Systematic theologySystematic theology, or systematics, is a discipline of Christian theology that formulates an orderly, rational, and coherent account of the doctrines of the Christian faith. It addresses issues such as what the Bible teaches about certain topics or what is true about God and His universe. It also builds on biblical disciplines, church history, as well as biblical and historical theology. Systematic theology shares its systematic tasks with other disciplines such as constructive theology, dogmatics, ethics, apologetics, and philosophy of religion.
ChristologyIn Christianity, Christology (from the Greek Khristós and -logia), translated from Greek as 'the study of Christ', is a branch of theology that concerns Jesus. Different denominations have different opinions on questions such as whether Jesus was human, divine, or both, and as a messiah what his role would be in the freeing of the Jewish people from foreign rulers or in the prophesied Kingdom of God, and in the salvation from what would otherwise be the consequences of sin.
ChristadelphiansThe Christadelphians (ˌkrɪstəˈdɛlfiənz) are a restorationist group that hold a view of biblical unitarianism. There are approximately 50,000 Christadelphians in around 120 countries. The movement developed in the United Kingdom and North America in the 19th century around the teachings of John Thomas, who coined the name Christadelphian from the Greek words for Christ (Christos) and brothers (adelphoi). Asserting the Bible as the sole basis of their beliefs, Christadelphians differ from mainstream Christianity in a number of doctrinal areas.
Johannine CommaThe Johannine Comma (Comma Johanneum) is an interpolated phrase (comma) in verses of the First Epistle of John. The text (with the comma in italics and enclosed by square brackets) in the King James Bible reads: ^7For there are three that beare record [] ^8[], the Spirit, and the Water, and the Blood, and these three agree in one. It became a touchpoint for the Christian theological debate over the doctrine of the Trinity from the early church councils to the Catholic and Protestant disputes in the early modern period.
Covenant theologyCovenant theology (also known as covenantalism, federal theology, or federalism) is a conceptual overview and interpretive framework for understanding the overall structure of the Bible. It uses the theological concept of a covenant as an organizing principle for Christian theology. The standard form of covenant theology views the history of God's dealings with mankind, from Creation to Fall to Redemption to Consummation, under the framework of three overarching theological covenants: those of redemption, of works, and of grace.
New JerusalemIn the Book of Ezekiel in the Hebrew Bible, New Jerusalem (, YHWH šāmmā, YHWH [is] there") is Ezekiel's prophetic vision of a city centered on the rebuilt Holy Temple, the Third Temple, to be established in Jerusalem, which would be the capital of the Messianic Kingdom, the meeting place of the twelve tribes of Israel, during the Messianic era. The prophecy is recorded by Ezekiel as having been received on Yom Kippur of the year 3372 of the Hebrew calendar.
Irresistible graceIrresistible grace (also called effectual grace, effectual calling, or efficacious grace) is a doctrine in Christian theology particularly associated with Calvinism, which teaches that the saving grace of God is effectually applied to those whom he has determined to save (the elect) and, in God's timing, overcomes their resistance to obeying the call of the gospel, bringing them to faith in Christ.
Diodorus of TarsusDiodore of Tarsus (Greek Διόδωρος ὁ Ταρσεύς; died c. 390) was a Christian bishop, a monastic reformer, and a theologian. A strong supporter of the orthodoxy of Nicaea, Diodore played a pivotal role in the Council of Constantinople and opposed the anti-Christian policies of Julian the Apostate. Diodore founded one of the most influential centers of Christian thought in the early church, and many of his students became notable theologians in their own right. Diodore was born into a noble family in the area of Antioch.
Heresy in ChristianityHeresy in Christianity denotes the formal denial or doubt of a core doctrine of the Christian faith as defined by one or more of the Christian churches. The study of heresy requires an understanding of the development of orthodoxy and the role of creeds in the definition of orthodox beliefs, since heresy is always defined in relation to orthodoxy. Orthodoxy has been in the process of self-definition for centuries, defining itself in terms of its faith by clarifying beliefs in opposition to people or doctrines that are perceived as incorrect.
Penal substitutionPenal substitution (sometimes, esp. in older writings, called forensic theory) is a theory of the atonement within Protestant Christian theology, which declares that Christ, voluntarily submitting to God the Father's plan, was punished (penalized) in the place of sinners (substitution), thus satisfying the demands of justice so God can justly forgive sins making us at one with God (atonement). It began with the German Reformation leader Martin Luther and continued to develop within the Calvinist tradition as a specific understanding of substitutionary atonement.
