In the seventies, Cardinal Stefan Wyszyński was not only the undisputed leader of the Polish Church, but also a widely respected authority in society, whose voice was of great importance. In the above analysis, the attitude of the „Primate of the Millennium” to the socio-political reality of the PRL was discussed. A comprehensive view of this hierarch was presented regarding the functioning of the communist system in Poland; his approach to the state-church relationship; to key political events (amendment to the constitution, events of June 1976, election of Cardinal Wojtyła as pope) and attitude to the rise and activity of the pre-August opposition. This analysis does not aspire to the full exhaustion of the topic, it focuses on issues most for Cardinal Wyszyński important in the socio-political sphere.
