Extensive interview of the author - auxiliary bishop of Los Angeles since 2015 - with John L. Allen Jr., editor of Crux magazine, which deals with issues of the Vatican and the Catholic Church. Msgr. Robert Barron, for his part is the founder of Word on Fire Catholic Ministries and probably one of the best-known communicators in the United States on doctrinal issues regarding the Catholic faith. This book, of remarkable apologetic vigor, skillfully resolves some difficulties against the Catholic Church, which usually appear in the American media. The author, in the first interview he was given after his election to the episcopate, did not hesitate to point out that the greatest problem facing the Church today is the massive abandonment of our people. The great majority of the people we baptize, confirm and catechize do not remain in the Church (...) Our main concern should be to re-engage with Catholics who have left. These pages are the loyal and optimistic response that the bishop himself offers to the reader.
