Whether it was ever lawful to have several wives?

❌ Objection 1 : It would seem that it can never have been lawful to have several wives. For, according to the Philosopher (Ethic. v, 7), "The natural law has the same power at all times and places." Now plurality of wives is forbidden by the natural law, as stated above (Article [1]). Therefore as it is unlawful now, it was unlawful at all times.

❌ Objection 2 : Further, if it was ever lawful, this could only be because it was lawful either in itself, or by dispensation. If the former, it would also be lawful now; if the latter, this is impossible, for according to Augustine (Contra Faust. xxvi, 3), "as God is the founder of nature, He does nothing contrary to the principles which He has planted in nature." Since then God has planted in our nature the principle that one man should be united to one wife, it would seem that He has never dispensed man from this.

❌ Objection 3 : Further, if a thing be lawful by dispensation, it is only lawful for those who receive the dispensation. Now we do not read in the Law of a general dispensation having been granted to all. Since then in the Old Testament all who wished to do so, without any distinction, took to themselves several wives, nor were reproached on that account, either by the law or by the prophets, it would seem that it was not made lawful by dispensation.

❌ Objection 4 : Further, where there is the same reason for dispensation, the same dispensation should be given. Now we cannot assign any other reason for dispensation than the multiplying of the offspring for the worship of God, and this is necessary also now. Therefore this dispensation would be still in force, especially as we read nowhere of its having been recalled.

❌ Objection 5 : Further, in granting a dispensation the greater good should not be overlooked for the sake of a lesser good. Now fidelity and the sacrament, which it would seem impossible to safeguard in a marriage where one man is joined to several wives, are greater goods than the multiplication of the offspring. Therefore this dispensation ought not to have been granted with a view to this multiplication.
