What defines diakonia? What must diakonia employees know about the theological content of diakonia? Does diaconal action presuppose the Christian faith? Such questions are addressed in diaconal training and further education, reflecting on the current conditions of diaconal activities. As simple as these questions may sound, they are difficult to answer. However, in order to conduct diaconal educational offerings, thorough didactic reflection is necessary: What is the essential core of "diaconal"? Can diakonia even be "conveyed"? What does "diaconal education" mean in the context of organized diakonia? The author reflects on fundamental didactic questions in this previously neglected area of diaconal education.
