Cyril of Jerusalem was a theologian of the Early Church. About the end of AD 350, he succeeded Maximus as Bishop of Jerusalem, but was exiled on more than one occasion due to the enmity of Acacius of Caesarea, and the policies of various emperors. Cyril left important writings documenting the instruction of catechumens and the order of the Liturgy in his day.
The Eucharist, also known as Holy Communion, the Blessed Sacrament and the Lord's Supper, is a Christian rite that is considered a sacrament in most churches, and as an ordinance in others. Christians believe that the rite was instituted by Jesus at the Last Supper, the night before his crucifixion, giving his disciples bread and wine. Passages in the New Testament state that he commanded them to "do this in memory of me" while referring to the bread as "my body" and the cup of wine as "the blood of my covenant, which is poured out for many". According to the Synoptic Gospels this was at a Passover meal.
Tertullian was a prolific early Christian author from Carthage in the Roman province of Africa. He was the first Christian author to produce an extensive corpus of Latin Christian literature and was an early Christian apologist and a polemicist against heresy, including contemporary Christian Gnosticism. Tertullian has been called "the father of Latin Christianity", as well as "the founder of Western theology".
Mystery religions, mystery cults, sacred mysteries or simply mysteries, were religious schools of the Greco-Roman world for which participation was reserved to initiates (mystai). The main characteristic of these religious schools was the secrecy associated with the particulars of the initiation and the ritual practice, which may not be revealed to outsiders. The most famous mysteries of Greco-Roman antiquity were the Eleusinian Mysteries, which predated the Greek Dark Ages. The mystery schools flourished in Late Antiquity; Emperor Julian, of the mid-4th century, is believed by some scholars to have been associated with various mystery cults—most notably the mithraists. Due to the secret nature of the schools, and because the mystery religions of Late Antiquity were persecuted by the Christian Roman Empire from the 4th century, the details of these religious practices are derived from descriptions, imagery and cross-cultural studies. Much information on the mysteries comes from Marcus Terentius Varro.
The Great Apostasy is a concept within Christianity to describe a perception that mainstream Christian Churches have fallen away from the original faith founded by Jesus and promulgated through his Twelve Apostles.
The 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.
Sacred mysteries are the areas of supernatural phenomena associated with a divinity or a religious belief and praxis. Sacred mysteries may be either:
- Religious beliefs, rituals or practices which are kept secret from the uninitiated.
- Beliefs of the religion which are public knowledge but cannot be easily explained by normal rational or scientific means.
Esoteric Christianity is a mystical approach to Christianity which features "secret traditions" that require an initiation to learn or understand. The term esoteric was coined in the 17th century and derives from the Greek ἐσωτερικός.
The sacraments of initiation are the three sacraments of Baptism, Confirmation, and Eucharist in Nicene Christianity. As such, they are distinguished from the sacraments of healing and from the sacraments of service.
Eucharistic theology is a branch of Christian theology which treats doctrines concerning the Holy Eucharist, also commonly known as the Lord's Supper and Holy Communion. It exists exclusively in Christianity, as others generally do not contain a Eucharistic ceremony.
In the history of Christianity, the African Rite refers to a now defunct Christian, Latin liturgical rite, and is considered a development or possibly a local use of the primitive Roman Rite. Centered around the Archdiocese of Carthage in the Early African church, it used the Latin language.
Catechesis is basic Christian religious education of children and adults, often from a catechism book. It started as education of converts to Christianity, but as the religion became institutionalized, catechesis was used for education of members who had been baptized as infants. As defined in the Catechism of the Catholic Church, paragraph 5 :
Catechesis is an education in the faith of children, young people and adults which includes especially the teaching of Christian doctrine imparted, generally speaking, in an organic and systematic way, with a view to initiating the hearers into the fullness of Christian life.
During the Liturgy of the Eucharist, the second part of the Mass, the elements of bread and wine are considered to have been changed into the veritable Body and Blood of Jesus Christ. The manner in which this occurs is referred to by the term transubstantiation, a theory of St. Thomas Aquinas, in the Roman Catholic Church. Members of the Orthodox, Anglican, and Lutheran communions also believe that Jesus Christ is really and truly present in the bread and wine, but they believe that the way in which this occurs must forever remain a sacred mystery. In many Christian churches, some portion of the consecrated elements is set aside and reserved after the reception of Communion and referred to as the reserved sacrament. The reserved sacrament is usually stored in a tabernacle, a locked cabinet made of precious materials and usually located on, above, or near the high altar. In Western Christianity usually only the Host, from Latin: hostia, meaning "victim", is reserved, except where wine might be kept for the sick who cannot consume a host.
The Antiochene or Antiochian Rite refers to the family of liturgies originally used by the patriarch of Antioch. It includes the Liturgy of St James in Greek and Syriac, as well as other West Syriac Anaphoras.
Against Celsus, preserved entirely in Greek, is a major apologetics work by the Church Father Origen of Alexandria, written in around 248 AD, countering the writings of Celsus, a pagan philosopher and controversialist who had written a scathing attack on Christianity in his treatise The TrueWord. Among a variety of other charges, Celsus had denounced many Christian doctrines as irrational and criticized Christians themselves as uneducated, deluded, unpatriotic, close-minded towards reason, and too accepting of sinners. He had accused Jesus of performing his miracles using black magic rather than actual divine powers and of plagiarizing his teachings from Plato. Celsus had warned that Christianity itself was drawing people away from traditional religion and claimed that its growth would lead to a collapse of traditional, conservative values.
Christianity in the ante-Nicene period was the time in Christian history up to the First Council of Nicaea. This article covers the period following the Apostolic Age of the first century, c. 100 AD, to Nicaea in 325 AD.
The True Word is a lost treatise in which the ancient Greek philosopher Celsus addressed many principal points of early Christianity and refuted or argued against their validity. In The True Word, Celsus attacked Christianity in three ways: by refuting its philosophical claims, by marking it as a phenomenon associated with the uneducated and lower class, and by cautioning his audience that it was a danger to the Roman Empire. Information concerning the work exists only in the extensive quotations from it in the Contra Celsum, written some seventy years later by the Christian Origen. These are believed to be accurate as far as they go, but may not give a fully comprehensive picture of the original work.
John the Baptist, who is considered a forerunner to Christianity, used baptism as the central sacrament of his messianic movement. Christians consider Jesus to have instituted the sacrament of baptism. The earliest Christian baptisms were by immersion. By the third and fourth centuries, baptism involved catechetical instruction as well as chrismation, exorcisms, laying on of hands, and recitation of a creed. In the West, affusion became the normal mode of baptism between the twelfth and fourteenth centuries, though immersion was still practiced into the sixteenth. In the sixteenth century, Martin Luther retained baptism as a sacrament, but Swiss reformer Huldrych Zwingli considered baptism and the Lord's supper to be symbolic. Anabaptists denied the validity of infant baptism, which was the normal practice when their movement started and practiced believer's baptism instead. Several groups related to Anabaptism, notably the Baptists and Dunkards, soon practiced baptism by immersion as following the Biblical example.
The Order of Christian Initiation of Adults (Latin: Ordo initiationis christianae adultorum), or OCIA, is a process developed by the Catholic Church for its catechumenate for prospective converts to the Catholic faith above the age of infant baptism. Candidates are gradually introduced to aspects of Catholic beliefs and practices. The basic process applies to adults and children who have reached catechetical age. In many English speaking countries, it is called Rite of Christian Initiation of Adults (RCIA). In the United States, the name was changed to the OCIA in 2021 to reflect greater fidelity to the original Latin, although this change has yet to be officially approved by the Dicastery for Divine Worship and the Discipline of the Sacraments.
The expression minor exorcism can be used in a technical sense or a general sense. The general sense indicates any exorcism which is not a solemn exorcism of a person believed to be possessed, including various forms of deliverance ministry. This article deals only with the technical sense which specifically refers to certain prayers used with persons preparing to become baptised members of the churches which makes use of such rites. These prayers request God's assistance so that the person to be baptised will be kept safe from the power of Satan or protected in a more general way from temptation.
