So, I actually did the equivalent of that Fruit of Knowledge move just today, but with Indulgence instead, to a) block an avenue of attack I'd left open, b) get the three coins, and c) clear the last follower off the temple my messiah was on, to get two more followers the next turn! [I would've done it on my own turn, but there was no loss incurred by doing it reactively, and it kept my options open in case I needed to respond to a radically different enemy positioning or miracle.]
I've also been having fun with using Edict to pull last-second flanks, and to threaten/capture an ill-defended enemy temple that my low units were until that moment five tiles away from (two tiles of movement on enemy turn, then two tiles on my own turn, putting me adjacent).
