Christ in the context of "Promptuarium Iconum Insigniorum"

The Barberini ivory is a Byzantine ivory leaf from an imperial diptych dating from Late Antiquity, now in the Louvre in Paris. It represents the emperor as triumphant victor. It is generally dated from the first half of the 6th century and is attributed to an imperial workshop in Constantinople, while the emperor is usually identified as Justinian, or possibly Anastasius I or Zeno. It is a notable historical document because it is linked to queen Brunhilda of Austrasia. On the back there is a list of names of Frankish kings, all relatives of Brunhilda, indicating her important position. Brunhilda ordered the list to be inscribed and offered it to the church as a votive image.

Although it is not a consular diptych, it shares many features of their decorative schemes. The emperor is accompanied in the main panel by a conquered barbarian in trousers at left, a crouching allegorical figure, probably representing territory conquered or reconquered, who holds his foot in thanks or submission, and an angel or victory, crowning the emperor with the traditional palm of victory (which is now lost). Although the barbarian is partly hidden by the emperor's huge spear, this does not pierce him, and he seems more astonished and over-awed than combative. Above, Christ, with a fashionable curled hair-style, is flanked by two more angels in the style of pagan victory figures; he reigns above, while the emperor represents him below on earth. In the bottom panel barbarians from West (left, in trousers) and East (right, with ivory tusks, a tiger and a small elephant) bring tribute, which includes wild animals. The figure in the left panel, representing a soldier, carries a statuette of Victory; his counterpart on the right is lost.

The primacy of Peter, also known as Petrine primacy (from the Latin: Petrus, lit. 'Peter'), is the position of preeminence that is attributed to Peter among the Twelve Apostles.

Autokrator or Autocrator (Ancient Greek: αὐτοκράτωρ, romanized: autokrátōr, lit. 'self-ruler', from αὐτός, autós, 'self' + κράτος, krátos, 'dominion') is a Greek epithet applied to an individual who is unrestrained by superiors. It has been applied to military commanders-in-chief as well as Roman and Byzantine emperors as the translation of the Latin title imperator. Its connection with Byzantine and Russian-style absolutism gave rise to the modern terms autocracy and autocrat.

The Chalcedonian schism, also known as the Monophysite schism, is the break of communion between the Oriental Orthodox Churches and the Great Church (which later became the Eastern Orthodox Church and Catholic Church) in the aftermath of the Council of Chalcedon. Although the bishops at Chalcedon greatly respected Cyril of Alexandria and used his writings as a benchmark for orthodoxy, opponents of the council believed that the Chalcedonian Definition, which states that Christ is "acknowledged in Two Natures", was too close to Nestorianism and contradicts Cyril's formula "one nature of God the Word incarnate". The Council had also deposed the Pope of Alexandria, Dioscorus, but his supporters continued to consider him their rightful Pope, refusing to recognise the council-appointed Proterius.

The anti-Chalcedonian strongholds were in Egypt, Palestine and later Syria. Over the next century, their communities gradually separated from the official church of the Byzantine Empire, eventually becoming the Oriental Orthodox Churches. The imperial government made many attempts to mend the schism, generally by trying to compromise between the two positions, but these attempts only created further heresies and schisms. The Arab conquests of the Levant and of Egypt in the 7th century fossilised the schism, but ecumenical dialogue between Chalcedonian and non-Chalcedonian Christians has been renewed since the 20th century.

Sacramental bread, also called Communion bread, Communion wafer, Sacred host, Eucharistic bread, the Lamb or simply the host (Latin: hostia, lit. 'sacrificial victim'), is the bread used in the Christian ritual of the Eucharist and the body of Christ. Along with sacramental wine, it is one of two elements of the Eucharist. The bread may be either leavened or unleavened, depending on tradition.

Catholic theology generally teaches that at the Words of Institution the bread's substance is changed into the Body of Christ, a process known as transubstantiation. Conversely, Eastern Christian theology generally views the epiclesis as the point at which the change occurs.

God-man (Koine Greek: θεάνθρωπος, romanized: theánthropos; Latin: deus homo) is a term which refers to the incarnation and the hypostatic union of Christ, which are two of mainstream Christianity's most widely accepted and revered christological doctrines.

Anointing is the ritual act of pouring aromatic oil over a person's head or entire body. By extension, the term is also applied to related acts of sprinkling, dousing, or smearing a person or object with any perfumed oil, milk, butter, or other fat. Scented oils are used as perfumes and sharing them is an act of hospitality. Their use to introduce a divine influence or presence is recorded from the earliest times; anointing was thus used as a form of medicine, thought to rid persons and things of dangerous spirits and demons which were believed to cause disease.

In present usage, "anointing" is typically used for ceremonial blessings such as the coronation of European monarchs. This continues an earlier Hebrew practice most famously observed in the anointings of Aaron as high priest and both Saul and David by the prophet Samuel. The concept is important to the figure of the Messiah or the Christ (Hebrew and Greek for "The Anointed One") who appear prominently in Jewish and Christian theology and eschatology. Anointing—particularly the anointing of the sick—may also be known as unction; the anointing of the dying as part of last rites in the Catholic church is sometimes specified as "extreme unction".

Scivias is an illustrated work by Hildegard von Bingen, completed in 1151 or 1152, describing 26 religious visions she experienced. It is the first of three works that she wrote describing her visions, the others being Liber vitae meritorum and De operatione Dei (also known as Liber divinorum operum). The title comes from the Latin phrase Sci vias Domini ('Know the Ways of the Lord'). The book is illustrated by 35 miniature illustrations, more than that are included in her two later books of visions.

The work is divided into three parts, reflecting the Trinity. The first and second parts are approximately equal in length, while the third is as long as the other two together. The first part includes a preface describing how she was commanded to write the work, and includes six visions dealing with themes of creation and the Fall. The second part consists of seven visions and deals with salvation through Jesus Christ, the Church, and the sacraments. The third part, with thirteen visions, is about the coming kingdom of God, through sanctification, and increased tension between good and evil. The final vision includes 14 songs, plus a portion of the music drama which was later published as the Ordo Virtutum. In each vision, she first described what she saw, and then recorded explanations she heard, which she believed to be the "voice of heaven."
