I'm pretty sure Medugnatos said he had got the Prophet's blessing in person before he called the crusade, and the Prophet explicitly mentioned this when he said to the full members "I do not give my blessing lightly".
Yes, he did indeed say that he doesn't give his blessings lightly. But you won't find a letter from Mathurin actually *giving* his blessing to the Crusade. If he actually did so, then it was via private letter to some very small audience, that didn't include the Elders.
It's pretty hard to gauge theocratic opinion when the majority of active Church members are not theocrats.
Sadly, this is true.
