unified movement.

The theological roots of evangelicalism can be traced to the Protestant Reformation in 16th-century Europe, particularly Martin Luther's 1517 Ninety-five Theses, which emphasized the authority of Scripture and the preaching of the gospel over church tradition. The modern evangelical movement is generally dated to around 1738, influenced by theological currents such as Pietism, Puritanism, Quakerism, and Moravianism—notably the work of Nicolaus Zinzendorf and the Herrnhut community. Evangelicalism gained momentum during the First Great Awakening, with figures like John Wesley and the early Methodists playing central roles.

Jehovah's Witnesses is a nontrinitarian, millenarian, and restorationist Christian denomination, stemming from the Bible Student movement founded by Charles Taze Russell in the nineteenth century. Russell co-founded Zion's Watch Tower Tract Society in 1881 to organize and print the movement's publications. A leadership dispute after Russell's death resulted in several groups breaking away, with Joseph Franklin Rutherford retaining control of the Watch Tower Society and its properties. Rutherford made significant organizational and doctrinal changes, including adoption of the name Jehovah's witnesses in 1931 to distinguish the group from other Bible Student groups and symbolize a break with the legacy of Russell's traditions. In 2024, Jehovah's Witnesses reported a peak membership of approximately 9 million worldwide.

Jehovah's Witnesses are known for their evangelism, distributing literature such as The Watchtower and Awake!, and for refusing military service and blood transfusions. They consider the use of God's name vital for proper worship. They reject Trinitarianism, inherent immortality of the soul, and hellfire, which they consider unscriptural doctrines. Jehovah's Witnesses believe that the destruction of the present world system at Armageddon is imminent, and the establishment of God's kingdom over earth is the only solution to all of humanity's problems. They do not observe Christmas, Easter, birthdays, or other holidays and customs they consider to have pagan origins incompatible with Christianity. They prefer to use their own Bible translation, the New World Translation of the Holy Scriptures.

The Amish (/ˈɑːmɪʃ/ , also /ˈæmɪʃ/ or /ˈeɪmɪʃ/; Pennsylvania German: Amisch), formally the Old Order Amish, are a group of traditionalist Anabaptist Christian church fellowships with Swiss and Alsatian origins. As they maintain a degree of separation from surrounding populations, and hold their faith in common, the Amish have been described by certain scholars as an ethnoreligious group, combining features of an ethnicity and a Christian denomination. The Amish are closely related to Old Order Mennonites and Conservative Mennonites, denominations that are also a part of Anabaptist Christianity. The Amish are known for simple living, plain dress, Christian pacifism, and slowness to adopt many conveniences of modern technology, with a view neither to interrupt family time, nor replace face-to-face conversations whenever possible, and a view to maintain self-sufficiency. The Amish value rural life, manual labor, humility and Gelassenheit (submission to God's will).

The Amish church began with a schism in Switzerland within a group of Swiss and Alsatian Mennonite Anabaptists in 1693 led by Jakob Ammann. Those who followed Ammann became known as Amish. In the second half of the 19th century, the Amish divided into Old Order Amish and Amish Mennonites; the latter do not abstain from using motor cars, whereas the Old Order Amish retained much of their traditional culture. When people refer to the Amish today, they normally refer to the Old Order Amish, though there are other subgroups of Amish. The Amish fall into three main subgroups—the Old Order Amish, the New Order Amish, and the Beachy Amish—all of whom wear plain dress and live their life according to the Bible as codified in their church's Ordnung. The Old Order Amish and New Order Amish conduct their worship in German, speak Pennsylvania Dutch, and use buggies for transportation, in contrast to the Beachy Amish who use modern technology (inclusive of motor cars) and conduct worship in the local language of the area in which they reside. Both the New Order Amish and the Beachy Amish emphasize the New Birth, evangelize to seek converts, and have Sunday schools.

Proselytism (/ˈprɒsəlɪtɪzəm/ ) is the policy of attempting to convert people's religious beliefs. Carrying out attempts to instill beliefs can be called proselytization.

Proselytism is illegal in some countries. Some draw distinctions between Christian evangelism and proselytism, regarding proselytism as involuntary or coerced; the two terms can also be understood to merely be synonyms.
