Protestant Reformation
The Reformation, also known as the Protestant Reformation or the European Reformation, was a time of major theological movement in Western Christianity in 16th-century Europe that posed a religious and political challenge to the papacy and the authority of the Catholic Church hierarchy. Towards the end of the Renaissance, the Reformation marked the beginning of Protestantism. It is considered one of the events that signified the end of the Middle Ages and the beginning of the early modern period in Europe.

Monophysitism ( ) or monophysism ( ; from Greek , "solitary" and , "nature") is a Christological doctrine that states that there was only one nature—the divine—in the person of Jesus Christ, who was the incarnated Word. It is rejected as heretical by the Catholic Church, Eastern Orthodox Church, Anglicanism, Lutheranism, Reformed Christianity (Calvinist), and all mainstream Protestant denominations, which hold to the dyophysitism of the 451 Council of Chalcedon—as well by Oriental Orthodoxy, which holds to miaphysitism.

Donatism

Donatism was a schism from the Catholic Church in the Archdiocese of Carthage from the fourth to the sixth centuries. Donatists argued that Christian clergy must be faultless for their ministry to be effective and their prayers and sacraments to be valid. Donatism had its roots in the long-established Christian community of the Roman province Africa Proconsularis (present-day Tunisia, the northeast of Algeria, and the western coast of Libya) and M

monothelitism
Monothelitism, or monotheletism, is a theological doctrine in Christianity that was proposed in the 7th century, but was ultimately rejected by the sixth ecumenical council. It held Christ as having only one will and was thus contrary to dyothelitism, the Christological doctrine accepted by most Christian denominations, which holds Christ as having two wills (divine and human). Historically, monothelitism was closely related to monoenergism, a theological doctrine that holds Jesus Christ as having only one energy. Both doctrines were at the center of Christological disputes during the 7th cent
nontrinitarianism
Nontrinitarianism is a form of Christianity that rejects the Christian theology of the Trinity—the belief that God is three distinct hypostases or persons who are coeternal, coequal, and indivisibly united in one being, or essence (from the Ancient Greek ). Certain religious groups that emerged during the Protestant Reformation have historically been known as antitrinitarian.

Marcionism
Marcionism was an early Christian dualistic belief system originating with the teachings of Marcion of Sinope in Rome around 144. Marcion was an early Christian theologian, evangelist, and an important figure in early Christianity. He was the son of a bishop of Sinope in Pontus. About the middle of the 2nd century (140–155) he traveled to Rome, where he joined the Syrian gnostic Cerdo.
dyophysite
Dyophysitism (; from Greek δύο dyo, "two" and φύσις physis, "nature") is the Christological position that Jesus Christ is in two distinct, inseparable natures: divine and human. It is accepted by the majority of Christian denominations, including the Catholic Church, Eastern Orthodox Church, Church of the East, Anglicanism, Methodism, Reformed Christianity and Lutheranism. It is rejected by the Oriental Orthodox churches, who hold to Miaphysitism—that Jesus Christ is of two natures united into one composite nature—while rejecting Monophysitism as heresy along with other extant denominations.
Miaphysitism
Miaphysitism () is the Christological doctrine that holds Jesus, the Incarnate Word, is fully divine and fully human, in one nature or physis (). It is the position held by the Oriental Orthodox Churches. It differs from the dyophysitism of the Catholic Church, Eastern Orthodox Church, the Church of the East and major Protestant denominations, which holds that Jesus is one person with two natures (divine and human) as defined by the Council of Chalcedon in 451.

Novatianism
Novatianism or Novationism was an early Christian sect devoted to the theologian Novatian () that held a strict view that refused readmission to communion of lapsi (those baptized Christians who had denied their faith or performed the formalities of a ritual sacrifice to the pagan gods under the pressures of the persecution sanctioned by Emperor Decius in AD 250). The Church of Rome declared the Novatianists heretical following the letters of Saint Cyprian of Carthage and Ambrose wrote against them. Novatianism survived until the 8th century.

Quartodecimanism
Quartodecimanism (from the Vulgate Latin quarta decima in Leviticus 23:5, meaning fourteenth) is the name given to the practice of commemorating the death of Christ on the day of Passover, the 14th of Nisan according to biblical dating, on whatever day of the week it occurs. The Quartodeciman controversy in the Church was the question of whether to celebrate Easter on Sunday (the first day of the week), or at the time of sacrifice of the Passover lamb.

Alogi
thumb|right
The Alogi (), also called Alogoi or Alogians, were a group of heterodox Christians in Asia Minor that flourished c. 200 AD, and taught that the Gospel of John and the Apocalypse of John were not the work of the Apostle, but his adversary Cerinthus. What we know of them is derived from their doctrinal opponents, whose literature is extant, particularly Epiphanius of Salamis. It was Epiphanius who coined the name "Alogi" as a word play suggesting that they were both illogical and they were against the Christian doctrine of the Logos. While Epiphanius does not specifically indicate th

Judaizers
The Judaizers were a faction of the Jewish Christians, both of Jewish and non-Jewish origins, who regarded the Levitical laws of the Old Testament as still binding on all Christians. They tried to enforce Jewish circumcision upon the Gentile converts to early Christianity and were strenuously opposed and criticized for their behavior by the Apostle Paul, who employed many of his epistles to refute their doctrinal positions.

The Melitians, sometimes called the Church of the Martyrs, were an early Christian sect in Egypt. They were founded about 306 by Bishop Melitius of Lycopolis and survived as a small group into the eighth century. The point on which they broke with the larger catholic church was the same as that of the contemporary Donatists in the province of Africa: the ease with which lapsed Christians were received back into communion. The resultant division in the church of Egypt is known as the Melitian schism.
