Saint Mirin was a sixth-century Irish monk and missionary who played a significant role in the Christianization of western Scotland. Originally trained at Bangor Abbey in County Down under the guidance of Comgall, he eventually served as its prior. He later traveled to Scotland, where he established a religious community that eventually grew into Paisley Abbey. Recognized as a glorious confessor, he is celebrated as the patron saint of Paisley and the Roman Catholic diocese of the same name.
