Violence is not a modern phenomenon, nor is it a shameful mark of our time and culture. It appeared at the dawn of humanity, and cuts across the entire human history, and many researchers believe that it will continue into the distant future. In recent decades, violence against women and violence against and among children has received exceptional attention. Probably because of the vulnerability and symbolic status of a child in today's society. This paper deals with the phenomenon of violence with special emphasis on violence against children. With the aim of a better understanding of the phenomenon, its essential features are brought to light, such as definitions, most common forms, causes, and consequences. After getting to know the phenomenon, special importance is attached to prevention and the very delicate issue of intervention after violence that has occurred. In addition, the legal and moral analysis indicates the absolute unacceptability of violence against children, as well as the obligation of society and the Church to take a serious stand on the elimination of this shameful phenomenon that marks modern civilization. Since the Church is interested in solving and possibly eliminating the phenomenon of violence, the last chapter presents the Church's position, which explicitly condemns any form of violence. The dignity of children and the obligations of the Church in the face of violence against children are emphasized.
