I want to know the answer to the following question:
What practice differentiates the Angican Communon from Protestant churches at large?
All the background I'm provided with is that "The multiple churches that form the Anglican Communion and the Continuing Anglican movement have different views on Marian doctrines and venerative practices given that there is no single church with universal authority within the Communion and that the mother church (the Church of England) understands itself to be both "catholic" and "Reformed".". Is that enough to answer the question?
Answer: no
