DeciusGaius Messius Quintus Trajanus Decius ( 201 AD - June 251 AD), sometimes translated as Trajan Decius or Decius, was the emperor of the Roman Empire from 249 to 251. A distinguished politician during the reign of Philip the Arab, Decius was proclaimed emperor by his troops after putting down a rebellion in Moesia. In 249, he defeated and killed Philip near Verona and was recognized as emperor by the Senate afterwards.
SabellianismIn Christianity, Sabellianism is the Eastern Church equivalent to Patripassianism in the Western Church, which are both forms of theological modalism. Condemned as heresy, Modalism is the belief that the Father, Son and Holy Spirit are three different modes of God, as opposed to a Trinitarian view of three distinct persons within the Godhead. However, Von Mosheim, German Lutheran theologian who founded the pragmatic school of church historians, argues that Sabellius "believed the distinction of Father, Son, and Holy Spirit, described in the Scriptures, to be a real distinction, and not a mere appellative or nominal one.
TrinityThe Christian doctrine of the Trinity (Trinitas, from trinus 'threefold') is the central doctrine concerning the nature of God in most Christian churches, which defines one God existing in three , , consubstantial divine persons: God the Father, God the Son (Jesus Christ) and God the Holy Spirit, three distinct persons (hypostases) sharing one essence/substance/nature (homoousion) As the Fourth Lateran Council declared, it is the Father who s, the Son who is , and the Holy Spirit who proceeds.
Infant baptismInfant baptism (or paedobaptism) is the practice of baptising infants or young children. Infant baptism is also called christening by some faith traditions. Most Christians belong to denominations that practice infant baptism. Branches of Christianity that practice infant baptism include Catholicism, Eastern Orthodoxy, and Oriental Orthodoxy. Among Protestants, several denominations practice infant baptism including Anglicans, Lutherans, Presbyterians, Congregationalists, Methodists, Nazarenes, Moravians, and United Protestants.
DidacheThe Didache (ˈdɪdəkeː,_-ki; Didakhé), also known as The Lord's Teaching Through the Twelve Apostles to the Nations (Διδαχὴ Κυρίου διὰ τῶν δώδεκα ἀποστόλων τοῖς ἔθνεσιν), is a brief anonymous early Christian treatise (ancient church order) written in Koine Greek, dated by modern scholars to the first or (less commonly) second century AD. The first line of this treatise is: "The teaching of the Lord to the Gentiles (or Nations) by the twelve apostles".
Doctor of the ChurchDoctor of the Church (Latin: doctor "teacher"), also referred to as Doctor of the Universal Church (Latin: Doctor Ecclesiae Universalis), is a title given by the Catholic Church to saints recognized as having made a significant contribution to theology or doctrine through their research, study, or writing. But more importantly, a Doctor of the Church is one who has been officially recognized by the Roman Catholic Church for having lived a very holy, humble, self-mortifying, sacrificial life, and having been a stout defender of orthodoxy.
Confessor of the FaithConfessor of the Faith is a title given by some Christian denominations. In Catholicism and Eastern Orthodoxy, Christians who professed their faith in times of Christian persecution and therefore had to suffer persecution, expulsion, torture, mutilation and imprisonment, but not directly undergo martyrdom, are called confessors (confessores). Later, popes, bishops, abbots, kings and hermits were also counted among the confessors.
Decian persecutionThe Decian persecution of Christians occurred in 250 AD under the Roman Emperor Decius. He had issued an edict ordering everyone in the Empire to perform a sacrifice to the Roman gods and the well-being of the emperor. The sacrifices had to be performed in the presence of a Roman magistrate, and be confirmed by a signed and witnessed certificate from the magistrate. Although the text of the edict has been lost, many examples of the certificates have survived.
NovatianismNovatianism or Novationism was an early Christian sect devoted to the theologian Novatian ( 200–258) 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.
NovatianNovatian (200-258) was a scholar, priest, and theologian. He is considered by the Catholic Church to have been an antipope between 251 and 258. Some Greek authors give his name as Novatus, who was an African presbyter. He was a noted theologian and writer, the first Roman theologian who used the Latin language, at a time when there was much debate about how to deal with Christians who had lapsed and wished to return, and the issue of penance. Consecrated as pope by three bishops in 251, he adopted a more rigorous position than the established Pope Cornelius.
