He also maintained close ties with Gaul and the church hierarchy there, sending legates to convene synods. His short but impactful pontificate strengthened papal influence in both East and West. Hilarius died on February 29, 468, leaving a legacy of strict church discipline.

Returning to Scotland, he openly preached the new doctrines of justification by faith, challenging the Catholic establishment.

Hennenberger's dual expertise in theology and cartography reflected the Renaissance spirit of interdisciplinary scholarship. He corresponded with other learned figures of his day, exchanging data on local histories and mapmaking techniques. His contributions laid groundwork for future cartographers and preserved knowledge of 16th-century Prussian lands. Hennenberger died on February 29, 1600, remembered for his clerical service and scholarly mapping.
