Annotatio VI §.I: Recognized Fraternity — Marburg/Rinteln/Cassel; Sendomir; Reformeds profess; Lutherans held by fear of schism
So there is no doubt: the Reformed once recognized fraternity with these Lutherans — in Germany at Cassel among Marburgers and Rintelners, and in Poland at Sendomir among Augsburg, Bohemian, and Helvetic confessionists.
They still openly profess that Christian fraternity with such Lutherans.
These Lutherans have joined heart and mind to the Reformed in brotherly love, even if more secretly — held back from an external profession by fear of schism with the rest of their own.
Latin
Unde dubium non est, quòd sicuti Reformatis agnita quondam Lutheranorum horum secum inita Fraternitas, tùm in Germania inter Marpurgenses & Rintelenses, Cassellis, tùm in Polonia inter Augustana, Bohemica & Helvetica Confessionis, Sendomiriae est; Reformati etiam hodieque, ut semper aliàs, cum hujusmodi Lutheranis Fraternitatem Christianam sibi intercedere apertè profitentur; Ita non minus Lutheranos hos, corda animosque suos, cum Reformatis fraterno amore, etsi occultius conjunxisse, ab externa licèt Fraternitatis professione, metu Schismatis, quô reliqui Lutherani à se scinderentur, cohibiti.
