The Multicultural and Social Justice Counseling Competencies (MSJCC; Ratts, Singh, Nassar‐McMillan, Butler, & McCullough, 2015) provide recommendations for social justice advocacy through a socioecological lens. The authors conceptualize and apply the MSJCC to inform counselor engagement in social justice advocacy for an often‐neglected area of diversity: religion and/or spirituality. Practice and ethical examples, considerations, and recommendations related to religion and/or spirituality in MSJCC‐compatible social justice advocacy are provided.
