Last week was one of the strangest in Rome in recent memory. It began with the news that four cardinals had asked Pope Francis to answer five yes-or-no questions – known in Latin as dubia – about Amoris Laetitia, his exhortation on the family. They had submitted the queries in September, but decided to make them public now because they had received no reply. Then the Pope suddenly cancelled a meeting with the world’s cardinals scheduled for the end of the week. The Vatican offered no explanation, prompting speculation that the four cardinals were planning to raise the dubia at the gathering.
