Whether immersion in water is necessary for Baptism?
Objection 1: It seems that immersion in water is necessary for Baptism. Because it is written ( Eph. 4:5 ): "One faith, one baptism." But in many parts of the world the ordinary way of baptizing is by immersion. Therefore it seems that there can be no Baptism without immersion.
Objection 2: Further, the Apostle says ( Rom. 6:3 , 4 ): "All we who are baptized in Christ Jesus, are baptized in His death: for we are buried together with Him, by Baptism into death." But this is done by immersion: for Chrysostom says on Jn. 3:5 : "Unless a man be born again of water and the Holy Ghost," etc.: "When we dip our heads under the water as in a kind of tomb, our old man is buried, and being submerged, is hidden below, and thence he rises again renewed." Therefore it seems that immersion is essential to Baptism.
Objection 3: Further, if Baptism is valid without total immersion of the body, it would follow that it would be equally sufficient to pour water over any part of the body. But this seems unreasonable; since original sin, to remedy which is the principal purpose of Baptism, is not in only one part of the body. Therefore it seems that immersion is necessary for Baptism, and that mere sprinkling is not enough.
On the contrary, It is written ( Heb. 10:22 ): "Let us draw near with a true heart in fulness of faith, having our hearts sprinkled from an evil conscience, and our bodies washed with clean water."
I answer that, In the sacrament of Baptism water is put to the use of a washing of the body, whereby to signify the inward washing away of sins. Now washing may be done with water not only by immersion, but also by sprinkling or pouring. And, therefore, although it is safer to baptize by immersion, because this is the more ordinary fashion, yet Baptism can be conferred by sprinkling or also by pouring, according to Ezech. 36:25 : "I will pour upon you clean water," as also the Blessed Lawrence is related to have baptized. And this especially in cases of urgency: either because there is a great number to be baptized, as was clearly the case in Acts 2 and 4, where we read that on one day three thousand believed, and on another five thousand: or through there being but a small supply of water, or through feebleness of the minister, who cannot hold up the candidate for Baptism; or through feebleness of the candidate, whose life might be endangered by immersion. We must therefore conclude that immersion is not necessary for Baptism.
Reply to Objection 1: What is accidental to a thing does not diversify its essence. Now bodily washing with water is essential to Baptism: wherefore Baptism is called a "laver," according to Eph. 5:26 : "Cleansing it by the laver of water in the word of life." But that the washing be done this or that way, is accidental to Baptism. And consequently such diversity does not destroy the oneness of Baptism.
Reply to Objection 2: Christ's burial is more clearly represented by immersion: wherefore this manner of baptizing is more frequently in use and more commendable. Yet in the other ways of baptizing it is represented after a fashion, albeit not so clearly; for no matter how the washing is done, the body of a man, or some part thereof, is put under water, just as Christ's body was put under the earth.
Reply to Objection 3: The principal part of the body, especially in relation to the exterior members, is the head, wherein all the senses, both interior and exterior, flourish. And therefore, if the whole body cannot be covered with water, because of the scarcity of water, or because of some other reason, it is necessary to pour water over the head, in which the principle of animal life is made manifest.
And although original sin is transmitted through the members that serve for procreation, yet those members are not to be sprinkled in preference to the head, because by Baptism the transmission of original sin to the offspring by the act of procreation is not deleted, but the soul is freed from the stain and debt of sin which it has contracted. Consequently that part of the body should be washed in preference, in which the works of the soul are made manifest.
Nevertheless in the Old Law the remedy against original sin was affixed to the member of procreation; because He through Whom original sin was to be removed, was yet to be born of the seed of Abraham, whose faith was signified by circumcision according to Rom. 4:11.
Whether trine immersion is essential to Baptism?
Objection 1: It seems that trine immersion is essential to Baptism. For Augustine says in a sermon on the Symbol, addressed to the Neophytes: "Rightly were you dipped three times, since you were baptized in the name of the Trinity. Rightly were you dipped three times, because you were baptized in the name of Jesus Christ, Who on the third day rose again from the dead. For that thrice repeated immersion reproduces the burial of the Lord by which you were buried with Christ in Baptism." Now both seem to be essential to Baptism, namely, that in Baptism the Trinity of Persons should be signified, and that we should be conformed to Christ's burial. Therefore it seems that trine immersion is essential to Baptism.
Objection 2: Further, the sacraments derive their efficacy from Christ's mandate. But trine immersion was commanded by Christ: for Pope Pelagius II wrote to Bishop Gaudentius: "The Gospel precept given by our Lord God Himself, our Saviour Jesus Christ, admonishes us to confer the sacrament of Baptism to each one in the name of the Trinity and also with trine immersion." Therefore, just as it is essential to Baptism to call on the name of the Trinity, so is it essential to baptize by trine immersion.
Objection 3: Further, if trine immersion be not essential to Baptism, it follows that the sacrament of Baptism is conferred at the first immersion; so that if a second or third immersion be added, it seems that Baptism is conferred a second or third time. which is absurd. Therefore one immersion does not suffice for the sacrament of Baptism, and trine immersion is essential thereto.
On the contrary, Gregory wrote to the Bishop Leander: "It cannot be in any way reprehensible to baptize an infant with either a trine or a single immersion: since the Trinity can be represented in the three immersions, and the unity of the Godhead in one immersion."
I answer that As stated above (A[7], ad 1), washing with water is of itself required for Baptism, being essential to the sacrament: whereas the mode of washing is accidental to the sacrament. Consequently, as Gregory in the words above quoted explains, both single and trine immersion are lawful considered in themselves; since one immersion signifies the oneness of Christ's death and of the Godhead; while trine immersion signifies the three days of Christ's burial, and also the Trinity of Persons.
But for various reasons, according as the Church has ordained, one mode has been in practice, at one time, the other at another time. For since from the very earliest days of the Church some have had false notions concerning the Trinity, holding that Christ is a mere man, and that He is not called the "Son of God" or "God" except by reason of His merit, which was chiefly in His death; for this reason they did not baptize in the name of the Trinity, but in memory of Christ's death, and with one immersion. And this was condemned in the early Church. Wherefore in the Apostolic Canons (xlix) we read: "If any priest or bishop confer baptism not with the trine immersion in the one administration, but with one immersion, which baptism is said to be conferred by some in the death of the Lord, let him be deposed": for our Lord did not say, "Baptize ye in My death," but "In the name of the Father and of the Son, and of the Holy Ghost."
Later on, however, there arose the error of certain schismatics and heretics who rebaptized: as Augustine (Super. Joan., cf. De Haeres. lxix) relates of the Donatists. Wherefore, in detestation of their error, only one immersion was ordered to be made, by the (fourth) council of Toledo, in the acts of which we read: "In order to avoid the scandal of schism or the practice of heretical teaching let us hold to the single baptismal immersion."
But now that this motive has ceased, trine immersion is universally observed in Baptism: and consequently anyone baptizing otherwise would sin gravely, through not following the ritual of the Church. It would, however, be valid Baptism.
Reply to Objection 1: The Trinity acts as principal agent in Baptism. Now the likeness of the agent enters into the effect, in regard to the form and not in regard to the matter. Wherefore the Trinity is signified in Baptism by the words of the form. Nor is it essential for the Trinity to be signified by the manner in which the matter is used; although this is done to make the signification clearer.
In like manner Christ's death is sufficiently represented in the one immersion. And the three days of His burial were not necessary for our salvation, because even if He had been buried or dead for one day, this would have been enough to consummate our redemption: yet those three days were ordained unto the manifestation of the reality of His death, as stated above (Q[53], A[2]). It is therefore clear that neither on the part of the Trinity, nor on the part of Christ's Passion, is the trine immersion essential to the sacrament.
Reply to Objection 2: Pope Pelagius understood the trine immersion to be ordained by Christ in its equivalent; in the sense that Christ commanded Baptism to be conferred "in the name of the Father, and of the Son, and of the Holy Ghost." Nor can we argue from the form to the use of the matter, as stated above (ad 1).
Reply to Objection 3: As stated above (Q[64], A[8]), the intention is essential to Baptism. Consequently, one Baptism results from the intention of the Church's minister, who intends to confer one Baptism by a trine immersion. Wherefore Jerome says on Eph. 4:5 , 6 : "Though the Baptism," i.e. the immersion, "be thrice repeated, on account of the mystery of the Trinity, yet it is reputed as one Baptism."
If, however, the intention were to confer one Baptism at each immersion together with the repetition of the words of the form, it would be a sin, in itself, because it would be a repetition of Baptism.
