Ad Limina Apostolorum

The book details Karl Barth's pilgrimage to Rome in 1966, following his health improvement, to gain insight into the Catholic Church's understanding of the decisions made during Vatican II. Invited as an observer but unable to attend due to illness, Barth's journey reflects his deep interest in Christian unity and ecumenical dialogue. His visit highlights the significance of the Council's decisions and his desire to engage with the Catholic tradition at its core.
