"God does not will the damnation of anyone under the formality of damnation, nor anyone's death as death, because he wills all men to be saved, but he wills it under the formality of justice."

"Deus non vult damnationem alicuius sub ratione damnationis, nec mortem alicuius inquantum est mors, quia ipse vult omnes homines salvos fieri, sed vult ista sub ratione iustitiae."

     Thomas Aquinas, Summa theologiae I-II.19.10.ad 2, trans. Ralph McInerny (Thomas Aquinas:  selected writings, ed. & trans. Ralph McInerny (London:  Penguin Books, 1998), 600).  Latin from Corpus Thomisticum.
     And of course "under the formality of damnation [(sub ratione damnationis)]" = "with respect to the reason for willing [(quantum ad rationem voliti)]".  Cf. "under the common formality [(secundum rationem communem)]".  Both of the latter from ad 1.
