Decem Theses III-IV: One Confession in two exemplars; Formula Concord insert differs in words, not substance
III. Those two exemplars are not two confessions, but one and the same: the later differs from the earlier not in the substance of the faith's articles, but only in wording and clearer explanation.
IV. The Augsburg Confession text slotted into the Formula of Concord does differ in some words from the 1531 Wittenberg printing in Luther's volumes; in substance, though, it fully matches that text.
Latin
III.
Duo illa exemplaria, non duplicem, sed unam eandemq; Confessionem continent, nec posterius à priori, substantialibus fidei articulis, sed solis verbis clariorique explicatione, differt.
IV.
Exemplar Augustanae Confessionis, Formulae Concordiae insertum, in quibusdam quidem verbis, ab eo, quod Wittebergae An. 31. impressum in Tomis Lutheri invenitur, est diversum; in substantialibus tamen plenè cum eodem convenit.
