Blessed Michael McGivney
- Funeral Mass permitted
- Ritual Mass permitted
- Bl. Michael McGivney is not inscribed on our diocesan liturgical calendar and therefore may not be commemorated in most liturgies. However, in accordance with liturgical directives shared by the Knights of Columbus, Bishop Boyea permits gatherings of Knights to celebrate a votive Mass in honor of their founder on this day and on other liturgical days without an obligatory observance.
