Text: Summa Theologiae, Project Gutenberg #19950, Third Part (Tertia Pars), translated by the Fathers of the English Dominican Province. The Third Part of the Summa in the English Dominican translation (first printed 1911 to 1925; second and revised edition from 1920). A sample check on 2026-11-09 against pre-1931 printings at the Internet Archive (first printings of 1915 and 1916 and the second and revised edition of the 1920s) found that the article text matches, with no 1947 introduction, synopsis, or index. The phrase “From the Complete American Edition” in Gutenberg's catalog title is a provenance note only. Question and article numbers were added by the transcriber. The Gutenberg text ends at question 90 of the Third Part, where Aquinas stopped writing; the Supplement is a separate edition here, transcribed from 1917 to 1922 printings of the same translation.

Objection 1: It seems that several priests cannot consecrate one and the same host. For it was said above (Q. 67, A. 6), that several cannot at the same time baptize one individual. But the power of a priest consecrating is not less than that of a man baptizing. Therefore, several priests cannot consecrate one host at the same time.

Obj. 2: Further, what can be done by one, is superfluously done by several. But there ought to be nothing superfluous in the sacraments. Since, then, one is sufficient for consecrating, it seems that several cannot consecrate one host.

Obj. 3: Further, as Augustine says (Tract. xxvi in Joan.), this is "the sacrament of unity." But multitude seems to be opposed to unity. Therefore it seems inconsistent with the sacrament for several priests to consecrate the same host.

On the contrary, It is the custom of some Churches for priests newly ordained to co-celebrate with the bishop ordaining them.

I answer that, As stated above (A. 1), when a priest is ordained he is placed on a level with those who received consecrating power from our Lord at the Supper. And therefore, according to the custom of some Churches, as the apostles supped when Christ supped, so the newly ordained co-celebrate with the ordaining bishop. Nor is the consecration, on that account, repeated over the same host, because as Innocent III says (De Sacr. Alt. Myst. iv), the intention of all should be directed to the same instant of the consecration.

Reply Obj. 1: We do not read of Christ baptizing with the apostles when He committed to them the duty of baptizing; consequently there is no parallel.

Reply Obj. 2: If each individual priest were acting in his own power, then other celebrants would be superfluous, since one would be sufficient. But whereas the priest does not consecrate except as in Christ's stead; and since many are "one in Christ" (Gal. 3:28); consequently it does not matter whether this sacrament be consecrated by one or by many, except that the rite of the Church must be observed.

Reply Obj. 3: The Eucharist is the sacrament of ecclesiastical unity, which is brought about by many being "one in Christ."
