I want to know the answer to the following question:
What was the Secretariat for non-believers eventually renamed?
All the background I'm provided with is that "In 1964, Paul VI created a Secretariat for non-Christians, later renamed the Pontifical Council for Interreligious Dialogue and a year later a new Secretariat (later Pontifical Council) for Dialogue with Non-Believers.". Is that enough to answer the question?
Answer: yes
