This work provides guidance for incorporating Catholic social teaching into the intellectual and pastoral formation of priests. It addresses how the doctrine of the Church should be studied, taught, and integrated within seminary curricula and ministerial preparation. The text is intended for educators, formators, and ecclesiastical institutions seeking a coherent approach to the Church’s social doctrine, with attention to its theological foundations and pastoral application. Presented in French, it serves as a reference for Catholic institutions engaged in priestly education and the transmission of Catholic social thought.
