Nostra aetateNostra aetate (from Latin: "In our time"), or the Declaration on the Relation of the Church with Non-Christian Religions, is an official declaration of the Second Vatican Council. Passed by a vote of 2,221 to 88 of the assembled bishops, this declaration was promulgated on 28 October 1965 by Pope Paul VI. Its name comes from its incipit. It is the shortest of the 16 final documents of the Council and "the first in Catholic history to focus on the relationship that Catholics have with Jews.
FilioqueFilioque (ˌfɪliˈoʊkwi,_-kweɪ ; filiˈokwe), a Latin term meaning "and from the Son," was added to the original Niceno-Constantinopolitan Creed (commonly known as the Nicene Creed), and has been the subject of great controversy between Eastern and Western Christianity. The term refers to the Son, Jesus Christ, with the Father, as the one shared origin of the Holy Spirit. It is not in the original text of the Creed, attributed to the First Council of Constantinople (381), which says that the Holy Spirit proceeds "from the Father", without additions of any kind, such as "and the Son" or "alone".
Pope Paul VIPope Paul VI (Paulus VI; Paolo VI; born Giovanni Battista Enrico Antonio Maria Montini, dʒoˈvanni batˈtista enˈriːko anˈtɔːnjo maˈriːa monˈtiːni; 26 September 1897 - 6 August 1978) was head of the Catholic Church and sovereign of the Vatican City State from 21 June 1963 to his death in August 1978. Succeeding John XXIII, he continued the Second Vatican Council, which he closed in 1965, implementing its numerous reforms. He fostered improved ecumenical relations with Eastern Orthodox and Protestant churches, which resulted in many historic meetings and agreements.
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.
