Step by Step does what it proposes to do: the booklet takes the reader through terms, legislation and processes of the period in the Church known as the interregnum and the subsequent papal election. Burns attempts to be exact in what is expected of the cardinals fulfilling their key work as a cardinal of the Holy Roman Church. Historians will like this brief booklet for its mentioning of key historical facts of the conclave.
Monsignor Burns, a priest of the Diocese of Paisely, has worked for the Holy See in the Vatican Secret Archives for more than 35 years; he taught for 25 years at the Pontifical Ecclesiastical Academy. Since 2012, Burns has been a Canon of Saint Peter’s Basilica.
Here is an audio introduction with Monsignor Burns produced by Vatican Radio.
