An icon is a religious work of art, most commonly a painting, in the cultures of the Eastern Orthodox, Oriental Orthodox, and Catholic churches. They are not simply artworks; "an icon is a sacred image used in religious devotion". The most common subjects include Jesus, Mary, saints and angels. Although especially associated with portrait-style images concentrating on one or two main figures, the term also covers most of the religious images in a variety of artistic media produced by Eastern Christianity, including narrative scenes, usually from the Bible or the lives of saints.

Pope Marcellinus was the bishop of Rome from 30 June 296 to his death in 304. A historical accusation was levelled at him by some sources to the effect that he might have renounced Christianity during Emperor Diocletian's persecution of Christians before repenting afterwards, which would explain why he is omitted from lists of martyrs. The accusation is rejected, among others, by Augustine of Hippo. He is today venerated as a saint in the Catholic Church and in the Serbian Orthodox Church.

Catholic matrimonial law, based on Roman law regarding its focus on marriage as a free mutual agreement or contract, became the basis for the marriage law of all European countries, at least up to the Reformation.

In Christianity, a Eucharistic miracle is any miracle involving the Eucharist. The Roman Catholic, Lutheran, Oriental Orthodox, Eastern Orthodox, Moravian and Anglican Churches believe that Christ is really made manifest in the Eucharist and deem this a Eucharistic miracle; however, this is to be distinguished from other manifestations of God. The Catholic Church distinguishes between divine revelation, such as the Eucharist, and private revelation, such as Eucharistic miracles. In general, reported Eucharistic miracles usually consist of unexplainable phenomena such as consecrated Hosts visibly transforming into myocardium tissue, being preserved for extremely long stretches of time, surviving being thrown into fire, bleeding, or even sustaining people for decades.

In the 5th century in Christianity, there were many developments which led to further fracturing of the State church of the Roman Empire. Emperor Theodosius II called two synods in Ephesus, one in 431 and one in 449, that addressed the teachings of Patriarch of Constantinople Nestorius and similar teachings. Nestorius had taught that Christ's divine and human nature were distinct persons, and hence Mary was the mother of Christ but not the mother of God. The Council rejected Nestorius' view causing many churches, centered on the School of Edessa, to a Nestorian break with the imperial church. Persecuted within the Roman Empire, many Nestorians fled to Persia and joined the Sassanid Church thereby making it a center of Nestorianism. By the end of the 5th century, the global Christian population was estimated at 10-11 million. In 451 the Council of Chalcedon was held to clarify the issue further. The council ultimately stated that Christ's divine and human nature were separate but both part of a single entity, a viewpoint rejected by many churches who called themselves miaphysites. The resulting schism created a communion of churches, including the Armenian, Syrian, and Egyptian churches, that is today known as Oriental Orthodoxy. In spite of these schisms, however, the imperial church still came to represent the majority of Christians within the Roman Empire.
Christianity in the 8th century was much affected by the rise of Islam in the Middle East.
