Pauline epistlesThe Pauline epistles, also known as Epistles of Paul or Letters of Paul, are the thirteen books of the New Testament attributed to Paul the Apostle, although the authorship of some is in dispute. Among these epistles are some of the earliest extant Christian documents. They provide an insight into the beliefs and controversies of early Christianity. As part of the canon of the New Testament, they are foundational texts for both Christian theology and ethics.
ApologeticsApologetics (from Greek ἀπολογία, "speaking in defense") is the religious discipline of defending religious doctrines through systematic argumentation and discourse. Early Christian writers (c. 120–220) who defended their beliefs against critics and recommended their faith to outsiders were called Christian apologists. In 21st-century usage, apologetics is often identified with debates over religion and theology. The term apologetics derives from the Ancient Greek word apologia (ἀπολογία).
Augustine of HippoAugustine of Hippo (ɔːˈɡʌstᵻn , USalsoˈɔːɡəstiːn ; Aurelius Augustinus Hipponensis; 13 November 354 – 28 August 430), also known as Saint Augustine, was a theologian and philosopher of Berber origin and the bishop of Hippo Regius in Numidia, Roman North Africa. His writings influenced the development of Western philosophy and Western Christianity, and he is viewed as one of the most important Church Fathers of the Latin Church in the Patristic Period. His many important works include The City of God, On Christian Doctrine, and Confessions.
GnosticismGnosticism (from Ancient Greek: γνωστικός, romanized: gnōstikós, Koine Greek: [ɣnostiˈkos], 'having knowledge') is a collection of religious ideas and systems that coalesced in the late 1st century AD among Jewish and early Christian sects. These various groups emphasized personal spiritual knowledge (gnosis) above the proto-orthodox teachings, traditions, and authority of religious institutions. Gnostic cosmogony generally presents a distinction between a supreme, hidden God and a malevolent lesser divinity (sometimes associated with the God of the Hebrew Bible) who is responsible for creating the material universe.
Marcion of SinopeMarcion of Sinope (ˈmɑrkiən,_-siən; Μαρκίων Σινώπης; 85-160) was an early Christian theologian in early Christianity. Marcion preached that God had sent Jesus Christ, who was an entirely new, alien god, distinct from the "vengeful" God (Demiurge) who had created the world. He considered himself a follower of Paul the Apostle, whom he believed to have been the only true apostle of Jesus Christ; his doctrine is called Marcionism. Marcion published the earliest record of a canon of New Testament books.
HeresyHeresy is any belief or theory that is strongly at variance with established beliefs or customs, particularly the accepted beliefs or religious law of a religious organization. A heretic is a proponent of heresy. Heresy in Christianity, Judaism, and Islam has at times been met with censure ranging from excommunication to the death penalty. Heresy is distinct from apostasy, which is the explicit renunciation of one's religion, principles or cause; and from blasphemy, which is an impious utterance or action concerning God or sacred things.
OusiaOusia (ˈuːziə,_ˈuːsiə,_ˈuːʒə,_ˈuːʃə; οὐσία) is a philosophical and theological term, originally used in ancient Greek philosophy, then later in Christian theology. It was used by various ancient Greek philosophers, like Plato and Aristotle, as a primary designation for philosophical concepts of essence or substance. In contemporary philosophy, it is analogous to English concepts of being and ontic. In Christian theology, the concept of θεία ουσία (divine essence) is one of the most important doctrinal concepts, central to the development of trinitarian doctrine.
Epistle to the ColossiansThe Epistle to the Colossians is the twelfth book of the New Testament. It was written, according to the text, by Paul the Apostle and Timothy, and addressed to the church in Colossae, a small Phrygian city near Laodicea and approximately from Ephesus in Asia Minor. Some scholars have increasingly questioned Paul's authorship and attributed the letter to an early follower instead, but others still defend it as authentic. If Paul was the author, he probably used an amanuensis, or secretary, in writing the letter (Col 4:18), possibly Timothy.
Book of TobitThe Book of Tobit (ˈtoʊbɪt), also known as the Book of Tobias or the Book of Tobi, is a 3rd or early 2nd century BC Jewish work describing how God tests the faithful, responds to prayers, and protects the covenant community (i.e., the Israelites). It tells the story of two Israelite families, that of the blind Tobit in Nineveh and of the abandoned Sarah in Ecbatana. Tobit's son Tobias is sent to retrieve ten silver talents that Tobit once left in Rages, a town in Media; guided and aided by the angel Raphael he arrives in Ecbatana, where he meets Sarah.
Epistle of BarnabasThe Epistle of Barnabas (Βαρνάβα Ἐπιστολή) is a Greek epistle written between AD 70 and 132. The complete text is preserved in the 4th-century Codex Sinaiticus, where it appears immediately after the New Testament and before the Shepherd of Hermas. For several centuries it was one of the "antilegomena" ("disputed") writings that some Christians looked on as sacred scripture, while others excluded them. Eusebius of Caesarea classified it as such.
