‘What is my licence to say what I say?’ You ask and prompt me to answer a question which, I must admit, I’ve never put to myself. I’m not given to self-reflection. I live. Life is its own certainty and justification. But now that you have asked me, I've put the question to myself and so I’ll tell you why I practise theology, what theology I practise, and how.

In what name, in virtue of what? I myself see two decisive elements: on the one hand, my vocation as a friar preacher, which shapes and fills my life; on the other hand, circumstances and appeals. I’ll start with this second element, because it’s easier to explain.

I never had a plan. I’ve tried to respond to appeals, requests, circumstances. Most appeals came from outside, in the shape of requests. I receive them every day, often two or three times a day ... If anything, I’ve accepted too many. That accounts for the quite ridiculous list of my articles, whether long and learned, or brief and popular. They amount to date to some 1630 or 1640 titles! But there are also the interior appeals, inspirations. These can range from the humble enough idea to read this, follow up that reference - yes, that’s how I operate, I think that our lives are shaped even in these tiny ways - right up to the first great appeal, in the years 1928 - 1929, to dedicate myself particularly to the Church and ecumenism. Two things intimately inter-twined. Here I very soon saw what I had to do. It got more complicated as time went on, of course, but the through-line always remained the same. And I have to admit that I was filled to overflowing. I wanted to change something and I saw very clearly what it was. My brethren and friends, my comrades in arms.
