It makes sense from a certain perspective:

Angels:
Tumblr: Gentle, nice and friendly people with wings coming from heaven.
Un-tumblrized: Otherworldy lovecraftian beings from beyond that have to announce themselves to humans with the phrase 'don't be afraid' and mask themselves with their wings as their unfathomable, incandescent appareance would blind anybody that gazes directly at them.

Devil:
Tumblr: Dramatic emo badboy that was cast away from heaven because he was misunderstood and too edgy.
Un-tumblrized: The manifestation of all evil, appearing in the Revelation as badass seven-headed, horned dragon that first battles the Archangel Michael in Heaven and then wages war on the entire world.

Jesus:
Tumblr: Friendly ancient hippie that teaches about peace and tolerance.
Un-tumblrized: Divine king of the world and the judge of all souls at the last judgement.

GET ON WITH IT ALREADY!
