From the Supplement, compiled after Aquinas’s death from his Commentary on the Sentences and transcribed here from the 1917 to 1922 printings. About the Supplement.
Text: Summa Theologiae, Supplement to the Third Part (Supplementum Tertiae Partis), transcribed from Internet Archive scans, translated by the Fathers of the English Dominican Province. The Supplement, compiled after Aquinas’s death from his earlier Commentary on the Sentences, in the same English Dominican translation as the Gutenberg Parts. Transcribed by Bibliotheca Catholica from the OCR of four Internet Archive scans of the pre-1931 printings (Questions 1 to 33 from the 1917 Washbourne and Benziger volume, 34 to 68 from the 1922 volume, 69 to 86 from the 1921 volume, and 87 to 99 from the 1922 Benziger volume), with OCR errors corrected and doubtful passages marked, not rewritten. 99 questions and 446 articles. The two appendices printed after Question 99 are not included. Sources, SHA-256 of each OCR file, and the method are in the source record. Rights: Public domain (US)
The Supplement is not a Project Gutenberg text. It is Bibliotheca Catholica’s transcription of public-domain scans at the Internet Archive; obvious OCR errors were corrected, and passages marked “OCR uncertain” could not be confidently corrected, so check them against the linked scan page.
In the next place we must consider those things which are annexed to marriage: (i) the payment of the marriage debt; (2) plurality of wives; (3) bigamy; (4) the bill of divorce; (5) illegitimate children.
Under the first head there are ten points of inquiry: (i) Whether one spouse is bound to pay the marriage debt to the other? (2) Whether one is sometimes bound to pay without being asked? (3) Whether a wife may demand the debt during the menses? (4) Whether she is bound to pay it at that time? (5) Whether husband and wife are equal in this matter? (6) Whether the one without the other's consent may take a vow that prohibits the payment of the debt? (7) Whether it is forbidden to ask for the debt at any particular time? (8) Whether it is a mortal sin to ask for it at a holy time? (9) Whether it is an obligation to pay it at the time of a festival? (10) Whether weddings should be forbidden at certain times?
