The doctrine of friendship with God is one of the most classical in the Christian tradition. Building on the teachings of the Fathers of the Church and of the Middle Ages, the Theology of the Siglo de Oro explored its meaning in greater depth, stimulated also by the Decree on Justification of the Council of Trent, which places this theme in the context of its reflection on grace. Outstanding among the authors of that epoch was the Jesuit, F. Toledo , (...)
