I want to know the answer to the following question:
What document did this group create once it was convened ?
All the background I'm provided with is that "The report "Mary: Faith and Hope in Christ", by the Anglican-Roman Catholic International Commission, concluded that the teaching about Mary in the two definitions of the Assumption and the Immaculate Conception can be said to be consonant with the teaching of the Scriptures and the ancient common traditions.". Is that enough to answer the question?
Answer: yes
