I'm just curious how that was supposed to have worked. I'm not saying yes or no, I just want to learn more about this theory. I realize that Christianity spread at the same time that Rome was diminishing, but correlation does not mean causation. I'm very curious what the reasoning/evidence is behind this theory. Thanks
The story that comes to my mind is about Pope Leo the Great. During the sack of Rome in 455 by the Vandals, Pope Leo I is credited with negotiating with the invaders to prevent further destruction and violence. Additionally, he worked to alleviate the suffering of the Roman population by distributing food and providing aid. He handled the inevitable legal disputes and dealt with criminals. That doesn't sound to me like bringing down Rome, but rather, keeping it propped up.
