I want to know the answer to the following question:
What is lacking in Protestantism, according to the Roman Catholic Church?
All the background I'm provided with is that "The view of the Roman Catholic Church is that Protestant denominations cannot be considered churches but rather that they are ecclesial communities or specific faith-believing communities because their ordinances and doctrines are not historically the same as the Catholic sacraments and dogmas, and the Protestant communities have no sacramental ministerial priesthood and therefore lack true apostolic succession.". Is that enough to answer the question?
Answer: yes
