There's so many ways Madara is meant to be a representation of Jesus Christ and reference him, that I've started thinking about how this makes Hashirama his Judas in some ways. Hashirama was the person close to him who ends up backstabbing the divine
"Savior" who is currently in human form (Judas figuratively and Hashirama literally) and causing him to go to his death, and then resurrect later (complete with the cave he was "dead" in for some time before resurrecting), etc.
It's a bit more complex than that because Kishimoto loves an inversions of myths (much more than referencing them uninverted, in Naruto at least) and because there's other stories and belief systems being represented here.
During the war, Madara tells Hashirama about how Kaguya ate the first chakra fruit from the Divine Tree despite it not being allowed, and that this was the source of how chakra was spread to all humans who have chakra today. Kaguya eating the fruit is a very direct parallel to the story of the Original Sin, with Kaguya as the primordial mother Eve. Madara says to Hashirama, "From the time people tasted up the fruit, humans have been cursed and destined to hate each other even more."
This is also making me think more about Hashirama calling Madara his "gift from the divine". In Christianity, Jesus is popularly considered to be "God's greatest gift" to humanity. More specifically, God's greatest gift to the world is commonly said to be him sending his one and only Son Jesus to earth to get killed as a human and then resurrected as God for humanity's sins, so that humans may receive salvation from their sins. This is very in line with Madara's story, including him being resurrected as a God and his goal to save humanity from their suffering and hate that he says they are otherwise destined to be stuck in.
Again, Hashirama is the Judas figure to Madara's Jesus;
Hashirama is his "disciple" who accepted and admired the human representation of the divine at first, but ended up opposing and rejecting the "Savior" figure. Just like Jesus, who faced rejection and hostility from most people but shared a deep bond with his small group of disciples that included Judas, Madara experiences the same rejection and hostility from most people around him but shared a deep bond with Hashirama. The Galatians verse "They hated Jesus because He told them the truth." comes to mind.
Ultimately though, Hashirama/Judas betrays Madara/Jesus by using trickery to cause his human death, thus catalyzing Madara's/Jesus's resurrection, their ascension to godhood, and setting them up for the apocalyptic Judgement Day they are said to bring upon humanity in the future.
