Ordinatio IV d. 46 q. 3 ad arg. princ. 4 (ed. Vat. XIV, 215-217):
To the second, it is said that mercy connotes something other than justice, although those two are unqualifiedly [simpliciter = realiter] the same as each other.
But against this: that connotation does not require some distinction of this kind from that as it is in itself, but only as it is understood [accipitur] and signified, because connotation is required for this. The argument, however, requires that there is some distinction between them [justice and mercy] as they are causes of distinct effects. Nor does the distinction of reason suffice for this, because a relation of reason is not that by which some effect is really made [efficitur], rather, generally, no real distinction in an effect depends on a relation of reason in a cause, just as was proved in d. 13 of the first book. That distinction of effects depends essentially on a distinction in the cause, therefore that is not only one of reason.
I concede, therefore, to that argument that just as in God the intellect is not formally the will, nor contrariwise, although one is the same as the other by the truest identity of simplicity, so also justice is not formally the same as mercy or contrariwise. And according to this formal non-identity, that [= mercy] can be the proximate principle of some external [= extra] effect, of which the other [= justice] is not the principle, in the way in which just as if this and that [= mercy and justice] were two things [res] because to be a formal principle befalls each as it is formally such.
Contra: the divine esse is most actual, therefore it includes every divine perfection; but it would not include, if there were a formal distinction there, because everything distinct formally is there actually, and consequently, as distinct, it is there in act, and so the essence as distinct does not include every act.
Again, if there are there real distinct formalities, therefore there are distinct realities there, and so distinct things [res]. Proof of the first consequence: because formality is distinct by its own reality.
To the first: the divine esse contains every actuality of the divine essence unitively. [Entities] are not contained unitively which are contained without all distinction, becuase union is not wihout all distinction; nor are they contained unitively which are contained as unqualifiedly [simpliciter] really distinct, because are contained in a multiple manner or separately [dispersim]. Therefore this term 'unitive' includes some distinction of the [entities] contained, which suffices for union, and nevertheless such a union which is repugnant toall composition and aggregation of the distinct [entities]. This can not be unless there be posited formal non-identity with real identity.
To the argument, therefore, I concede that the essence contains every actuality, and consequently every formality, but not as formally the same, becaues then they would not be contained unitively.
To the second it can be said that as many formalities as are there, so many are there realities and things [res]; but each reality is only qualified [secundum quid], just as was shown there [Ord. I d. 13, according to the Vat. editors]. Otherwise, that consequence can be denied: 'many real formalities, therefore many realities', just as 'many divine persons, therefore many deities', is denied. But the first response is more real [realier].
