The only substantial references in there are 'his own family' (a running gag about Lloyd George from the British politics threads) and 'the sun is God', which were the OTL last words of the artist JMW Turner. The rest is mostly extracted from a lunatic on a bus for that authentic flavour.
Oh, when I first read it, I thought it was a reference to the double-meaning sun/son, like in that Star Trek episode when they find this planet with a Roman Empire and this small sect worshiping "the Sun", and Spock being somewhat confused by this because the Terran Roman Empire didn't have any sun-worship cult, only for them to realize that it was the Son, they were referring to, and that the Sun cult was really that planet's version of Christianity.
Then when you told me it had to do with days of the week and Norse gods, I figured it must have been something that Ian McKellen-guy said. Tuesday = Týr, Wednesday = Odin, Thursday = Thor, Friday = Frey, Saturday = Saturn, Sunday = ??? What god is the sun? Oh, the sun is God!
