I want to know the answer to the following question:
What are the impermanent sources of positive ecclesiastical law?
All the background I'm provided with is that "In the Roman Church, universal positive ecclesiastical laws, based upon either immutable divine and natural law, or changeable circumstantial and merely positive law, derive formal authority and promulgation from the office of pope, who as Supreme Pontiff possesses the totality of legislative, executive, and judicial power in his person.". Is that enough to answer the question?
Answer: yes
