LutheranismLutheranism is a major branch of Protestantism, identifying primarily with the theology of Martin Luther, the 16th-century German monk and reformer whose efforts to reform the theology and practices of the Catholic Church launched the Protestant Reformation. The split between the Lutherans and the Roman Catholics was made public and clear with the 1521 Edict of Worms.
ProtestantismProtestantism is a branch of Christianity that follows the theological tenets of the Protestant Reformation, a movement that began in the 16th century with the goal of reforming the Catholic Church from perceived errors, abuses, and discrepancies. Protestantism emphasizes the Christian believer's justification by God in faith alone (sola fide) rather than by a combination of faith with good works as in Catholicism; the teaching that salvation comes by divine grace or "unmerited favor" only (sola gratia); the priesthood of all believers in the Church; and the sola scriptura ("scripture alone") that posits the Bible as the sole infallible source of authority for Christian faith and practice.
SacramentA sacrament is a Christian rite that is recognized as being particularly important and significant. There are various views on the existence, number and meaning of such rites. Many Christians consider the sacraments to be a visible symbol of the reality of God, as well as a channel for God's grace. Many denominations, including the Catholic, Lutheran, Anglican, Methodist, and Reformed, hold to the definition of sacrament formulated by Augustine of Hippo: an outward sign of an inward grace, that has been instituted by Jesus Christ.
Real presence of Christ in the EucharistThe real presence of Christ in the Eucharist is the Christian doctrine that Jesus Christ is present in the Eucharist, not merely symbolically or metaphorically, but in a true, real and substantial way. There are a number of Christian denominations that teach that Christ is truly present in the Eucharist, including Catholicism, Eastern Orthodoxy, Oriental Orthodoxy, the Church of the East, the Moravian Church, Lutheranism, Anglicanism, Methodism, Irvingism and Reformed Christianity.
Sacramental unionSacramental union (Latin: unio sacramentalis; Martin Luther's German: Sacramentliche Einigkeit; German: sakramentalische Vereinigung) is the Lutheran theological doctrine of the Real Presence of the body and blood of Christ in the Christian Eucharist (see Eucharist in Lutheranism). The sacramental union is distinguished from the other "unions" in theology like the "personal union" of the two natures in Jesus Christ, the "mystical union" of Christ and his Church, and the "natural union" in the human person of body and soul.
Divine LiturgyDivine Liturgy (Theia Leitourgia) or Holy Liturgy is the Eucharistic service of the Byzantine Rite, a liturgical rite developed from the Antiochene Rite of Christian liturgy which is that of the Ecumenical Patriarchate of Constantinople. As such, it is used in the Eastern Orthodox, the Greek Catholic Churches, and the Ukrainian Lutheran Church. Although the same term is sometimes applied in English to the Eucharistic service of Armenian Christians, both of the Armenian Apostolic Church and of the Armenian Catholic Church, they use in their own language a term meaning "holy offering" or "holy sacrifice".
Counter-ReformationThe Counter-Reformation (Contrareformatio), also called the Catholic Reformation (Reformatio Catholica) or the Catholic Revival, was the period of Catholic resurgence that was initiated in response to the Protestant Reformation at the time. It began with the Council of Trent (1545–1563) and largely ended with the conclusion of the European wars of religion in 1648. Initiated to address the effects of the Protestant Reformation, the Counter-Reformation was a comprehensive effort composed of apologetic and polemical documents and ecclesiastical configuration as decreed by the Council of Trent.
