Whether it is possible to be dispensed from a solemn vow of continency?

Objections

Objection 1 : It would seem that it is possible to be dispensed from a solemn vow of continency. As stated above, one reason for granting a dispensation from a vow is if it be an obstacle to a greater good. But a vow of continency, even though it be solemn, may be an obstacle to a greater good, since the common good is more God-like than the good of an individual. Now one man's continency may be an obstacle to the good of the whole community, for instance, in the case where, if certain persons who have vowed continency were to marry, the peace of their country might be procured. Therefore it seems that it is possible to be dispensed even from a solemn vow of continency.
Objection 2 : Further, religion is a more excellent virtue than chastity. Now if a man vows an act of religion, e.g. to offer sacrifice to God he can be dispensed from that vow. Much more, therefore, can he be dispensed from the vow of continency which is about an act of chastity.
Objection 3 : Further, just as the observance of a vow of abstinence may be a source of danger to the person, so too may be the observance of a vow of continency. Now one who takes a vow of abstinence can be dispensed from that vow if it prove a source of danger to his body. Therefore for the same reason one may be dispensed from a vow of continency.
Objection 4 : Further, just as the vow of continency is part of the religious profession, whereby the vow is solemnized, so also are the vows of poverty and obedience. But it is possible to be dispensed from the vows of poverty and obedience, as in the case of those who are appointed bishops after making profession. Therefore it seems that it is possible to be dispensed from a solemn vow of continency.
