EcumenismEcumenism (ɪˈkjuːməˌnɪzəm ; alternatively spelled oecumenism) - also called interdenominationalism, transdenominationalism, or ecumenicalism - is the concept and principle that Christians who belong to different Christian denominations should work together to develop closer relationships among their churches and promote Christian unity. The adjective ecumenical is thus applied to any interdenominational initiative that encourages greater cooperation and union among Christian denominations and churches.
TheotokosTheotokos (Greek: Θεοτόκος) is a title of Mary, mother of Jesus, used especially in Eastern Christianity. The usual Latin translations are Dei Genitrix or Deipara (approximately "parent (fem.) of God"). Familiar English translations are "Mother of God" or "God-bearer" – but these both have different literal equivalents in Greek, Μήτηρ Θεοῦ and Θεοφόρος ("Who gave birth to one who was God", "Whose child was God", respectively).
Ecumenical councilAn ecumenical council, also called general council, is a meeting of bishops and other church authorities to consider and rule on questions of Christian doctrine, administration, discipline, and other matters in which those entitled to vote are convoked from the whole world (oikoumene) and which secures the approbation of the whole Church.
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.
Mary, mother of JesusMary was a first-century Judean woman of Nazareth, the wife of Joseph and the mother of Jesus. She is a central figure of Christianity, venerated under various titles such as virgin or queen, many of them mentioned in the Litany of Loreto. The Eastern and Oriental Orthodox, Church of the East, Catholic, Anglican, and Lutheran churches believe that Mary, as mother of Jesus, is the Mother of God. Other Protestant views on Mary vary, with some holding her to have considerably lesser status.
JesusJesus (6 to 4 BC - AD 30 or 33), also referred to as Jesus Christ, Jesus of Nazareth, and several other names and titles, was a first-century Jewish preacher and religious leader. He is the central figure of Christianity, the world's largest religion. Most Christians believe Jesus to be the incarnation of God the Son and the awaited messiah, the Christ that is prophesied in the Hebrew Bible. Virtually all modern scholars of antiquity agree that Jesus existed historically.
