A plea to leave arduous questions aside
Thesis LXXX. The great variety of opinions and views on the nature and essence of efficacious grace, and on how it works in people's souls, which has occupied the Christian schools for so many centuries now, shows that the matter is tangled and obscure and full of difficulties on every side.
There is no hope that the disputes will end unless some limit is put to curiosity and hard, unnecessary questions are dropped. It would indeed be far wiser, and better for Christian peace and piety, to keep away from such questions altogether than to quarrel endlessly over matters that overwhelm the human mind by their difficulty and on which hardly anyone can satisfy himself.
Latin
LXXX. Caeterum tanta varietas sententiarum & opinionum circa naturam atque essentiam gratiae efficacis, & rationem ac modum quo in animis hominum operatur, quae a tot jam saeculis Scholas Christianas exercet, arguit rem esse perplexam, obscuram, & quae undique multis difficultatibus scatet: Nec spes est fore contentionum finem, nisi curiositati modus aliquis statuatur, & omittantur quaestiones arduae & non necessariae. Ac profecto longe consultius foret, & paci ac pietati Christianae conducibilius in totum ab ejusmodi quaestionibus abstinere, quam sine fine rixari de rebus, quae difficultate sua ingenium humanum obruunt, & in quibus vix quisquam sibi potest satisfacere.
