I’ve remarked on Zanchi’s fourth section on the Trinity previously, so I will be brief here.
IIII. Essentiales proprietates in Deo reipsa non differe ab essentia. Agnoscimus enim in Deo propter eius simplicitatem essentiales proprietates re ipsa non differre ab essentia ac proinde illas sine hac communicari non posse ulli creaturae, eoque nec ullam creaturam vere esse dicive posse simpliciter (exempli causa) omnipotentem, simpliciter bonam, iustam, sapientem et id genus alia. Quemadmodum et Dominus Iesus de uno attributo loquens de omnibus docuit, dicendo: ‘Nemo bonus (simpliciter) nisi Deus’.
IIII: That in God, the essential properties in fact do not differ from the essence.
For we recognize that in God, on account of his simplicity, the essential properties do not in fact differ from the essence; and that, consequently, they are not able to be communicated to any creature without it; and that, for that reason, no creature truly is, or is able to be called, simply omnipotent (for example), simply good, just, wise, and other things of this kind, just as the Lord Jesus too, though speaking about only one attribute, taught about them all, when he said, “No one is good (simply) but God.” 1
