I first "met" Bo Reicke through his writings. I had considered asking him if I could become one of his doctoral students in Basel. But first I wanted to become familiar with him. And there is no better way to do that than through reading someone's writings.
You say, "My prospective Doctor Father hasn't written all that much." Then you don't want to study with him. Scholarship means publishing. And Reicke's introduction to the New Testament era is a superb example of that. Biased am I? You bet I am. The man's balance between humanitas and pietas was exemplary. He is now with the Lord, but his influence will live on in my life forever. Thanks be to God.
