what about ideas such as “we need to rely on God more” or “look to God for help”? If we have everything we need in ourselves, what role does God play?
I think that these notions go beyond what Feuerbach was intending to say (or what the Catholic Church asserts). We’re
not saying that God is merely the Deist Watchmaker, who sets things in motion and then leaves us to our own devices. Rather, we say that God gives us the grace that we need, and this grace helps us (specifically, to perform acts of supernatural virtue).
So, I don’t think that you can draw a simple direct line from what you’re seeing in Feuerbach’s theories of the grounds of religion to practical considerations of how Christians live their daily lives.
If you
did want to draw that direct line, however, extrapolating from Feuerbach, I think you would say something like this: our collective nature is the grounds for who we are and how we act; so, our individual, physical actions are merely the ways in which the “individuals who are not who we really are” interact with other individuals (who are not who they really are) in physical, experiential modes, such that we can distinguish these “not-I” forms in sensory ways. Of course, these experiences all proceed from the single “who I really am”, which is really just the collective human nature. So, the “Us-nature” enables the “me-actor” to act.
Does that help? (It’s kinda weird to write it out like that, for a variety of reasons, not the least of which is the fact that Feuerbach kinda did what appears to be a bit of a 180 in his thought, in his later writings).
He wouldn’t have asserted that “God is the sole cause for our continual existence”, I don’t think, since he would have asserted that what we call ‘God’ really
is our own, shared existence.
From a Catholic perspective, however, things are very different. God is not only who creates us, but He also sustains our existence continuously. He is also the source of the graces which we receive that buoy us up. (In a purely analogous way, our parents (in the ideal case) are there to buoy us up, and sometimes we even rely on them to do so in a very obvious and literal way!)
I just re-read through some of my highlighted passages of The Essence of Christianity a couple days ag
Keep in mind that Feuerbach’s later ideas can appear somewhat contradictory to what he wrote earlier in
Essence…!
