A Reformed pastor, Molnár travelled widely during his life, visiting and studying in a number of European centres of the Reformation. His metrical translation of the Psalms was inspired by the German-language Lobwasser Psalter and was published in Herborn in 1607. (The Reformed Christian legal theorist Johannes Althusius had published his Politics in Herborn a few years earlier but had moved to Emden before Molnár's arrival.) He died in Kolozsvár in Hungarian Transylvania, now Cluj-Napoca, Roumania.
