This paper explores some of the documents that provide a foundation for the Church and its ministries to deliver justice and mercy to all, including students with disabilities. First, Catholic Social Teaching (CST) traditions will be presented as the foundation to some of the documents of the American Church. A chronology of the documents of United States bishops will trace the flow of CST as the impetus for designing and delivering programs for students with disabilities in Catholic schools. Implications for Catholic schools are outlined for next steps for implementation. [Note: The page range (5-22) shown via the .pdf is incorrect. The correct page range is 5-23.]
