In the next place we have to consider the consent; and the first point to discuss is the consent considered in itself; the second is the consent confirmed by oath or by carnal intercourse; the third is compulsory consent and conditional consent; and the fourth is the object of the consent.
Under the first head there are five points of inquiry:
A Whether the consent is the efficient cause of matrimony?
A Whether the consent needs to be expressed in words?
A Whether consent given in words expressive of the future makes a marriage?
A Whether consent given in words expressive of the present, without inward consent, makes a true marriage outwardly?
A Whether consent given secretly in words expressive of the present makes a marriage?
