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.
Sanctification in ChristianitySanctification (or in its verb form, sanctify) literally means "to set apart for special use or purpose", that is, to make holy or sacred (compare sanctus). Therefore, sanctification refers to the state or process of being set apart, i.e. "made holy", as a vessel, full of the Holy Spirit of God. The concept of sanctification is widespread among religions, including Judaism and especially Christianity.
Salvation in ChristianityIn Christianity, salvation (also called deliverance or redemption) is the saving of human beings from sin and its consequences—which include death and separation from God—by Christ's death and resurrection, and the justification entailed by this salvation. The idea of Jesus' death as an atonement for human sin was recorded in the Christian Bible, and was elaborated in Paul's epistles and in the Gospels. Paul saw the faithful redeemed by participation in Jesus' death and rising.
PurgatoryPurgatory ( purgatorium, borrowed into English via Anglo-Norman and Old French) is, according to the belief of some Christian denominations and Islam, an intermediate state after physical death for expiatory purification. The process of purgatory is the final purification of the elect, which is entirely different from the punishment of the damned. Tradition, by reference to certain texts of scripture, sees the process as involving a cleansing fire. Some forms of Western Christianity, particularly within Protestantism, deny its existence.
Good worksIn Christian theology, good works, or simply works, are a person's (exterior) actions or deeds, in contrast to inner qualities such as grace or faith. The Anglican theological tradition, including The Church of England, The Episcopal Church (United States), and others in the worldwide Anglican Communion as well as those who have broken away from communion but identify with the tradition, contains within it both Protestant and Catholic perspectives on this doctrine.
Christian ChurchIn ecclesiology, the Christian Church is what different Christian denominations conceive of as being the true body of Christians or the original institution established by Jesus. "Christian Church" has also been used in academia as a synonym for Christianity, despite the fact that it is composed of multiple churches or denominations, many of which hold a doctrinal claim of being the "one true church", to the exclusion of the others.
