Pray for wisdom. IMHO, you seem to have substituted knowledge for wisdom. That’s understandable as you are only 24. You haven’t had time to really experience life yet. Did God call you to the seminary…or did you call yourself? If you have only an academic understanding of this faith, your enthusiasm will indeed fall off. You have to extend yourself beyond what is knowable. I really don’t mean to insult you, but I do perceive a sense of arrogance in your writing. Christ instructed us to come to him as a child…not a scholar. Come to God with humble and contrite heart…not with the security that you’re the smartest guy in the room. Knowledge is a good thing, perhaps a great thing, but it’s only useful if it is used to glorify God…versus satisfying self.
I don’t ascribe to this Kierkegaardian view of the faith. I (and as far as I know the Church, at least Maritain makes a strong argument for it in ‘Aquinas: Angel of the Schools’) is fairly Thomistic in this sense that we cannot ‘turn off’ our reason. Unlike Kierkegaard I do not think that I can believe something that I know to be wrong.
Belief after all is an act of the intellect, not of the will. In fact, many commentators on Aquinas like Banes note that their is very little room for a ‘will’ (squeezed between ‘grace’ and ‘intellect’). This is the reason for the Molina reaction to Thomism’s more Calvinist leanings. And I definitively do not ascribe to the Scotus compromise which opened the way for nominalism and later Lutheranism.
