This paper is about Catholic subjectivity and teacher education. We explore multiple notions of Catholic subjectivity drawing from their Korean, Irish American, and Filipino-Polish heritages. Lived religion and memory writing are conceptual and methodological foundations of this paper. We examine multiple meanings of Catholic subjectivity via self-reflexive investigations on self, others, and the community in diverse sociocultural contexts. We argue that attention to teacher subjectivity with spirituality is deeply aligned with promoting the public good, such as advancing diversity and social justice issues in teacher education.
