The obligation to attend Mass each week has been lifted/extended until July 31, 2020. Here is an excerpt from the Bishop’s letter.
“The dispensation is granted broadly to ensure that anyone who needs to stay home to protect the common good can do so confidently, in good conscience. But those who are truly able to attend Mass should remember that we are transformed by being joined to Christ in the Eucharist. Only a weighty reason should keep us from being sanctified through participation in and our reception of Christ’s body and blood.”
