So assuming Farrer’s model, supernatural acts are performed by natural agents, above what they “naturally” are capable of. But they remain acts done by these finite agents. There is dual agency; the divine does not “overwhelm” the human actor

So revelation, for example, may be only possible by this dual agency but it comes into being in the world as an act of agents in accordance with secondary causation

This is why liberal critical methods are perfectly legitimate to test doctrines, because there is no point in the event of revelation/supernatural grace where you can say “here it is. This is the grace part.” It’s a finite act just as much as an infinite act

We can only say something is revelatory by what it makes possible. We can’t behold grace qua grace. “No one has seen God at any time”
