John Trapp on Hosea 2:20

Verſe 20. I will even betroth thee unto me in faithfulneſſe] Tremellius, Druſius, and Tarnonius render it in fide in faith, and interpret it of de fide vera et ſalvifica of that true juſtifying faith whereby we are united to Chriſt: And for this they urge the next words, as an Expoſition of theſe. And they ſhall ſhall know the Lord: alledging ſome other texts of Scripture wherein ſaving knowledge is put for juſtifying faith, as Eſay 53.11. Jer. 31.33. Job. 17.3. The Septuagint alſo render it [non-Latin text not transcribed].Tarnou. in exer. cit. Biblic. See Maſter Dugards treatiſe called The change. Now [non-Latin text not transcribed] is the New Teſtament is oft uſed for ſaving and growing faith Tit. 1.1. Col. 2.1. and 3 10. which indeed is the bond of the ſpirituall marriage: and is it ſelf nothing elſe but a fiduciall aſſent preſuppoſing knowledge. For man is a rationall creature, faith a prudent thing, comprehending in it ſelf theſe three acts: 1 knowledge in the underſtanding. 2. Aſſent or rather Conſent in the Will. 3. Truſt or confidence in the heart; certainty of Adherence: if not of Evidence. The Papiſts faſten faith in the will, as in the adaequate ſubject, that they may the mean while do what they will with the underſtanding and the heart. To which purpoſe they exclude all knowledge, & deteſt Truſt in Chriſts promiſes, expunging the very name of it every where by their Indices Expurgatorij. A blind belief as the Church beleeves is as much as they require of their miſled and muzzled Proſelytes. Bellarmine ſaith that faith may far better be defined by ignorance then by knowledge. But how ſhall men beleeve on him of whom they have not heard? Let us leave to the Papiſts, their implicit faith and their blind obedience: and cry after Chriſt as that poor man did. Lord that mine eyes might be opened, and that I may know the Lord] yea grow in grace and in the knowledge of our Lord Jeſus Chriſt. Theſe things have I written unto you (ſaith Saint John to thoſe that were no Babyes or Zanyes in faith or knowledge) that beleeve on the name of the Son of God that ye may know that ye have eternall life, and that ye may (yet more) beleeve in the Son of God. 1 John. 5.13. David though he had proceeded further in the diſcovery of Divine truthes then thoſe before him, Pſal. 119.99. yet he was ſtill to ſeek of that which might be known ver. 96. Even as thoſe great diſcoverers of the new-found lands in America were wont to confeſſe at their return, that there was ſtill a Plus-ultra more yet to be diſcovered.
