As of this weekend, the Archdiocese is permitting vaccinated parishioners attending Mass to forego the wearing of a mask in church. However, if you have been vaccinated, you must present to one of the greeters either the card you received after your final vaccination or the record on your phone indicating that you are fully vaccinated. Please have that proof of vaccination ready when you enter church to ensure that others entering behind you won’t be delayed too much.
If you are not fully vaccinated, you will still need to wear a mask in church until Phase 5 is reached in Illinois, presumably about a month from now.
