Whether order is an impediment to matrimony?

Objections

Objection 1 : It would seem that order is not an impediment to matrimony. For nothing is an impediment to a thing except its contrary. But order is not contrary to matrimony. Therefore it is not an impediment thereto.
Objection 2 : Further, orders are the same with us as with the Eastern Church. But they are not an impediment to matrimony in the Eastern Church. Therefore, etc.
Objection 3 : Further, matrimony signifies the union of Christ with the Church. Now this is most fittingly signified in those who are Christ's ministers, those namely who are ordained. Therefore order is not an impediment to matrimony.
Objection 4 : Further, all the orders are directed to spiritual things. Now order cannot be an impediment to matrimony except by reason of its spirituality. Therefore if order is an impediment to matrimony, every order will be an impediment, and this is untrue.
Objection 5 : Further, every ordained person can have ecclesiastical benefices, and can enjoy equally the privilege of clergy. If, therefore, orders are an impediment to marriage, because married persons cannot have an ecclesiastical benefice, nor enjoy the privilege of clergy, as jurists assert (cap. Joannes et seqq., De cler. conjug.), then every order ought to be an impediment. Yet this is false, as shown by the Decretal of Alexander III (De cler. conjug., cap. Si Quis): and consequently it would seem that no order is an impediment to marriage.
