They begin a quest for eve evermore spiritual experiences. They try out religions as if they were shopping for a pair of shoes that have to fit just right. If the shoes begin to feel the least bit uncomfortable, off they go looking for a better fit. The key is to balance apologetics with prayer, worship and the sacraments. Reason and faith need not conflict, indeed, cannot according to St. Thomas Aquinas.
Rational inquiry reinforces our faith rather than weakens it.
Another reason to study apologetics is often overlooked. While men may dominate the clergy, women dominate the congregations - at least in numbers. At the risk of sounding sexist, we must be able to approach faith rationally if we expect to attract western men to our faith. Many women seem more able to accept a supernatural explanation for a life-changing transformation experience than are men. Men aren't as likely to accept and act on subjective accounts of conversion experiences, private revelations and mystical models.
