XVII–XX. Abundant, operating, preventing, and assisting grace
XVII. The calling of abundant grace is also called efficacious calling. It is called operating either because God works it in the human without the human, or because God through it also works alone and without the human or his consent, as He wills. It is also called preventing grace, because it altogether precedes human consent and is the help that God grants to a human still dead in sins, by illuminating his intellect or moving the will to saving acts.
XX. The calling of assisting grace is that by which the Holy Spirit aids a human already excited so that he wills, toward the good that he wills — so to speak — to be willed and perfected. This grace works willing in the human, but not without him consenting and cooperating in a human manner; yet so that the willing itself also is referred wholly to divine grace as its first principle. It is also called accompanying, consequent, and cooperating.
Latin
XVII. Abundantis gratiae vocatio dicitur etiam vocatio efficax. Operans dicitur, vel quia Deus eam in homine sine ipso operatur, vel quia Deus per eam etiam solus & sine homine seu eius consensu, ut velit, operatur. Dicitur & gratia praeveniens, quia omnino praevenit humanum consensum & est auxilium, quod Deus homini in peccatis adhuc mortuo largitur, intellectum eius illuminando aut voluntatem ad actus salutares movendo. XX. Adjuvantis gratiae vocatio est, qua Spiritus sanctus hominem jam excitatum, ut velit, juvat ad bonum quod vult, ut ita loquar, volendum & perficiendum. Haec gratia in homine operatur velle, sed non sine ipso consentiente & humano more cooperante: sic tamen, ut ipsum quoque velle in divinam gratiam, tanquam in primum eius principium, in solidum referatur. Dicitur etiam comitans, consequens & cooperans.
