I don't tend to comment on the theological aspects much, even in my Heresies...
However what Stanley says does fit with a reply I made to someone asking about "our" "language" and "mythology"existing in Narnia. In it I suggested that the "music" sung by Aslan at the start, was influenced by the presence of those who were "outside" the music when it started.
Stanleys suggestion would be a reinforcement of my Heresy
