Thomas Aquinas, Summa Theologiae, Third Part. 4 articles.
Read in the reading room → This question at New Advent
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 now to consider things that are preparatory to Baptism: and (1) that which preceded Baptism, viz. Circumcision, (2) those which accompany Baptism, viz. Catechism and Exorcism.
Concerning the first there are four points of inquiry:
(1) Whether circumcision was a preparation for, and a figure of, Baptism?
(2) Its institution;
(3) Its rite;
(4) Its effect.
Also online, linked only: the same translation at New Advent and the Latin text at Corpus Thomisticum. Neither is copied here.
