In general, however, my biggest regret is how these events and their venues almost make authentic liturgy impossible, and yet, given their high status and profile, serve as a model for parishes. There was lasting damage from WYD in John Paul II’s time, and this event too might encourage exactly the opposite push from where we need to be going (away from pop entertainment styles and toward authentic and integral presentations of the received forms).
Thank you to PrayTell for the link to the World Youth Day booklet. From what I’ve seen so far, if you are expecting the best of Catholic liturgy, you will be disappointed and maybe alarmed. If you are expecting the worst, you will be pleased at how much of the traditional forms have been retained.
