Whether consent given in words expressive of the future makes a marriage?

Objections

Objection 1 : It would seem that consent given in words expressive of the future makes a marriage. For as present is to present, so is future to future. But consent given in words expressive of the present makes a marriage in the present. Therefore consent given in words expressive of the future makes a marriage in the future.
Objection 2 : Further, in other civil contracts, just as in matrimony, a certain obligation results from the words expressing consent. Now in other contracts it matters not whether the obligation is effected by words of the present or of the future tense. Therefore neither does it make any difference in matrimony.
Objection 3 : Further, by the religious vow man contracts a spiritual marriage with God. Now the religious vow is expressed in words of the future tense, and is binding. Therefore carnal marriage also can be effected by words of the future tense.
