Sola scripturaSola scriptura (Latin for 'by scripture alone') is a Christian theological doctrine held by most Protestant Christian denominations, in particular the Lutheran and Reformed traditions, that posits the Bible as the sole infallible source of authority for Christian faith and practice. The Catholic Church considers it heterodox and generally the Orthodox churches consider it to be contrary to the phronema of the Church.
Liturgical yearThe liturgical year, also called the church year, Christian year or kalendar, consists of the cycle of liturgical seasons in Christian churches that determines when feast days, including celebrations of saints, are to be observed, and which portions of Scripture are to be read either in an annual cycle or in a cycle of several years. Distinct liturgical colours may be used in connection with different seasons of the liturgical year. The dates of the festivals vary somewhat among the different churches, although the sequence and logic is largely the same.
Infant baptismInfant baptism (or paedobaptism) is the practice of baptising infants or young children. Infant baptism is also called christening by some faith traditions. Most Christians belong to denominations that practice infant baptism. Branches of Christianity that practice infant baptism include Catholicism, Eastern Orthodoxy, and Oriental Orthodoxy. Among Protestants, several denominations practice infant baptism including Anglicans, Lutherans, Presbyterians, Congregationalists, Methodists, Nazarenes, Moravians, and United Protestants.
Apostolic successionApostolic succession is the method whereby the ministry of the Christian Church is considered by some Christian denominations to be derived from the apostles by a continuous succession, which has usually been associated with a claim that the succession is through a series of bishops. Those of the Anglican, Church of the East, Eastern Orthodox, Hussite, Moravian, Old Catholic, Oriental Orthodox, Catholic and Scandinavian Lutheran traditions maintain that "a bishop cannot have regular or valid orders unless he has been consecrated in this apostolic succession".
LutheranismLutheranism is a major branch of Protestantism, identifying primarily with the theology of Martin Luther, the 16th-century German monk and reformer whose efforts to reform the theology and practices of the Catholic Church launched the Protestant Reformation. The split between the Lutherans and the Roman Catholics was made public and clear with the 1521 Edict of Worms.
