September 2020:
Sunday Mass Obligation

The Mass schedule for the time being will be as follows:

What about refraining from attending Mass if you are still concerned about the virus?  Those who are at-risk because of age or underlying illness are encouraged to remain at home.  In other words, Bishop Callahan has continued to grant a dispensation from the obligation to attend Sunday Mass.  If you choose not to come to the Sunday Mass for the time being, the dispensation given by the Bishop removes the penalty of sin.  However, we must still keep holy the Lord’s Day (the Third Commandment).  If you choose not to attend the Sunday Mass, please watch a televised Mass or one that is live-streamed.  Sunday is also a good day to spend time in extra prayer and perhaps some spiritual reading – like reading from the Bible.

Please follow the guidelines provided by Wisconsin Department of Health Services:
