It is not just scholars and ministers who will benefit form training in philosophy, but also laypeople who need to be intellectually engaged if our culture is to be effectively reformed. Our churches are unfortunately overlying populated with people whose minds as Christians, are going to waste...they may be spiritually regenerate, but their minds have not been converted; they still think like nonbelievers. Despite their Christian commitment, they remain largely empty selves. What is an empty self? An empty self is a person who is passive, sensate, busy and hurried, incapable of developing an interior life. Such a person is inordinately individualistic, infantile and narcissistic...if wee as the church are to engender a current of reform throughout the culture, then we need laypeople who are intellectually engaged with their faith and take their Christian identity to be definitive for their self-conception.
