Johannes Oecolampadius

Johannes Oecolampadius (also ''Œcolampadius'', in German also Oekolampadius, Oekolampad; 1482 – 24 November 1531) was a German Protestant reformer in the Calvinist tradition from the Electoral Palatinate. He was the leader of the Protestant faction in the Baden Disputation of 1526, and he was one of the founders of Protestant theology, engaging in disputes with Erasmus, Huldrych Zwingli, Martin Luther and Martin Bucer. Calvin adopted his view on the Eucharist dispute (against Luther).

His German surname was ''Hussgen'' (or ''Heussgen'', ''Huszgen''), which he etymologized to ''Hausschein'' ("house-shine") and hellenized (as was the custom at the time) to Οἰκολαμπάδιος in all capital letters, without Greek diacritics, as may be seen in , quoting a verse of Johannes Rhellicanus. In modern times, his name has been published in lowercase using polytonic diacritics, viz. () in ''katharevousa'' publications associated with the Greek Orthodox Church, e.g.; otherwise, it is spelled Οικολαμπάδιος in Modern Greek, including at Greek Wikipedia.}}(''Oikolampádios'', from οἶκος ''oîkos'', "house," and λαμπάς ''lampás'', "torch, lamp", and -ιος, ''-ios'', "pertaining to"; this was then Latinised as ''Oecolampadius''). argues in favour of the long-standing suggestion that the name is simply derived from a dialectal form of ''Häuschen'', i.e. the diminutive of ''Haus'' "house".}} Provided by Wikipedia
