Casting a light on one of the leading British scholars working in the field of Catholic Education Studies, this edited volume scrutinises contemporary issues surrounding the scholarship of John Sullivan over the past three decades, demonstrating the field's development under his scholarly influence. Giving voice to many internationally established and leading Catholic education scholars, chapters review and critically appraise the contribution of Sullivan's work in key areas such as his call for a coherent philosophy of Catholic education; a broader, more inclusive Catholic culture; robust teacher formation; and a coherent understanding of Catholic higher education. The book also discusses the interplay between the pastoral and the prophetic -- two complementary aspects that underpin much of Sullivan's work. Ultimately posing questions for how Catholic educators can and should build on Sullivan's foundational legacy, this book will appeal to scholars, researchers and postgraduate students in the fields of religious education, history of education and Catholic educational studies more broadly.
