I don’t know, I went to a friend to his Catholic mass on Christmas day. The church had two masses going at all times and several times throughout the day. It was full to the last seat.
We didn’t have two Masses going on at the same time, but we had parishioners packing the Church, the RCIA and the overflow going to the parish hall. The RCIA room, parish hall and vestibule all have video and audio hookups.
Totally amazing.
