Immersion baptism in the context of "Baptize"

Baptism (from Koine Greek: βάπτισμα, romanized: váptisma, lit. 'immersion, dipping in water') is a Christian rite of initiation almost invariably with the use of water. It may be performed by sprinkling or pouring water on the head, or immersing in water (partially or completely), traditionally three times for each person of the Trinity. It is also called christening, although this is typically reserved for the baptism of infants. Baptism is regarded as a sacrament in most churches and an ordinance in others, with the synoptic gospels recounting that John the Baptist baptized Jesus.

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. 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.

Baptists are a Protestant tradition of Christianity distinguished by baptizing only believers (believer's baptism) and doing so by total immersion. Modern Baptist churches generally subscribe to the doctrines of soul competency (the responsibility and accountability of every person before God), sola fide (justification by faith alone), sola scriptura (the Bible as the sole infallible authority) and congregationalist ecclesiastical polity. Baptists generally recognize at least two sacraments or ordinances: Baptism and the Lord's Supper.

Diverse from their beginnings, those identifying as Baptists today may differ widely from one another in what they believe, how they worship, their attitudes toward other Christians, and their understanding of what is important in Christian discipleship. Baptist missionaries have spread various Baptist churches to every continent. The largest Baptist communion of churches is the Baptist World Alliance, and there are many different groupings of Baptist churches and Baptist congregations.

Aspersion (la. aspergere/aspersio), in a religious context, is the act of sprinkling with water, especially holy water. Aspersion is a method used in baptism as an alternative to immersion or affusion. The word is formed of the Latin aspergere, 'to sprinkle', of ad, 'to', and spargo, 'I scatter' (Ezekiel 36:25–26, 1 Corinthians 10:2, cf. Psalm 77:16-20).

In addition, aspersion is performed as part of certain rites to remind people of their baptism, such as the renewal of baptismal vows performed by the Catholic Church and Lutheran Church at Easter.

Affusion 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 or 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. Affusion and aspersion tend to be practiced by Christian denominations that also practice infant baptism. This may be due to the practical difficulties and dangers of drowning and hypothermia associated with totally immersing an infant in cold water. However, most Eastern Christians (e.g. Eastern Orthodox) and some Catholics practice infant immersion. Amish, Old Order Mennonites, and Conservative Mennonites still practice baptism by pouring.

Believer's baptism (also called credobaptism, from the Latin word credo meaning "I believe") is the practice of baptizing those who are able to make a conscious profession of faith, as contrasted to the practice of baptizing infants. Credobaptists believe that infants incapable of consciously believing should not be baptized.

The mode of believer's baptism depends on the Christian denomination, and is done either by pouring (the normative method in Mennonite, Amish, and Hutterite churches) or by immersion (the normative method practiced by Schwarzenau Brethren, River Brethren, Baptists, and the Churches of Christ, among others). Among those denominations that practice immersion, the way that it is practiced depends on the Church; the Schwarzenau Brethren and the River Brethren for example teach "trine immersion, that is, dipping three times forward in the name of the Father, the Son, and the Holy Spirit."
