Catholic theologyCatholic theology is the understanding of Catholic doctrine or teachings, and results from the studies of theologians. It is based on canonical scripture, and sacred tradition, as interpreted authoritatively by the magisterium of the Catholic Church. This article serves as an introduction to various topics in Catholic theology, with links to where fuller coverage is found. Major teachings of the Catholic Church discussed in the early councils of the church are summarized in various creeds, especially the Nicene (Nicene-Constantinopolitan) Creed and the Apostles' Creed.
Sacrament of PenanceThe Sacrament of Penance (also commonly called the Sacrament of Reconciliation or Confession) is one of the seven sacraments of the Catholic Church (known in Eastern Christianity as sacred mysteries), in which the faithful are absolved from sins committed after baptism and reconciled with the Christian community. During reconciliation mortal sins must be confessed and venial sins may be confessed for devotional reasons. According to the dogma and unchanging practice of the church, only those ordained as priests may grant absolution.
LentLent (Quadragesima, 'Fortieth') is the solemn Christian religious observance in the liturgical year commemorating the 40 days Jesus Christ spent fasting in the desert and enduring temptation by Satan, according to the Gospels of Matthew, Mark and Luke, before beginning his public ministry. Lent is observed in the Anglican, Eastern Orthodox, Lutheran, Methodist, Moravian, Oriental Orthodox, Church of the East, United Protestant and Roman Catholic traditions of Christianity.
Pope Gregory IPope Gregory I (Gregorius I; 540 – 12 March 604), commonly known as Saint Gregory the Great, was the bishop of Rome from 3 September 590 to his death. He is known for instituting the first recorded large-scale mission from Rome, the Gregorian mission, to convert the then largely pagan Anglo-Saxons to Christianity. Gregory is also well known for his writings, which were more prolific than those of any of his predecessors as pope. The epithet Saint Gregory the Dialogist has been attached to him in Eastern Christianity because of his Dialogues.
Eucharistic theologyEucharistic theology is a branch of Christian theology which treats doctrines concerning the Holy Eucharist, also commonly known as the Lord's Supper. It exists exclusively in Christianity and related religions, as others generally do not contain a Eucharistic ceremony. In the Gospel accounts of Jesus' earthly ministry, a crowd of listeners challenges him regarding the rain of manna before he delivers the famous Bread of Life Discourse (John 6:22–59), and he describes himself as the "True Bread from Heaven".
Host desecrationHost desecration is a form of sacrilege in Christian denominations that follow the doctrine of the real presence of Christ in the Eucharist. It involves the mistreatment or malicious use of a consecrated host—the bread used in the Eucharistic service of the Divine Liturgy or Mass (also known by Protestants simply as Communion bread). It is forbidden by the Catholic, Oriental Orthodox, and Eastern Orthodox Churches, as well as in certain Protestant traditions (including Anglicanism, Lutheranism, and Methodism).
Priesthood in the Catholic ChurchThe priesthood is the office of the ministers of religion, who have been commissioned ("ordained") with the Holy orders of the Catholic Church. Technically, bishops are a priestly order as well; however, in layman's terms priest refers only to presbyters and pastors (parish priests). The church's doctrine also sometimes refers to all baptised (lay) members as the "common priesthood", which can be confused with the ministerial priesthood of the consecrated clergy.
PurgatoryPurgatory ( purgatorium, borrowed into English via Anglo-Norman and Old French) is, according to the belief of some Christian denominations and Islam, an intermediate state after physical death for expiatory purification. The process of purgatory is the final purification of the elect, which is entirely different from the punishment of the damned. Tradition, by reference to certain texts of scripture, sees the process as involving a cleansing fire. Some forms of Western Christianity, particularly within Protestantism, deny its existence.
Holy waterHoly water is water that has been blessed by a member of the clergy or a religious figure, or derived from a well or spring considered holy. The use for cleansing prior to a baptism and spiritual cleansing is common in several religions, from Christianity to Sikhism. The use of holy water as a sacramental for protection against evil is common among Lutherans, Anglicans, Roman Catholics, and Eastern Christians.
SanctusThe Sanctus (Sanctus, "Holy") is a hymn in Christian liturgy. It may also be called the epinikios hymnos (ἐπινίκιος ὕμνος, "Hymn of Victory") when referring to the Greek rendition and parts of it are sometimes called "Benedictus". Tersanctus (Latin: "Thrice Holy") is another, rarer name for the Sanctus. The same name is sometimes used for the Trisagion. In Western Christianity, the Sanctus forms part of the Ordinary and is sung (or said) as the final words of the Preface of the Eucharistic Prayer of remembrance, consecration, and praise.
