Péter Melius Juhász was a Hungarian botanist, writer, theologist, and bishop of the Calvinist Reformed Church in Transylvania. He famously debated with Ferenc David in a series of synods resulting in the Brief Confession of Pastors at Debrecen (1567), the Confession of Kassa (1568), and the Várad disputation - held at "Várad", modern Nagyvárad, not Várad in Hungary. The "sententia catholica," was followed by a new confession, the Confession of Várad (1568).
