It's exclusive to christianism. Angelic entities without names, most being souls that never saw life, and as such are completely innocent, reason for which they are allowed to become angels.

They are part of the christian doctrine of The Father, The Son, and The Holy Spirit. Alas, they are only present in Christianism. I don't remember there being any equivalent of them in other mythologies.
