"I’ll just simply say we haven’t done any apologetics in a concerted fashion since Vatican II. I don’t know why. I’m still trying to figure this out myself—why did apologetics became a bad word, why did it become a reflection of some kind of inauthenticity of faith? We’ve somehow drifted into a Kierkegaardianism—we have to take a leap of faith across an infinite chasm. But I’ve never thought that at all! I luckily had great teachers who believed reason and faith came from the same source, with God never intending us to jump over an infinite chasm."
