WELCOME FRIENDS! The Sunday Mass Obligation was restored in the Archdiocese of Boston on June 20, 2021.

As of March 3, 2022, masks are no longer required at Mass for vaccinated or unvaccinated persons.

To accommodate our high risk / immunocompromised parishioners, we offer a ‘masks required area’ of the church, with social distancing, in both transept wings.


For the benefit of our elderly, sick, and homebound parishioners, St. Mary's is for the time being continuing to live-cast our 11:30 AM Mass every Sunday at: https://www.facebook.com/SaintMarysChurchHollistonLive/.
You do not need a Facebook account to access this page.


You may also watch St. Mary’s Sunday, 11:30 AM Mass live on Holliston Cable Access: Verizon Fios Ch. 33 or Comcast Xfinity Ch. 96.

It is rebroadcast at 4 PM and 8 PM the same day. May God keep you and yours physically healthy and spiritually safe.
