Yes. It was right for the woman to be made from a rib of man, to signify the social union of man and woman.
Conveniens fuit mulierem formari de costa viri, ad significandum quod inter virum et mulierem debet esse socialis coniunctio.
Some say that the woman's body was formed by a material increase, without anything being added; in the same way as our Lord multiplied the five loaves. But this is quite impossible. For such an increase of matter would either be by a change of the very substance of the matter itself, or by a change of its dimensions. Not by change of the substance of the matter, both because matter, considered in itself, is quite unchangeable, since it has a potential existence, and has nothing but the nature of a subject, and because quantity and size are extraneous to the essence of matter itself.
Quidam dicunt per multiplicationem materiae absque alterius additione, formatum fuisse corpus mulieris; ad modum quo dominus quinque panes multiplicavit. Sed hoc est omnino impossibile. Multiplicatio enim praedicta aut accidit secundum transmutationem substantiae ipsius materiae; aut secundum transmutationem dimensionum eius. Non autem secundum transmutationem substantiae ipsius materiae, tum quia materia in se considerata, est omnino intransmutabilis, utpote existens in potentia, et habens solum rationem subiecti; tum etiam quia multitudo et magnitudo sunt praeter essentiam ipsius materiae.
Wherefore multiplication of matter is quite unintelligible, as long as the matter itself remains the same without anything added to it; unless it receives greater dimensions. This implies rarefaction, which is for the same matter to receive greater dimensions, as the Philosopher says (Phys. iv). To say, therefore, that the same matter is enlarged, without being rarefied, is to combine contradictories --viz. the definition with the absence of the thing defined.
Et ideo nullo modo potest multiplicatio materiae intelligi, eadem materia manente absque additione, nisi per hoc quod maiores dimensiones accipiat. Hoc autem est rarefieri, scilicet materiam eandem accipere maiores dimensiones, ut philosophus dicit in IV Physic. Dicere ergo materiam multiplicari absque rarefactione, est ponere contradictoria simul, scilicet definitionem absque definito.
Wherefore, as no rarefaction is apparent in such multiplication of matter, we must admit an addition of matter: either by creation, or which is more probable, by conversion. Hence Augustine says (Tract. xxiv in Joan.) that "Christ filled five thousand men with five loaves, in the same way as from a few seeds He produces the harvest of corn"--that is, by transformation of the nourishment. Nevertheless, we say that the crowds were fed with five loaves, or that woman was made from the rib, because an addition was made to the already existing matter of the loaves and of the rib.
Unde, cum non appareat rarefactio in talibus multiplicationibus, necesse est ponere additionem materiae, vel per creationem; vel, quod probabilius est, per conversionem. Unde Augustinus dicit, super Ioan., quod "hoc modo Christus ex quinque panibus satiavit quinque millia hominum, quomodo ex paucis granis producit multitudinem segetum"; quod fit per conversionem alimenti. Dicitur tamen vel ex quinque panibus turbas pavisse, vel ex costa mulierem formasse, quia additio facta est ad materiam praeexistentem costae vel panum.
