Yes. The end of all things is something extrinsic to them because God is outside the entire order of the universe.
Finis rerum est quoddam bonum extrinsecum quia Deus ipse est extra totum ordinem universi.
A good existing in the universe, namely, the order of the universe, is an end thereof; this, however, is not its ultimate end, but is ordered to the extrinsic good as to the end: thus the order in an army is ordered to the general, as stated in Metaph. xii, Did. xi, 10.
Finis quidem universi est aliquod bonum in ipso existens, scilicet ordo ipsius universi; hoc autem bonum non est ultimus finis, sed ordinatur ad bonum extrinsecum ut ad ultimum finem; sicut etiam ordo exercitus ordinatur ad ducem, ut dicitur in XII Metaphys.
The universal end of all things is the Universal Good, Which is good of Itself by virtue of Its Essence, Which is the very essence of goodness; whereas a particular good is good by participation. Now it is manifest that in the whole created universe there is not a good which is not such by participation. Wherefore that good which is the end of the whole universe must be a good outside the universe.
Bonum autem universale est quod est per se et per suam essentiam bonum, quod est ipsa essentia bonitatis; bonum autem particulare est quod est participative bonum. Manifestum est autem quod in tota universitate creaturarum nullum est bonum quod non sit participative bonum. Unde illud bonum quod est finis totius universi, oportet quod sit extrinsecum a toto universo.
As the end of a thing corresponds to its beginning, it is not possible to be ignorant of the end of things if we know their beginning. Therefore, since the beginning of all things is something outside the universe, namely, God, it is clear from what has been expounded above (Q44, A1; Q44, A2), that we must conclude that the end of all things is some extrinsic good. This can be proved by reason.
Cum finis respondeat principio, non potest fieri ut, principio cognito, quid sit rerum finis ignoretur. Cum igitur principium rerum sit aliquid extrinsecum a toto universo, scilicet Deus, ut ex supra dictis patet, necesse est quod etiam finis rerum sit quoddam bonum extrinsecum. Et hoc ratione apparet.
