I want to know the answer to the following question:
How did the Holy Roman Church rule on the matter of the festivals ?
All the background I'm provided with is that "By the end of the 15th century the belief was widely professed and taught in many theological faculties, but such was the influence of the Dominicans, and the weight of the arguments of Thomas Aquinas (who had been canonised in 1323 and declared "Doctor Angelicus" of the Church in 1567) that the Council of Trent (1545–63)—which might have been expected to affirm the doctrine—instead declined to take a position.". Is that enough to answer the question?
Answer: no
