I want to know the answer to the following question:
What  problem did the teacher's publication solve for the Holy Roman leader with act that was committed  to do in response to the actions of the teacher  ?
All the background I'm provided with is that "Spada furnished an interpretation whereby Pius IX was relieved of the problem of seeming to foster a doctrine not in agreement with the Aquinas' teaching.". Is that enough to answer the question?
Answer: yes
