The parishes of The Diocese of Oakland rely on the generosity and stewardship of each of their members. Gifts from the faithful are vital to keeping each church community active and fruitful. Even though they are not able to minister to each of you in person currently, your parish still needs your financial support for ongoing operations and expenses. Please continue to make your gifts during this difficult time.


One option is to sign up for automatic transfers. Click here for more information.

Another is to donate online using a debit or credit card. Click on the "Donate Now" button and this will redirect you to the online support page at the Oakland Diocese website. It is very important that you select the correct parish from the drop down menu to ensure that St. Callistus receives your donation. See image below as reference.


Tithing is an essential part of our Christian faith. During these tough times, if you are able, please consider doing a recurring automated withdrawal to help our St. Callistus church through these times, too. You may cancel automation at any time, afterwards.
