Let no Christian therefore, whether philosopher or theologian, embrace eagerly and lightly whatever novelty happens to be thought up from day to day, but rather let him weigh it with painstaking care and a balanced judgment, lest he lose or corrupt the truth he already has, with grave danger and damage to his faith.
Quapropter christianus, sive philosophus, sive theologus, non festinanter ac leviter amplectatur quidquid novi in dies excogitatum fuerit, sed summa sedulitate id perpendat ac iusta in trutina ponat, ne adeptam veritatem amittat, vel corrumpat, gravi profecto cum ipsius fidei discrimine ac detrimento.vatican.va vatican.va
