Stephen Min Kuk-ka was a Korean Catholic catechist born in 1787 in Gyeonggi. After his family converted to the faith, he dedicated his life to religious instruction during a period when the Confucian government prohibited the spread of non-traditional beliefs. Despite facing significant personal losses, including the deaths of his wife and daughter, he remained committed to his mission. His work in converting others eventually led to his arrest by government authorities, resulting in his death in Seoul in 1840.
