ST Suppl., q. 46
Of the Consent to which an Oath or Carnal Intercourse is Appended
Supplement — compiled posthumously from Aquinas's early Sentences commentary

(1) Whether an oath added to the consent that is expressed in words of the future tense makes a marriage?
(2) Whether carnal intercourse supervening to such a consent makes a marriage?
