By sending a message through an oracle, rather than directly communicating through the residual divine favor in oneself, one is announcing to the followers of the Church of the God of Literature and Knowledge that they are under His protection!
From the beginning, the decision to collaborate with the Church of the God of Literature was actually a fallback plan for Kael.
Had the negotiations with the Charles family fallen through back then, and had he not been able to secure asylum from the Scroll Mage Academy, he would have decisively leveraged the advantage he held as a player, even if it meant giving up his own influence, to get protection from the deity.
Kael had never expected his own affairs to go so smoothly, rendering his prepared backup plan completely unnecessary.
