as I conceive every revelation must be let it be communicated how it will

[birdeen's call]

Hi, I'm having a hard time understanding the following sentence from A Series of Letters in Defence of Divine Revelation by Hosea Ballou (1820).

I meant nothing more by the miracles of Mahomet than his pretended 'correspondence with the angel Gabriel,' which I considered, if true, miraculous; as I conceive every revelation must be let it be communicated how it will.

The context may be found here (the sentence is on page 84).

I can't make sense of it. Is a comma missing somewhere?

 

[Tdol]

let it be communicated how it will = no matter how it's communicated

 

[birdeen's call]

let it be communicated how it will = no matter how it's communicated

Oh, right. Thank you, it's clear now. Shouldn't there be a comma before "let"?

It would certainly assist in understanding!
But maybe people read with different assumptions in 1820.
