Arianism is a Christological doctrine considered heretical by all modern mainstream branches of Christianity. It is first attributed to Arius, a Christian presbyter who preached and studied in Alexandria, Egypt. Arian theology holds that Jesus Christ is the Son of God, who was begotten by God the Father with the difference that the Son of God did not always exist but was begotten/made before time by God the Father; therefore, Jesus was not coeternal with God the Father, but nonetheless Jesus began to exist outside time.
Eusebius of Nicomedia was an Arian priest who baptized Constantine the Great on his deathbed in 337. A fifth-century legend evolved that Pope Sylvester I was the one to baptize Constantine, but this is dismissed by scholars as a forgery 'to amend the historical memory of the Arian baptism that the emperor received at the end of his life, and instead to attribute an unequivocally orthodox baptism to him.' He was a bishop of Berytus in Phoenicia. He was later made the bishop of Nicomedia, where the Imperial court resided. He lived finally in Constantinople from 338 up to his death.
Filioque, a Latin term meaning "and from the Son", was added to the original Nicene Creed, and has been the subject of great controversy between Eastern and Western Christianity. The term refers to the Son, Jesus Christ, with the Father, as the one shared origin of the Holy Spirit. It is not in the original text of the Creed, attributed to the First Council of Constantinople (381), which says that the Holy Spirit proceeds "from the Father" without the addition "and the Son".
The First Council of Constantinople was a council of Christian bishops convened in Constantinople in AD 381 by the Roman Emperor Theodosius I. This second ecumenical council, an effort to attain consensus in the church through an assembly representing all of Christendom, except for the Western Church, confirmed the Nicene Creed, expanding the doctrine thereof to produce the Niceno-Constantinopolitan Creed, and dealt with sundry other matters. It met from May to July 381 in the Church of Hagia Irene and was affirmed as ecumenical in 451 at the Council of Chalcedon.
The Nicene Creed, also called the Creed of Constantinople, is the defining statement of belief of mainstream Christianity and in those Christian denominations that adhere to it. The original Nicene Creed was first adopted at the First Council of Nicaea in 325. According to a popular view forwarded by the Council of Chalcedon of 451, the Creed was amended in 381 by the First Council of Constantinople as "consonant to the holy and great Synod of Nice." However, there are some who comment on these ancient Councils who say "there is a failure of evidence" for this position since no one between the years of 381–451 thought of it in this light. Nonetheless, the amended form is presently referred to as the Nicene Creed or the Niceno-Constantinopolitan Creed.
Reccared I was Visigothic King of Hispania and Septimania. His reign marked a climactic shift in history, with the king's renunciation of Arianism in favour of Roman Christianity in 587.
Leander of Seville was a Hispano-Roman Catholic prelate who served as Bishop of Seville. He was instrumental in effecting the conversion of the Visigothic kings Hermenegild and Reccared to Chalcedonian Christianity. His brother was the encyclopedist Isidore of Seville.
Saint Hermenegild or Ermengild, was the son of King Liuvigild of the Visigothic Kingdom in the Iberian Peninsula and southern France. He fell out with his father in 579, then revolted the following year. During his rebellion, he converted from Arianism to Chalcedonian Christianity. Hermenegild was defeated in 584 and exiled. His death was later celebrated as a martyrdom due to the influence of Pope Gregory I's Dialogues, in which he portrayed Hermenegild as a "Catholic martyr rebelling against the tyranny of an Arian father."
The Acacians, or perhaps better described as the Homoians or Homoeans, were a non-Nicene branch of Christianity that dominated the church during much of the fourth-century Arian Controversy. They declared that the Son was similar to God the Father, without reference to substance (essence). Homoians played a major role in the Christianization of the Goths in the Danubian provinces of the Roman Empire.
Liuvigild, Leuvigild, Leovigild, or Leovigildo, was a Visigothic King of Hispania and Septimania from 568 to 586. Known for his Codex Revisus or Code of Leovigild, a law allowing equal rights between the Visigothic and Hispano-Roman population, his kingdom covered modern Portugal and most of modern Spain down to Toledo. Liuvigild ranks among the greatest Visigothic kings of the Arian period.
Gothic Christianity refers to the Christian religion of the Goths and sometimes the Gepids, Vandals, and Burgundians, who may have used the translation of the Bible into the Gothic language and shared common doctrines and practices.
The Visigothic Kingdom, Visigothic Spain or Kingdom of the Goths occupied what is now southwestern France and the Iberian Peninsula from the 5th to the 8th centuries. One of the Germanic successor states to the Western Roman Empire, it was originally created by the settlement of the Visigoths under King Wallia in the province of Gallia Aquitania in southwest Gaul by the Roman government and then extended by conquest over all of Hispania. The Kingdom maintained independence from the Eastern Roman or Byzantine Empire, whose attempts to re-establish Roman authority in Hispania were only partially successful and short-lived.
Masona or Mausona was the Bishop of Mérida and metropolitan of the province of Lusitania from about 570 until his death. He is famous for exercising de facto rule of the city of Mérida during his tenure as bishop and for founding the first confirmed hospital in Spain.
Athaloc was the Visigothic Arian Archbishop of Narbonne at the time of the Third Council of Toledo in 589. He was the metropolitan of his province in parallel with the Catholic hierarchy.
In the history of Christianity, the first seven ecumenical councils include the following: the First Council of Nicaea in 325, the First Council of Constantinople in 381, the Council of Ephesus in 431, the Council of Chalcedon in 451, the Second Council of Constantinople in 553, the Third Council of Constantinople from 680 to 681 and finally, the Second Council of Nicaea in 787. All of the seven councils were convened in what is now the country of Turkey.
Christianity in the 4th century was dominated in its early stage by Constantine the Great and the First Council of Nicaea of 325, which was the beginning of the period of the First seven Ecumenical Councils (325–787), and in its late stage by the Edict of Thessalonica of 380, which made Nicene Christianity the state church of the Roman Empire.
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 late antiquity traces Christianity during the Christian Roman Empire — the period from the rise of Christianity under Emperor Constantine, until the fall of the Western Roman Empire. The end-date of this period varies because the transition to the sub-Roman period occurred gradually and at different times in different areas. One may generally date late ancient Christianity as lasting to the late 6th century and the re-conquests under Justinian of the Byzantine Empire, though a more traditional end-date is 476, the year in which Odoacer deposed Romulus Augustus, traditionally considered the last western emperor.
The history of Eastern Orthodox Christian theology begins with the life of Jesus and the forming of the Christian Church. Major events include the Chalcedonian schism of 451 with the Oriental Orthodox miaphysites, the Iconoclast controversy of the 8th and 9th centuries, the Photian schism (863-867), the Great Schism between East and West, and the Hesychast controversy. The period after the end of the Second World War in 1945 saw a re-engagement with the Greek, and more recently Syriac Fathers that included a rediscovery of the theological works of St. Gregory Palamas, which has resulted in a renewal of Orthodox theology in the 20th and 21st centuries.
Ingunde, Ingund, Ingundis or Ingunda, was the eldest child of Sigebert I, king of Austrasia, and his wife Brunhilda, daughter of King Athanagild of the Visigoths. She married Hermenegild and became the first Catholic queen of the Visigoths.
