From what I can gather, it's probably the "recording method" the creator of the world uses to keep track of "Important People/Events".

It first starts being mentioned when Rou becomes an Apostle Lord and gains the True Name Yatendouji.

I get the feeling that the people within it have 'specific' Psalms about them, as when it was referring to Rou it had something like Frontier Book of Psalms, but with Avenger it had something else about awakening.

Once the challenge is over I'll try to figure out whether that's the case or not. ^^
