Council of TrentThe Council of Trent (Concilium Tridentinum), held between 1545 and 1563 in Trent (or Trento), now in northern Italy, was the 19th ecumenical council of the Catholic Church. Prompted by the Protestant Reformation at the time, it has been described as the embodiment of the Counter-Reformation. The Council issued condemnations of what it defined to be heresies committed by proponents of Protestantism, and also issued key statements and clarifications of the Church's doctrine and teachings, including scripture, the biblical canon, sacred tradition, original sin, justification, salvation, the sacraments, the Mass, and the veneration of saints.
TransubstantiationTransubstantiation (Latin: transubstantiatio; Greek: μετουσίωσις metousiosis) is, according to the teaching of the Catholic Church, "the change of the whole substance of bread into the substance of the Body of Christ and of the whole substance of wine into the substance of the Blood of Christ". This change is brought about in the eucharistic prayer through the efficacy of the word of Christ and by the action of the Holy Spirit. However, "the outward characteristics of bread and wine, that is the 'eucharistic species', remain unaltered".
Blood of ChristBlood of Christ, also known as the Most Precious Blood, in Christian theology refers to the physical blood actually shed by Jesus Christ primarily on the Cross, and the salvation which Christianity teaches was accomplished thereby, or the sacramental blood (wine) present in the Eucharist or Lord's Supper, which some Christian denominations believe to be the same blood of Christ shed on the Cross.
EcclesiologyIn Christian theology, ecclesiology is the study of the Church, the origins of Christianity, its relationship to Jesus, its role in salvation, its polity, its discipline, its eschatology, and its leadership. In its early history, one of the Church's primary ecclesiological issues had to do with the status of Gentile members in what had become the New Testament fulfilment of the essentially Jewish Old Testament church.
Church invisibleThe church invisible, invisible church, mystical church or church mystical, is a Christian theological concept of an "invisible" Christian Church of the elect who are known only to God, in contrast to the "visible church"—that is, the institutional body on earth which preaches the gospel and administers the sacraments. Every member of the invisible church is "saved", while the visible church contains all individuals who are saved though also having some who are "unsaved".
Catechism of the Catholic ChurchThe Catechism of the Catholic Church (Catechismus Catholicae Ecclesiae; commonly called the Catechism or the CCC) is a reference work that summarizes the Catholic Church's doctrine. It was promulgated by Pope John Paul II in 1992 as a reference for the development of local catechisms, directed primarily to those (in the Church) responsible for catechesis and offered as "useful reading for all other Christian faithful". It has been translated into and published in more than twenty languages worldwide.
Reformed worshipReformed worship is religious devotion to God as conducted by Reformed or Calvinistic Christians, including Presbyterians. Despite considerable local and national variation, public worship in most Reformed and Presbyterian churches is governed by the Regulative principle of worship. Huldrych Zwingli, who began his reforming work in Zurich in 1518, introduced many radical changes to worship. His Sunday service, instituted in 1519, was apparently derived from a liturgy called Prone, a late Medieval service which was sometimes held before, during, or after mass.
Holy LeavenHoly Leaven, also known as Malka (ܡܲܠܟܵܐ, ˈmalkaː), is a powder added to the sacramental bread used in the Eucharist of both the Ancient Church of the East and the Assyrian Church of the East and historically in the Church of the East. Both churches hold the Holy Leaven to be one of their seven sacraments. The Syro-Malabar Church in India, which was historically a part of the Church of the East, also uses Holy Leaven to prepare sacramental bread in several churches whereas unleavened bread is also in use.
DeaconessThe ministry of a deaconess is a usually non-ordained ministry for women in some Protestant, Oriental Orthodox, and Eastern Orthodox churches to provide pastoral care, especially for other women, and which may carry a limited liturgical role. The word comes from the Greek diakonos (διάκονος), for "deacon", which means a servant or helper and occurs frequently in the Christian New Testament of the Bible. Deaconesses trace their roots from the time of Jesus Christ through to the 13th century in the West.
Christian burialA Christian burial is the burial of a deceased person with specifically Christian rites; typically, in consecrated ground. Until recent times Christians generally objected to cremation because it interfered with the concept of the resurrection of a corpse, and practiced inhumation almost exclusively. Today this opposition has all but vanished among Protestants and Catholics alike, and this is rapidly becoming more common, although Eastern Orthodox Churches still mostly forbid cremation.
