In an interview with journalist Peter Seewald published as Salt of the Earth: The Church at the End of the Millenium, Cardinal Joseph Ratzinger explained that the price of serving truth is usually paid out in small coin:
Ratzinger: I don’t deny that there has been development and change in my life, but I hold firmly that it is a development and change within a fundamental identity and that I, precisely in changing, have tried to remain faithful to what I have always had at heart. Here I agree with Cardinal Newman, who says that to live is to change and that the one who was capable of changing has lived much.
Seewald: Every task usually demands a price, especially a task so lofty as service to truth.
Ratzinger: To serve the truth is a great thing and this vocation’s highest purpose. But that is naturally paid out in small coin. That happens in very diverse, very simple and small things, somewhere in the background. The will to truth remains fundamental, but de facto I have to attend to correspondence, read documents, carry on discussions, and so forth.
For me the cost was that I couldn’t do full time what I had envisaged for myself, namely, really contributing my thinking and speaking to the great intellectual conversation of our time, by developing an opus of my own. I had to descend to the little and various things pertaining to factual conflicts and events. I had to leave aside a great part of what would interest me and simply serve and to accept that as my task. And I had to free myself from the idea that I absolutely have to write or read this or that. Instead of that, I had to acknowledge that my task is here.
Seewald: Do you accept your life; are you a happy man?
Ratzinger: Yes, I accept it, because to live against oneself and one’s life would make no sense. And I think that I have been able to do something meaningful after all, in another way than I had foreseen and expected. And I am really thankful for the life God has disposed and shaped.
