He was ordained in 1588, when he was also appointed to the canon"s position formerly held by Primož Trubar. In 1597 he was appointed bishop of Ljubljana, and the appointment was confirmed in 1599. However, Jurij Dalmatin"s Bible translation was retained and he received papal permission to use it, thereby preserving its linguistic and literary tradition.
From 1614 to 1621 he served as the deputy provincial sovereign.
Chrön wanted to establish a press in Ljubljana. He made it possible for Johannes Tschandek (Slovene: Janez Čandek or Čandik) to print the gospels and epistles (Evangelia inu listuvi, 1613), and he copyedited the text himself, which was based on translations by Trubar and Dalmatin.
He established the Collegium Marianum in Gornji Graduate for the education of clergy. Chrön also supported liturgical music: he commissioned a new organ in Gornji Graduate.
Chrön died in Gornji Graduate, where he was also buried.
