John VII is elected pope. Born in the Byzantine Empire, John VII is the first pope whose father was an official with the Byzantine Imperial Court. What's more, his grandfather was a Senator. This means he has deep family connections with the court, a fact that probably helps him maintain peaceful relations with the emperor in Constantinople.
Peaceful, though, doesn't mean that everyone was happy. Pope John VII refuses to sign the canons of the Trullan Council which established traditions of the Church of Constantinople as orthodoxy, to the detriment of traditions and practices in Rome. For example, it authorizes married men to be ordained and priests and imposes excommunication on anyone who tries to separate a married priest from his wife or for any cleric who abandons his wife.
