The following was on a handout I picked up at the Center for Barth Studies at Princeton this past summer. Unfortunately, there is no source included. Enjoy!
Student: What one thing, sir, would you tell a young pastor today if you were asked, is necessary in this day and age to pastor a Church?
Karl Barth: Ah, so big a question! That is the whole question of theology, you see! I should say, I hope that during your studies you have visited yourself earnestly with the message of the Old Testament and of the New Testament. And not only of this message but also of the Object and Subject of this message. And I would ask you, are you trained to visit not only yourself now, but a congregation with what you have learned out of the Bible and of church history and dogmatics and so on? Having to say something, having to say that thing. And then the other question: Are you willing now to deal with humanity as it is? Humanity in this twentieth century with all its passions, sufferings, errors, and so on? Do you like them, these people? Not only the good Christians, but do you like people as they are? People in their weakness? Do you like them, do you love them? And are you willing to tell them the message that God is not against them, but for them? That’s the one real thing in pastoral service and that is the question for you. If you go into ministry to do that work, pray earnestly. You’ll do difficult work but beautiful work.
But if I had to begin anew for myself as a young pastor, I would tell myself every morning, well, here I am; a very poor creature, but by God’s grace I have heard something. I will need forgiveness of my sins everyday. And I will pray, God, that you will give me the light, this light shining in the Bible and this light shining into the world in which humanity is living today. And then do my duty.
