Christian mission in the context of "Colonialism"

Medical missions is the term used for Christian missionary endeavors that involve the administration of medical treatment. As has been common among missionary efforts from the 18th to 20th centuries, medical missions often involves residents of the "Western world" traveling to locales within Africa, Asia, Eastern Europe, Latin America, or the Pacific Islands.

In the year before the First Council of Constantinople in 381, Nicene Christianity became the official religion of the Roman Empire when Theodosius I, emperor of the East, Gratian, emperor of the West, and Gratian's junior co-ruler Valentinian II issued the Edict of Thessalonica in 380, which recognized the catholic orthodoxy, as defined by the Council of Nicea, as the Roman Empire's state religion. Historians refer to this state-sponsored church using a variety of terms: the catholic church, the orthodox church, the imperial church, the Roman church, or the Byzantine church, with some also used for wider communions extending beyond the Roman Empire. The Eastern Orthodox Church, Oriental Orthodoxy, and the Catholic Church all claim to stand in continuity from the Nicene Christian church to which Theodosius granted recognition. Political differences between the Eastern Roman Empire and the Persian Sassanid Empire led to the separation of the Church of the East in 424. A doctrinal split within the imperial church led to the independence of early Oriental Orthodoxy, while the fall of the Western Roman Empire initiated the gradual separation between Eastern and Western Christianity, culminating in the East-West schism of 1054. The Western Church evolved into the Latin Catholic Church while the Eastern Church that remained under the patronage of the Eastern empire and evolved into the Greek Orthodox Church.

Earlier in the 4th century, following the Diocletianic Persecution of 303–313 and the Donatist controversy that arose in consequence, Constantine the Great had convened councils of bishops to define the orthodoxy of the Christian faith and to expand on earlier Christian councils. A series of ecumenical councils convened by successive Roman emperors met during the 4th and the 5th centuries, but Christianity continued to suffer rifts and schisms surrounding the theological and christological doctrines of Arianism, Nestorianism, Miaphysitism, and Dyophysitism. In the 5th century, the Western Roman Empire decayed as a polity; invaders sacked Rome in 410 and in 455, and Odoacer, an Arian barbarian warlord, forced Romulus Augustus, the last nominal Western Emperor, to abdicate in 476. However, apart from the aforementioned schisms, the church as an institution persisted in communion, if not without tension, between the East and West. In the 6th century, the Byzantine armies of the Byzantine Emperor Justinian I recovered Italy and other regions of the Western Mediterranean shore. The Byzantine Empire soon lost most of these gains, but it held Rome, as part of the Exarchate of Ravenna, until 751, a period known in church history as the Byzantine Papacy. The early Muslim conquests of the 7th–9th centuries would begin a process of converting most of the then-Christian world in the Levant, Middle East, North Africa, regions of Southern Italy and the Iberian Peninsula to Islam, severely restricting the reach both of the Byzantine Empire and of its church. Christian missionary activity directed from the capital of Constantinople did not lead to a lasting expansion of the formal link between the church and the Byzantine emperor, since areas outside the Byzantine Empire's political and military control set up their own distinct churches, as in the case of Bulgaria in 919.

In Christianity, a disciple is a dedicated follower of Jesus. This term is found in the New Testament only in the Gospels and Acts. Originating in the ancient Near East, the concept of a disciple is an adherent of a teacher. Discipleship is not the same as being a student in the modern sense; a disciple in the ancient biblical world actively imitated both the life and teaching of the master. It was a deliberate apprenticeship which made the fully formed disciple a living copy of the master.

The New Testament records many followers of Jesus during his ministry. Some disciples were given a mission, such as the Little Commission, the commission of the seventy in Luke's Gospel, the Great Commission after the resurrection of Jesus, or the conversion of Paul, making them apostles, charged with proclaiming the gospel (the Good News) to the world. Jesus emphasised that being his disciples would be costly.

Methodism, also called the Methodist movement, is a Protestant Christian tradition whose origins, doctrine and practice derive from the life and teachings of John Wesley. George Whitefield and John's brother Charles Wesley were also significant early leaders in the movement. They were named Methodists for "the methodical way in which they carried out their Christian faith". Methodism originated as a revival movement within Anglicanism with roots in the Church of England in the 18th century and became a separate denomination after Wesley's death. The movement spread throughout the British Empire, the United States and beyond because of vigorous missionary work, and today has about 80 million adherents worldwide. Most Methodist denominations are members of the World Methodist Council.

Wesleyan theology, which is upheld by the Methodist denominations, focuses on sanctification and the transforming effect of faith on the character of a Christian, exemplified by living a victorious life over sin. Unique to Wesleyan Methodism is its definition of sin: a "voluntary transgression of a known law of God." Distinguishing doctrines include the new birth, assurance, imparted righteousness, and obedience to God manifested in performing works of piety. John Wesley held that entire sanctification was "the grand depositum", or foundational doctrine, of the Methodist faith, and its propagation was the reason God brought Methodists into existence. Scripture is considered the primary authority, but Methodists also look to Christian tradition, including the historic creeds. Most Methodists teach that Jesus Christ, the Son of God, died for all of humanity and that salvation is achievable for all. This is the Arminian doctrine, as opposed to the Calvinist position that God has predestined the salvation of a select group of people. However, Whitefield and several other early leaders of the movement were considered Calvinistic Methodists and held to the Calvinist position.

A church (or local church) is a Christian organization or congregation that meets in a particular location, often for worship. Many are formally organized, with constitutions and by-laws, maintain offices, are served by clergy or lay leaders, and, in nations where this is permissible, often seek non-profit corporate status. The term is distinct from the use of the word "church" to mean a church building.

Local churches often relate with, affiliate with, or consider themselves to be constitutive parts of denominations, which are also called churches in many traditions. Depending on the tradition, these organizations may connect local churches to larger church traditions, ordain and defrock clergy, define terms of membership and exercise church discipline, and have organizations for cooperative ministry such as educational institutions and missionary societies. Non-denominational churches are not part of denominations, but may consider themselves part of larger church movements without institutional expression.

A missionary is a member of a religious group who is sent into an area in order to promote its faith or provide services to people, such as education, literacy, social justice, health care, and economic development.

In the Latin translation of the Bible, Jesus Christ says the word when he sends the disciples into areas and commands them to preach the gospel in his name. The term is most commonly used in reference to Christian missions, but it can also be used in reference to any creed or ideology.
