Answer: C . Christian leaders took over some of the authority that had traditionally belonged to Roman emperors
Step-by-step explanation:
The Roman Emperor was to have absolute power over the affairs of the empire including religious activities. With Christianity becoming so powerful in Rome however, the Clergy was able to take over some of the authority that the Roman emperor traditionally held such as power over religion.
This is shown in this except where Bishop Ambrose told the emperor that he had no jurisdiction over matters of faith and so could not instruct him(Bishop) on what to do when it came to religious activities.
