I want to know the answer to the following question:
Who was President of the Christian Unity Secretariat?
All the background I'm provided with is that "Cardinal Augustin Bea, the President of the Christian Unity Secretariat, always had the full support of Paul VI in his attempts to ensure that the Council language was friendly and open to the sensitivities of Protestant and Orthodox Churches, whom he had invited to all sessions at the request of Pope John XXIII.". Is that enough to answer the question?
Answer: yes
