I'd strongly suspect that for dramatic purposes there is no miracle spell and no equivalent, just like there's no true resurrections.
Really, the miracle spells seems like a terrible addition to any non-table top story (expect maybe something where the whole story is structured around it like genie short stories). If Rich wants a spell to stop an Earthquake (an example from the miracle's spell description) he'd foreshadow and use a spell that does exactly and only that, without raising any questions about using it to teleport or any random thing.
I really don't see how that's anything other than a break down of "Ain't no rule says you can't kill the ushers".The whole reason The Durk One could kill the ushers was because the meeting was being administrated by a third party, who had no protections. They were elemental worshipers, after all, with no representation in a Godsmoot. Presumably, also not selected by divine choice. A lot of the Moot as we know it seems to be church laws, if useful and well-meaning ones, not divine command.
