I watched the video and I still think he's more talking about working-class UKIP-style anti-immigrant sentiment (sorry if I've misunderstood what you meant!). He introduces the speech by describing the riot as being about "the usual complaints about strangers - they eat our food, don't speak our language, take our jobs, take our houses, better send them back where they came from." He cuts the religious part of the speech ("What do you, then, rising gainst him that God himself installs, but rise against God? What do you to your souls in doing this?") and leaves in the economic images: pictures the foreigners with "poor luggage" worried about "costs for transportations", the Londoners wanting to "kill them, cut their throats, possess their houses", and "not at all appropriate to your comforts, but chartered unto them".

I mean I think anti-immigrant feeling is nearly always a fun cocktail of racism, religious prejudice and economic anxiety, but there's not an explicitly religious element in the speech as he performs it.
