[Dialogue] Passover Between Secular<->Religious

I think the author Tanya Luhrmann says in the quoted article:"I have said that I do not presume to know ultimate reality". Curious why she says she doesn't "presume to know ultimate reality" Doesn't know "ultimate reality" in one community but does the other? She feels free to presume in one community not the other? Doesn't feel free to presume in either community? Admire her apparent willingness to "passover" from one life understanding to another and returning to express her experience. Malachi Martin or Done Done talked "passover"?. Can't remember which.
