Whether consent given secretly in words of the present makes a marriage?

Objections

Objection 1 : It would seem that consent given secretly in words of the present does not make a marriage. For a thing that is in one person's power is not transferred to the power of another without the consent of the person in whose power it was. Now the maid is in her father's power. Therefore she cannot by marriage be transferred to a husband's power without her father's consent. Wherefore if consent be given secretly, even though it should be expressed in words of the present, there will be no marriage.
Objection 2 : Further, in penance, just as in matrimony, our act is as it were essential to the sacrament. But the sacrament of penance is not made complete except by means of the ministers of the Church, who are the dispensers of the sacraments. Therefore neither can marriage be perfected without the priest's blessing.
Objection 3 : Further, the Church does not forbid baptism to be given secretly, since one may baptize either privately or publicly. But the Church does forbid the celebration of clandestine marriages (cap. Cum inhibitio, De clandest. despons.). Therefore they cannot be done secretly.
Objection 4 : Further, marriage cannot be contracted by those who are related in the second degree, because the Church has forbidden it. But the Church has also forbidden clandestine marriages. Therefore they cannot be valid marriages.
