Summa Theologiae · III, q. 75
Question 75. Of the Change of Bread and Wine into the Body and Blood of Christ
Thomas Aquinas, Summa Theologiae, Third Part. 8 articles.
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.

We have to consider the change of the bread and wine into the body and blood of Christ; under which head there are eight points of inquiry:
(1) Whether the substance of bread and wine remain in this sacrament after the consecration?*
(2) Whether it is annihilated?
(3) Whether it is changed into the body and blood of Christ?
(4) Whether the accidents remain after the change?
(5) Whether the substantial form remains there?
(6) Whether this change is instantaneous?
(7) Whether it is more miraculous than any other change?
(8) By what words it may be suitably expressed?
[*The titles of the Articles here given were taken by St. Thomas from his Commentary on the Sentences (Sent. iv, D, 90). However, in writing the Articles he introduced a new point of inquiry, that of the First Article; and substituted another division of the matter under discussion, as may be seen by referring to the titles of the various Articles. Most editions have ignored St. Thomas's original division, and give the one to which he subsequently adhered.]
