The precept of the Church to attend Mass on Sunday is not intended to risk one's life or health.
The predicted temperature at leaving-for-church time tomorrow morning will be minus11F. That's thermometer temp, not wind chill. It's supposed to be windy, also. So, if you do not have reliable heated transportation door to door to church tomorrow, STAY HOME!
Instead, set your alarm clock and at 8 am tune in Mass from the Cathedral, with our archbishop +Timothy preaching. North of the city, tune in 100.1 FM, in the city 920 AM, south of the city 1550 AM. Mass on the radio is so much less than actually being there, but it is such a blessing when one just can't get there.
