XXIV. Quibus consona docet Wendelinus Christianae Theologiae lib. 2. cap. 24. ubi haec est ejus undecima Thesis: Proprium, principale, & proximum objectum Fidei est promissio Evangelica de peccatis per & propter Christi mortem expiatis, omnibusque peccatoribus poenitentibus & credentibus, propter Christum crucifixum fide apprehensum, in gratiam ex misericordia receptis; hanc promissionem in specie singuli fideles per fidem sibi applicant, & sic ad salutem dicuntur credere. Quibus hanc subjungit explicationem, Fidei justificantis objectum proprium est Christus pro nobis, me, te, crucifixus, & gratuita remissio peccatorum propter Christi mortem, & fusum pro nobis sanguinem, singulis per fidem applicanda; quae alias appellatur specialis misericordia.
