A State Religion?

It seems hard to ignore the irony at Destiny Church storming meeting the Waitangi Marae to demand the Government enforce Christianity as the state religion today. The meeting at Waitangi of course was to support religious diversity. I'm sorry but if Destiny Church acknowledge the Treaty as our founding document then they must either accept the (unwritten) 4th article that established religious freedom OR recognise that religion isn't mentioned in the other 3 articles at all. You could argue that "taonga" might include religion, but in 1840 Christianity was hardly the dominant religion amongst all Maori and since the majority of Pakeha (in Kororareka especially) were hardly the most God fearing of people.
