In November 2015, a conference was convened at the Centre in Vienna to celebrate the fiftieth anniversary of the Nostra Aetate declaration and to reflect on its impact on interreligious relations over the past 50 years.

Our Board of Directors, themselves representatives from major world religions, together with leading practitioners, joined us to corroborate the Declaration’s continuing and powerful contribution to public life in improving interreligious understanding and collaboration.

This book has been compiled to commemorate that occasion in reproducing the commentary from those leading experts in interreligious dialogue who spoke at the conference, including His Eminence Cardinal Christoph Schönborn, Bhai Sahib Mohinder Singh Ahluwalia, Prof. Dr. Ingeborg Gabriel, Univ. Prof. em. Dr. Susanne Heine, Mag. Dr. Markus Ladstätter, KAICIID Board Members Swami Agnivesh, Dr. Hamad Al-Majed, His Eminence Metropolitan Emmanuel, His Excellency Bishop Miguel Ángel Ayuso Guixot, mccj, Dr. Seyyed Ata’ollah Mohajerani, Rev. Kosho Niwano, Rev. Mark Poulson, Chief Rabbi David Rosen, Dr. Mohammad Sammak and KAICIID Advisers Prof. Mohammed Abu-Nimer and Prof. Patrice Brodeur, as well as Secretary General His Excellency Faisal bin Muaammar.
