Middle Ages

The persecution of Christians can be traced from the first century of the Christian era to the present day. Christian missionaries and converts to Christianity have both been targeted for persecution, sometimes to the point of being martyred for their faith, ever since the emergence of Christianity.

Early Christians were persecuted at the hands of both Jews, from whose religion Christianity arose, and the Romans who controlled many of the early centers of Christianity in the Roman Empire. Since the emergence of Christian states in Late Antiquity, Christians have also been persecuted by other Christians due to differences in doctrine which have been declared heretical. Early in the fourth century, the empire's official persecutions were ended by the Edict of Serdica in 311 and the practice of Christianity legalized by the Edict of Milan in 312. By the year 380, Christians had begun to persecute each other. The schisms of late antiquity and the Middle Ages – including the Rome–Constantinople schisms and the many Christological controversies – together with the later Protestant Reformation provoked severe conflicts between Christian denominations. During these conflicts, members of the various denominations frequently persecuted each other and engaged in sectarian violence.

The Slavic Native Faith, commonly known as Rodnovery and sometimes as Slavic Neopaganism, is a modern Pagan religion. Classified as a new religious movement, its practitioners hearken back to the historical belief systems of the Slavic peoples of Central and Eastern Europe, though the movement is inclusive of external influences and hosts a variety of currents. "Rodnovery" is a widely accepted self-descriptor within the community, although there are Rodnover organisations which further characterise the religion as Vedism, Orthodoxy, and Old Belief.

Many Rodnovers regard their religion as a faithful continuation of the ancient beliefs that survived as a folk religion or a conscious "double belief" following the Christianisation of the Slavs in the Middle Ages. Rodnovery draws upon surviving historical and archaeological sources and folk religion, often integrating them with non-Slavic sources such as Hinduism (because they are believed to come from the same Proto-Indo-European source). Rodnover theology and cosmology may be described as henotheism and polytheism—worship of the supreme God of the universe and worship of the multiple gods, the ancestors and the spirits of nature who are identified in Slavic culture. Adherents of Rodnovery usually meet in groups in order to perform religious ceremonies. These ceremonies typically entail the invocation of gods, the offering of sacrifices and the pouring of libations, dances and communal meals.

The Syriac language (/ˈsɪriæk/ SIRR-ee-ak; Classical Syriac: ܠܫܢܐ ܣܘܪܝܝܐ, romanized: Leššānā Suryāyā), also known natively in its spoken form in early Syriac literature as Edessan (Urhāyā), the Mesopotamian language (Nahrāyā) and Aramaic (Aramāyā), is an Eastern Middle Aramaic dialect. Classical Syriac is the academic term used to refer to the dialect's literary usage and standardization, distinguishing it from other Aramaic dialects also known as 'Syriac' or 'Syrian'. In its West-Syriac tradition, Classical Syriac is often known as leššōnō kṯoḇonōyō (lit. 'the written language or the book language') or simply kṯoḇonōyō, or kṯowonōyō, while in its East-Syriac tradition, it is known as leššānā ʔatīqā (lit. 'the old language') or saprāyā (lit. 'scribal or literary').

It emerged during the first century AD from a local Eastern Aramaic dialect that was spoken in the ancient region of Osroene, centered in the city of Edessa. During the Early Christian period, it became the main literary language of various Aramaic-speaking Christian communities in the historical region of Ancient Syria and throughout the Near East. As a liturgical language of Syriac Christianity, it gained a prominent role among Eastern Christian communities that used both Eastern Syriac and Western Syriac rites. Following the spread of Syriac Christianity, it also became a liturgical language of eastern Christian communities as far as India and China. It flourished from the 4th to the 8th century, and continued to have an important role during the next centuries, but by the end of the Middle Ages it was gradually reduced to liturgical use, since the role of vernacular language among its native speakers was overtaken by several emerging Neo-Aramaic languages.

The Old Yishuv (Hebrew: היישוב הישן, haYishuv haYashan) were the Jewish communities of the region of Palestine during the Ottoman period, up to the onset of Zionist aliyah waves, and the consolidation of the new Yishuv by the end of World War I. Unlike the new Yishuv, characterized by secular and Zionist ideologies promoting labor and self-sufficiency, the Old Yishuv primarily consisted of religious Jews who relied on external donations (halukka) for support.

The Old Yishuv evolved following a significant decline in Jewish communities across the region during late antiquity and the early Middle Ages, and was composed of three clusters. Firstly, Ladino-speaking Sephardic Jewish communities settled in the region during the late Mamluk and early Ottoman periods, alongside Arabic-speaking Musta'arabi communities, who had already been living there since before the coming of Islam and had been culturally and linguistically Arabized. Secondly, Ashkenazi Jews emigrated from Europe in the 18th and early 19th centuries, forming another group. A third wave of Yishuv members arrived in the late 19th century, hailing from Europe, North Africa, Yemen, Persia, and the Caucasus. These migrations gave rise to two distinct communities within the Old Yishuv—the Sephardim (including Musta'arabim) and the Askhenazim.

In Catholic tradition, the Five Holy Wounds, also known as the Five Sacred Wounds or the Five Precious Wounds, are the five piercing wounds that Jesus Christ suffered during his crucifixion. The wounds have been the focus of particular devotions, especially in the late Middle Ages, and have often been reflected in church music and art.

Apocalyptic literature is a genre of prophetical writing that developed in post-Exilic Jewish culture and was popular among millennialist early Christians. Apocalypse (Ancient Greek: ἀποκάλυψις, romanized: apokálupsis) is a Greek word meaning "revelation", "an unveiling or unfolding of things not previously known and which could not be known apart from the unveiling".

As a genre, apocalyptic literature details the authors' visions of the end times/end of the age as revealed by an angel or other heavenly messenger. The apocalyptic literature of Judaism and Christianity embraces a considerable period, from the centuries following the Babylonian exile down to the close of the Middle Ages.

A wax tablet is a tablet made of wood and covered with a layer of wax, often linked loosely to a cover tablet, as a "double-leaved" diptych. It was used as a reusable and portable writing surface in antiquity and throughout the Middle Ages. Cicero's letters make passing reference to the use of cerae, and some examples of wax-tablets have been preserved in waterlogged deposits in the Roman fort at Vindolanda on Hadrian's Wall. Medieval wax tablet books are on display in several European museums.

Writing on the wax surface was performed with a pointed instrument, a stylus. A straight-edged spatula-like implement (often placed on the opposite end of the stylus tip) would be used as an eraser. The modern expression of "a clean slate" equates to the Latin expression "tabula rasa".

The Catholic Church is the largest non-government provider of health care services in the world. It has around 18,000 clinics, 16,000 homes for the elderly and those with special needs, and 5,500 hospitals, with 65 percent of them located in developing countries. In 2010, the Church's Pontifical Council for the Pastoral Care of Health Care Workers said that the Church manages 26% of the world's health care facilities. The Church's involvement in health care has ancient origins.

Jesus Christ, whom the Church holds as its founder, instructed his followers to heal the sick. The early Christians were noted for tending the sick and infirm, and Christian emphasis on practical charity gave rise to the development of systematic nursing and hospitals. The influential Benedictine rule holds that "the care of the sick is to be placed above and before every other duty, as if indeed Christ were being directly served by waiting on them". During the Middle Ages, monasteries and convents were the key medical centres of Europe and the Church developed an early version of a welfare state. Cathedral schools evolved into a well integrated network of medieval universities and Catholic scientists (many of them clergymen) made a number of important discoveries which aided the development of modern science and medicine.

In the Middle Ages, the term universal power referred to the Holy Roman Emperor and the Pope. Both were struggling for the so-called dominium mundi, or world dominion, in terms of political and spiritual supremacy.

The universal powers continued into the early 19th century until the Napoleonic Wars. The reshaping of Europe meant the effective end of the Empire. Although the Papacy had its territorial limits confined to the Vatican, it retained its soft power in the contemporary world.

A use, also commonly usage (Latin: usum) and recension, within Christian liturgy is a set of particular texts or customs distinct from other practitioners of a broader liturgical ritual family, typically on the basis of locality or religious order. Especially prevalent within the Latin liturgical rites of the Middle Ages, few significant uses persisted following a general suppression of these variations by Pope Pius V in the 16th century. The word "use" is most commonly applied to distinct practices branching from the Roman Rite, though it and "recension" can be applied in variations of other ritual families, such as the Ruthenian recension of the Byzantine Rite, the Maronite Use of the West Syriac Rite and the Syro-Malabar Use of the East Syriac Rite. In the historic context of the Scottish Episcopal Church, "usage" refers to certain aspects of the Eucharistic liturgy valued by some nonjurors.
