{Commentarii in Epistolam D. Pauli ad Ephesios, facili et perspicua methodo conscripti. A D. Benedicto Aretio bernensi theologo. Cum indice rerum memorabilium quae in hisce continentur. Posterior haec}

I constitute the principal genus category/type here as epanorthōtikon corrective. For it is certain that the Apostle wanted to correct the doctrine of truth corrupted by false teachers, which corruptions, had they not fallen into that Church, he would not have been writing such an Epistle. Now the corruptions were that some allowed themselves to be circumcised, that they were already keeping a choice of times, and certain other things, which he tries to root out from the Galatian Church, and in their place to substitute again that simple form of doctrine which he had originally left among them. Then there are the accessories, by which that principal genus is adorned and fulfilled: 1. apologētikon apologetic, concerning himself, his vocation, and his conversation with the Apostles. 2. elenktikon refutatory, in chapters 1, 3, and 4, by which he gravely blames them as inconstant, foolish, and superstitious. 3. didaktikon didactic, by which he confirms the justice of faith against the merits of works, the abrogation of the law, and similar things. 4. protreptikon exhortatory, by which he urges them to return to his doctrine, to the works of a reborn man, to beneficence, and similar virtues. 5. epainetikon laudatory, by which he praises the Galatians, ch. 4, verse 14. 6. parainetikon admonitory, in chapter 5, warning about necessary virtues. This method of constituting the genus has seemed to me most true and most apt.
