Inaugurated eschatology in the context of "Eternal life (Christianity)"

The Kingdom of God (and its related form the Kingdom of Heaven in the Gospel of Matthew) is one of the key elements of the teachings of Jesus in the New Testament. Drawing on Old Testament teachings, the Christian characterization of the relationship between God and humanity inherently involves the notion of the Kingship of God. The Old Testament refers to "God the Judge of all" and the notion that all humans will eventually "be judged" is an essential element of Christian teachings. Building on a number of New Testament passages, the Nicene Creed indicates that the task of judgment is assigned to Jesus.

The New Testament is written against the backdrop of Second Temple Judaism. The view of the kingdom developed during that time included the restoration of Israel to a Davidic Kingdom and the intervention of God in history via the Danielic Son of Man. The coming of the kingdom of God involved God finally taking back the reins of history, which he had allowed to slacken as pagan Empires had ruled the nations. Most Jewish sources imagine a restoration of Israel and either a destruction of the nations or a gathering of the nations to obedience to the One True God. Jesus stands firmly in this tradition. His association of his own person and ministry with the "coming of the kingdom" indicates that he perceives that God's great intervention in history has arrived and that he is the agent of that intervention. However, in the Parable of the Mustard Seed, Jesus seems to indicate that his own view on how the kingdom of God arrives differs from the Jewish traditions of his time. It is commonly believed that this multiple-attested parable suggests that the growth of the kingdom of God is characterized by a gradual process rather than an event, and that it starts small like a seed and gradually grows into a large firmly rooted tree. His suffering and death, however, seem to cast doubt upon this (how could God's appointed king be killed?) but his resurrection affirms his claim with the ultimate proof of only God having resurrection power over death. The claim includes his exaltation to the right hand of God and establishes him as "king". Jesus' predictions of his return make it clear that God's kingdom is not yet fully realized according to inaugurated eschatology but in the meantime the good news that forgiveness of sins is available through his name is to be proclaimed to the nations. Thus the mission of the Church begins and fills the time between the initial coming of the Kingdom, and its ultimate consummation with the Final Judgment.

George Eldon Ladd (July 31, 1911 – October 5, 1982) was a Baptist minister and professor of New Testament theology and exegesis at Fuller Theological Seminary in Pasadena, California, known in Christian eschatology for his promotion of inaugurated eschatology and "futuristic post-tribulationism."

Realized eschatology is a Christian eschatological theory popularised by J.A.T. Robinson, Joachim Jeremias, Ethelbert Stauffer (1902–1979), and C. H. Dodd (1884–1973) that holds that the eschatological passages in the New Testament do not refer to the future, but instead refer to the ministry of Jesus and his lasting legacy. Eschatology is therefore not the end of the world but its rebirth instituted by Jesus and continued by his disciples, a historical (rather than transhistorical) phenomenon. Those holding this view generally dismiss eschatology theories, believing them to be irrelevant; they hold that what Jesus said and did, and told his disciples to do likewise, are of greater significance than any messianic expectations. Realized eschatology is contrasted with consistent eschatology. The two concepts have been combined in inaugurated eschatology.
