When Yves Congar wrote his most important works on the Holy Spirit, Je crois en l'Esprit Saint (1979-1980) and La Parole et le Souffle (1984) he was well aware of the historical circumstances within which he was writing. After the Second Vatican Council had renewed the Church's view of itself, what needed development was the penumatological character of ecclesiology, a pneumatological ecclesiology that in Congar's view was closely linked both to a pnuematological anthropology and to christology. Both Congar's ecumenical experience and his study of history on the one hand, and the emergence of the movement of charismatic renewal in his own time, had made Congar convinced of these needs, and he devoted the last years of his life to work on these topics. In the four decades that have passed since Congar's death, the Church has developed into a more synodal Church in which the working of the Holy Spirit in ecclesial and personal processes of discernment has received a lot of ecclesial attention. This paper will discuss the contribution Congar's pneumatology can make to a synodal Church.
