Yep. Pretty much preaching what Jesus taught when he said "turn the other cheek"(Matthew 5:38) as well as  "blessed are the peacemakers"(Matthew 5:9). What made Jesus's teaching even more radical was he was living under a brutal and oppressive Roman occupation where many people(i.e the Zealots) were tempted to launch a military revolt against the Romans. Christ stuck to Nonviolence. 

That's the God we worship, a God of nonviolence who nonviolently hung on a brutal cross while he said about his enemies "Father forgive them for they know not what they do". Francis is bringing that God out in the open and basically following his name sake, St Francis of Assisi who stressed peace and nonviolence during an era when there was so much violence(the Crusades).
