Calixtus: hearing and weighing the Gospel is not above nature
Thesis XI. What the same author teaches elsewhere agrees with this. 'Note,' he writes, 'that once God has revealed the Gospel and has it preached by people far and wide among people, it is not beyond the strength of nature for someone to hear the Gospel, grasp it, think it over, and set it beside what others, Jews for instance or Muslims, put forward as revealed by God.'
This is in his judgment on the theological controversies in dispute between the Lutherans and the Reformed, number 33.

XI. Quibus consona sunt ea quae alibi tradit idem autor. Id autem observandum est, inquit, posito quod Deus Evangelium revelaverit, & passim inter homines praedicari faciat per homines, non esse supra vires naturae quod quis Evangelium audiat, concipiat, consideret, & cum iis quae ab aliis, Judaeis puta vel Mahumetanis, tanquam divinitus revelata proferuntur comparet. In judicio de controversiis Theologicis quae inter Lutheranos & Reformatos agitantur, num. 33.
