Social work and Christian spirituality cannot be sharply separated from each other. The roots of social assistance are an important part of Christian morality and the teachings of the Bible. At the same time, in almost all of the Christian denominations, you can also find lay assistance, which provides help to those in trouble, nourished by the practical faith of the churches. In my paper, I examine the possibilities of Christian-based lay assistance and social assistance, as well as the relationship between spirituality and social work, using the example of the social and charitable activities of Calvary Chapel Hungary. It is important to recognize that lay help without professional social skills can sometimes cause more harm than good, but it is also true that professional social work can also be enriched by a commitment to help stemming from faith in God.
