Immersion baptism (also known as baptism by immersion or baptism by submersion) is a method of baptism that is distinguished from baptism by affusion (pouring) and by aspersion (sprinkling), sometimes without specifying whether the immersion is total or partial,[1][2][3][4][5] but very commonly with the indication that the person baptized is immersed in water completely.[6][7][8][9] The term is also, though less commonly, applied exclusively to modes of baptism that involve only partial immersion (see Terminology, below).

^"In Christianity, baptism—either by plunging in water or by sprinkling with it—represents the first act of incorporation 'into Christ' and into the fellowship of the church." – Fahlbusch & Bromiley (eds.), The Encyclopedia of Christianity, volume 1, (Eerdmans, 1999–2003), p. 183
^"The word baptism is a transliteration of the Greek word baptizo which means to plunge, to dip, or to immerse… In New Testament times baptism was by a single immersion, with triple immersions appearing only later; occasionally, in cases of sickness or lack of water, affusion was practiced" – Myers, A.C., The Eerdmans Bible Dictionary (Eerdmans 1987), p. 123
^"Some form of immersion is envisaged, although affusion is allowed if running or standing water is lacking: 'If you do not have either, pour water three times on the head'." – Martin, R.P., & Davids, P.H. (2000). Dictionary of the later New Testament and its developments (electronic ed.).
^"Immersion, Baptism by (BAP-tih-zuhm bai ih-MER-shuhn): A method of baptizing whereby the whole person is submerged in water three times while the Trinitarian formula is pronounced. In the Rite of Baptism, immersion is indicated as the first way to baptize. For immersion, the candidate steps down or into a pool of water at waist height." – Stravinskas, Catholic Dictionary (Our Sunday Visitor 1993, 2002), p. 402
^""While much debate has focused on the varying interpretations of the forms of baptism, each form (immersion, sprinkling, or pouring) is clearly associated with the concept of cleansing and identification, which are the two integral parts of Spirit baptism. Immersion, however, depicts more clearly the symbolic aspect of baptism since its three steps—immersion (going into the water), submersion (going under the water), and emersion (coming out of the water)—more closely parallel the concept of entering into the death of Christ, experiencing the forgiveness of sins, and rising to walk in the newness of Christ's resurrected life (Rom 6:4)." – Douglas, & Tenney (eds.), New International Bible Dictionary (Zondervan 1987), p. 124
^"According to the rules of by far the largest portion of the Christian Church the water may be used in any one of three ways: immersion, where the recipient enters bodily into the water, and where, during the action, the head is plunged either once or three times beneath the surface; affusion, where water is poured upon the head of the recipient who stands either in water or on dry ground; and aspersion, where water is sprinkled on the head or on the face. 1. Immersion It has frequently been argued that the word baptízein invariably means 'to dip' or 'immerse' and that therefore Christian baptism must have been performed originally by immersion only, and that the other two forms, infusion and aspersion, are invalid – that there can be no real baptism unless the method of immersion be used. But the word that invariably means 'to dip' is not baptízein but báptein; baptízein has a wider signification; and its use to denote the Jewish ceremonial of pouring water on the hands (Lk. 11:38; Mk. 7:4), as has already been said, shows that it is impossible to conclude from the word itself that immersion is the only valid method of performing the rite… When immersion was used the head of the recipient was plunged thrice beneath the surface at the mention of each name of the trinity; when the mode was by affusion the same reference to the trinity was kept by pouring water thrice upon the head. The two usages that were recognized and prescribed by the beginning of the 2nd cent. may have been in use throughout the apostolic period, although definitive information is lacking." T.M.

^'One of their strongest arguments revolves around the Greek word for baptism in the New Testament. Its predominant meaning is "to immerse" or "to dip," implying that the candidate was plunged beneath the water.', Youngblood, R.F., Bruce, F.F., Harrison, R.K., & Thomas Nelson. (1995).
