Why God alone? If reason (or what i will call the virtue of wisdom) is a preparation for Faith, then is it not also a cause (though
not the only cause) of Faith?
I do not think so. I would call it a necessary predisposition, but a predisposition does not necessarily produce faith. There are so many virtuous heathens, pagans, non Christians, etc who still do not have faith. Why? I believe its a mystery that has to do with the concept of predestination and free will. It is beyond us though.
Consider an example: When my son listens to a song played on the Internet for the first time and then picks up his guitar and plays it perfectly the first time i’m impressed. Now, i might tell you it is his talent alone that makes him so good at playing the guitar. I think you would be right to point out that it is not only his talent, but also his many months of practice playing different but similar songs that have prepared him to play a new song so well the first time he makes the attempt.
Just as talent and preparation are the causes of my son’s musical ability, so too God and wisdom (at least in my own experience) are causes (and possibly not the only causes) of Faith.
Predisposition to receive grace also has its reverse, the predisposition not to receive grace.
Let me use another analogy. If I had been a drug user, or frequented prostitutes, or was taught from an early age that women were just things to be used, it is very unlikely that my wife would ever have found anything attractive in me or worthy to mary. Even so, even if I had all the gifts of virtue, all natural goodness, etc… I could not then say that I deserved my wife’s love. You could say that my virtues predisposed me to receive her love and cherish it for the gift it is, but there is nothing that can allow me to say I have earned her love, or that my virtues or reasoning power caused her love, or caused her to reveal the secrets of her inner life with me. They are gifts, unmerited, and undeserved.
However, God’s love and his ability to penetrate even the most hardened hearts is something that far surpases my human analogy. His truth can tocu anyone he choses, regardless of their predisposition. Although to be honest, I do find such conversions all the more miraculous and wonderful on account of their improbability.
Anyway, all this to say that I don’t think there is a necessary corelation between reason and faith, such as in cause and effect.
Does this make sense?
God bless,
