Last week, Catholics in New Zealand celebrated the Feast of the Assumption, and last week’s episode of 15 Minutes with the Bishop was on that topic. This week, Bishop Patrick talks about holy days of obligation, of which the Assumption is one in New Zealand and in some other countries around the world. How has the number of holy days changed? Is Sunday a holy day of obligation? And what about the idea in the UK of re-instating holy days of obligation?
