Early ChristianityEarly Christianity, or Paleochristianity, describes the historical era of the Christian religion up to the First Council of Nicaea in 325. Christianity spread from the Levant, across the Roman Empire, and beyond. Originally, this progression was closely connected to already established Jewish centers in the Holy Land and the Jewish diaspora. The first followers of Christianity were Jews who had converted to the faith, i.e. Jewish Christians. Early Christianity contains the Apostolic age and is followed by, and substantially overlaps with, the Patristic era.
ProtestantismProtestantism is a branch of Christianity that follows the theological tenets of the Protestant Reformation, a movement that began in the 16th century with the goal of reforming the Catholic Church from perceived errors, abuses, and discrepancies. Protestantism emphasizes the Christian believer's justification by God in faith alone (sola fide) rather than by a combination of faith with good works as in Catholicism; the teaching that salvation comes by divine grace or "unmerited favor" only (sola gratia); the priesthood of all believers in the Church; and the sola scriptura ("scripture alone") that posits the Bible as the sole infallible source of authority for Christian faith and practice.
Christianity in the ante-Nicene periodChristianity 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 second and third centuries saw a sharp divorce of Christianity from its early roots. There was an explicit rejection of then-modern Judaism and Jewish culture by the end of the second century, with a growing body of adversus Judaeos literature.
Christian crossThe Christian cross, seen as a representation of the crucifixion of Jesus on a large wooden cross, is a renowned symbol of Christianity. It is related to the crucifix (a cross that includes a corpus, usually a three-dimensional with representation of Jesus' body) and to the more general family of cross symbols, the term cross itself being detached from the original specifically Christian meaning in modern English (as in many other western languages).
Apostles' CreedThe Apostles' Creed (Latin: Symbolum Apostolorum or Symbolum Apostolicum), sometimes titled the Apostolic Creed or the Symbol of the Apostles, is a Christian creed or "symbol of faith". The creed most likely originated in 5th-century Gaul as a development of the Old Roman Symbol: the old Latin creed of the 4th century. It has been used in the Latin liturgical rites since the 8th century and, by extension, in the various modern branches of Western Christianity, including the modern liturgy and catechesis of the Catholic Church, Lutheranism, Anglicanism, Presbyterianism, Moravianism, Methodism, and Congregational churches.
Sacred mysteriesSacred 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. A mystagogue or hierophant is a holder and teacher of secret knowledge in the former sense above, while mysticism may be defined as an area of philosophical or religious thought focusing on mysteries in the latter sense.
Christianity in the 4th centuryChristianity in the 4th century was dominated in its early stage by Constantine the Great and the First Council of Nicaea of 325, which was the beginning of the period of the First seven Ecumenical Councils (325–787), and in its late stage by the Edict of Thessalonica of 380, which made Nicene Christianity the state church of the Roman Empire.

AffusionAffusion (la. affusio) is a method of baptism where water is poured on the head of the person being baptized. The word "affusion" comes from the Latin affusio, meaning "to pour on". Affusion is one of four methods of baptism used by Christians, which also include total submersion baptism, partial immersion baptism, and aspersion or sprinkling. Christian denominations which baptize by affusion do not deny the legitimacy of baptizing by submersion or immersion; rather, they consider that affusion is a sufficient, if not necessarily preferable, method of baptism.
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.
Roman MissalThe Roman Missal (Missale Romanum) is the title of several missals used in the celebration of the Roman Rite. Along with other liturgical books of the Roman Rite, the Roman Missal contains the texts and rubrics for the celebration of the most common liturgy and Mass of the Catholic Church. Before the high Middle Ages, several books were used at Mass: a Sacramentary with the prayers, one or more books for the Scriptural readings, and one or more books for the antiphons and other chants.
