Chrism Mass Every year, in the week or so before Easter, the Catholic Church has what is called a “chrism mass” in each diocese in which the bishop blesses the holy oils used in the different sacraments. It is also an occasion for the priests of that diocese to renew the promises of their ordination. We had that chrism mass in Phnom Penh today. Here Bishop Olivier (with the microphone) addresses the people who attended. It was an especially joyous event because it had to be canceled in 2020 and 2021 because of Covid-19.
