A New Zealand canon lawyer has discussed, in a peer-reviewed book, the Church’s law on the seal of confession, with particular reference to sexual abuse of minors.
Msgr Brendan Daly, judicial vicar for the Tribunal of the Catholic Church in New Zealand, had a paper published in Roman Replies and CLSA Advisory Opinions 2018 (Washington DC: Canon Law Society of America) last year.
Msgr Daly stated in the paper that many issues concerning the seal of confession are misunderstood.
