The True Buddha, Nichiren Daishonin vs True Buddha Nichiren Daishonin

Are you asking if they're interchangeable? They're not.

Thanks, InfraBlue.

Why are they not interchangeable?

The Buddha in each sentence refers to the same Buddha, as our believers see it this way.

"The True Buddha, Nichiren Daishonin," implies that there is one true Buddha whose name is Nichiren Daishonin, whereas "true Buddha Nichiren Daishonin," implies that Nichiren Daishonin is one true Buddha. It leaves open the possibility that there are several true Buddhas.

But it's poor grammar. Are you saying his first name is True; his middle name is Buddha?
