Baptism is a Christian sacrament of initiation almost invariably with the use of water. It may be performed by sprinkling or pouring water on the head, or by immersing in water either partially or completely, traditionally three times, once for each person of the Trinity. The synoptic gospels recount that John the Baptist baptised Jesus. Baptism is considered a sacrament in most churches, and as an ordinance in others. Baptism according to the Trinitarian formula, which is done in most mainstream Christian denominations, is seen as being a basis for Christian ecumenism, the concept of unity amongst Christians. Baptism is also called christening, although some reserve the word "christening" for the baptism of infants. In certain Christian denominations, such as the Catholic Churches, Eastern Orthodox Churches, Oriental Orthodox Churches, Assyrian Church of the East, and Lutheran Churches, baptism is the door to church membership, with candidates taking baptismal vows. It has also given its name to the Baptist churches and denominations.
To be born again, or to experience the new birth, is a phrase, particularly in evangelicalism, that refers to a "spiritual rebirth", or a regeneration of the human spirit. In contrast to one's physical birth, being "born again" is distinctly and separately caused by the operation of the Holy Spirit, and it occurs when one surrenders their life to Christ. It is a core doctrine of the denominations of the Anabaptist, Moravian, Methodist, Baptist, Plymouth Brethren and Pentecostal Churches along with all other evangelical Christian denominations. All of these Churches strongly believe Jesus's words in the Gospels: "You must be born again before you can see, or enter, the Kingdom of Heaven". Their doctrines also mandate that to be both "born again" and "saved", one must have a personal and intimate relationship with Jesus Christ.
Infant baptism is the practice of baptizing infants or young children. Infant baptism is also called christening by some faith traditions.
Oneness Pentecostalism is a nontrinitarian religious movement within the Protestant Christian family of churches known as Pentecostalism. It derives its name from its teaching on the Godhead, a form of Modalistic Monarchianism commonly referred to as the Oneness doctrine. The doctrine states that there is one God―a singular divine spirit with no distinction of persons―who manifests himself in many ways, including as Father, Son, and Holy Spirit. This stands in sharp contrast to the mainstream doctrine of three distinct, eternal persons posited by Trinitarian theology.
The five solae of the Protestant Reformation are a foundational set of Christian theological principles held by theologians and clergy to be central to the doctrines of justification and salvation as taught by the Calvinism and Lutheranism branches of Protestantism, as well as in some branches of Pentecostalism. Each sola represents a key belief in these Protestant traditions that is distinct from the theological doctrine of the Catholic Church, although they were not assembled as a theological unit until the 20th century. The Reformers are known to have only clearly stated two of the five solae. Even today there are differences as to what constitutes the solae, how many there are, and how to interpret them to reflect the Reformers' beliefs.
In Christianity, salvation is the saving of human beings from sin and its consequences—which include death and separation from God—by Christ's death and resurrection, and the justification entailed by this salvation.
In Christian theology, justification is the event or process by which sinners are made or declared to be righteous in the sight of God.
The means of grace in Christian theology are those things through which God gives grace. Just what this grace entails is interpreted in various ways: generally speaking, some see it as God blessing humankind so as to sustain and empower the Christian life; others see it as forgiveness, life, and salvation.
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 Protestant Christianity, the relationship between Law and Gospel—God's Law and the Gospel of Jesus Christ—is a major topic in Lutheran and Reformed theology. In these religious traditions, the distinction between the doctrines of Law, which demands obedience to God's ethical will, and Gospel, which promises the forgiveness of sins in light of the person and work of Jesus Christ, is critical. Ministers use it as a hermeneutical principle of biblical interpretation and as a guiding principle in homiletics and pastoral care. It involves the supersession of the Old Covenant by the New Covenant and Christian theology.
The Sinner's prayer is an evangelical Baptist term referring to any prayer of repentance, prayed by individuals who feel sin in their lives and have the desire to form or renew a personal relationship. This prayer is not mandatory but, for some, functions as a way to communicate with and understand their relationship with God through Jesus Christ. It is a popular prayer in evangelical circles. It is not intended as liturgical like a creed or a confiteor said or chanted within the Catholic Mass, but rather, is intended to be an act of initial conversion to Christianity. It is roughly analogous to the Catholic Act of Contrition, though the theology behind each is markedly different, due to the intrinsically different views of salvation between Catholicism and Protestantism. While some Christians see reciting the Sinner's prayer as the moment defining one's salvation, others see it as a beginning step of one's lifelong faith journey.
Regeneration, while sometimes perceived to be a step in the ordo salutis, is generally understood in Christian theology to be the objective work of God in a believer's life. Spiritually, it means that God brings a person to new life from a previous state of separation from God and subjection to the decay of death. Thus, in Lutheran and Roman Catholic theology, it generally means that which takes place during baptism. In Calvinism and Arminian theology, baptism is recognized as an outward sign of an inward reality which is to follow regeneration as a sign of obedience to the New Testament; as such, the Methodist Churches teach that regeneration occurs during the new birth.
Baptismal regeneration is the name given to doctrines held by the Catholic, Eastern Orthodox, Oriental Orthodox, Lutheran, Anglican churches, and other Protestant denominations which maintain that salvation is intimately linked to the act of baptism, without necessarily holding that salvation is impossible apart from it. Etymologically, the term means "being born again" "through baptism" (baptismal). Etymology concerns the origins and root meanings of words, but these "continually change their meaning, ... sometimes moving out of any recognisable contact with their origin ... It is nowadays generally agreed that current usage determines meaning." While for Reformed theologian Louis Berkhof, "regeneration" and "new birth" are synonymous, Herbert Lockyer treats the two terms as different in meaning in one publication, but in another states that baptism signifies regeneration.
The Association of Independent Methodists (AIM) is a fellowship of independent Methodist congregations that are aligned with the holiness movement. The Association is based in the United States, being founded in 1965 by churches who left the mainline Methodist Church because of disagreements on church government and doctrinal matters. As of 2024, the denomination has 100 churches in 11 U.S. states, concentrated mostly in the Southern United States.
In Lutheranism, the Eucharist refers to the liturgical commemoration of the Last Supper. Lutherans believe in the real presence of Christ in the Eucharist, affirming the doctrine of sacramental union, "in which the body and blood of Christ are truly and substantially present, offered, and received with the bread and wine."
Lutheranism is a major branch of Protestantism that identifies 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 Reformation in 1517. Lutheranism subsequently became the state religion of many parts of Northern Europe.
Christian theology is the theology – the systematic study of the divine and religion – of Christian belief and practice. It concentrates primarily upon the texts of the Old Testament and of the New Testament, as well as on Christian tradition. Christian theologians use biblical exegesis, rational analysis and argument. Theologians may undertake the study of Christian theology for a variety of reasons, such as in order to:
Sola gratia, meaning by grace alone, is one of the five solae and consists in the belief that salvation comes by divine grace or "unmerited favor" only, not as something earned or deserved by the sinner. It is a Christian theological doctrine held by some Protestant Christian denominations, in particular the Lutheran and Reformed traditions of Protestantism, propounded to summarise the Protestant Reformers' basic soteriology during the Reformation. In addition, salvation by grace is taught by the Catholic Church: "By the grace of God, we are saved through our faith; this faith entails by its very nature, good works, always enabled by prior grace, without which this faith is dead."
Criticism of Protestantism covers critiques and questions raised about Protestantism, the Christian denominations which arose out of the Protestant Reformation. While critics may praise some aspects of Protestantism which are not unique to the various forms of Protestantism, Protestantism is faced with criticism mainly from the Catholic Church and the Eastern Orthodox Church, although Protestant denominations have also engaged in self-critique and criticized one another. According to both the Catholic Church and Eastern Orthodoxy, many major, foundational Protestant doctrines have been officially declared heretical.
Evangelical theology is the teaching and doctrine that relates to spiritual matters in evangelical Christianity and a Christian theology. The main points concern the place of the Bible, the Trinity, worship, Salvation, sanctification, charity, evangelism and the end of time.
