I’m quite confused about the concept of “faith” generally. Particularly when I’ve heard people say that it doesn’t deal with belief in propositions but an appetitive trust and seeking of God.
…
And how exactly is faith a gift to us from God?
I think when you think of this “appetitive trust and seeking,” and how it relates to voluntary assent to truth (true belief) and keeping troth (being faithful), it would be best to think in terms of God’s action in Creation and Redemption.
God knows the desireable end for each of us, for He has chosen it and takes all steps to perform it; yet he does not do so without our participation, so that we too must be led to desire the good He desires for us, and to cooperate in His work of making us fit for that desireable end. That end has many characteristics, but its essential and definitive characteristic is “friendship with God.”
Friendship, that is, dwelling in charity with God or any person, has three hallmarks: seeking good for another, mutually expecting good from each other, and real sharing in that good (see
newadvent.org/summa/3023.htm II.II.32.1).
But our entry into such a friendship with God is complicated by our sin and by the changeableness in our nature, and so God offers us virtues which lead us to charity, to friendship with Him, called “faith” and “hope.”
As you say, or as the author of Hebrews says, “without faith it is impossible to please God, for whoever comes to God must believe that He is, and that He is a rewarder of those who diligently seek Him.” But notice that “faith” in this sense is not
merely recall of statements, nor even
merely notional assent (“Yes, I can admit this might well be true”). This faith is real assent, assent which interlocks with hope and admits the possibility of friendship with God, so that we expect the good from Him and believe it is possible to be drawn to Him.
Of these, faith is most concerned with recognizing what God has shared, so we do talk most about assenting to reality, believing what both reason and revelation tell us, when we talk about faith. Especially, we talk about “faith” as the ability to build our lives on realities we never would have grasped without revelation, realities essential to friendship with God.
“Hope” has more to do with not only the expectation of good from God, but even the appetite for that good (like when you suddenly discover you’re hungry because a delicious meal has been set before you, the imminent satisfaction strengthening the desire). And “charity” is the whole thing itself, the enjoyment of friendship with God so total that it makes for friendship with all other people, too.
These overlap; it is almost impossible to talk fruitfully about any of the theological virtues without talking of all the others.
Viewed in the order of generation, faith could be said to contain hope in seed form, and faith/hope to contain charity in seed form; but viewed in the order of causation, charity is the full flower and fruit, without which we would not care for the plant at all.
Faith always “involves” hope, and faith/hope always “involves” charity, and trying to have any without the others sterilizes them all.
