"Gluten-free" Hosts: Distributor Information

Parishes have contacted the Office of Worship inquiring about “gluten-free” hosts. While one could purchase “gluten-free” hosts, hosts which have no gluten are considered invalid matter for Mass. In fact, hosts marketed as “gluten-free” that are permissible for use at Mass actually would/will have a trace of gluten. For example, while one distributor names their hosts “gluten free,” there is a trace of gluten, “below 20 parts per million” (
The USCCB has a website dedicated to low-gluten hosts, as well as the information of the four approved distributors of low-gluten hosts. Parishes using “gluten-free” hosts are encouraged to visit the USCCB website, and too, the websites of the four distributors.
If you have any questions, as always, please feel free to contact the Office of Worship.

Frequency Changes to Wireless Sound Systems

This information was supplied to the Office of Worship through the Federation of Diocesan Liturgical Commissions (FDLC):

The FCC will be requiring institutions to vacate the 600 mhz band in wireless sound systems (similar to when the 700 mhz band was phased out in 2010).  Dates for this varies by region, but all will be impacted by 2020.  Here’s an article with more information:  

According to information supplied to the FDLC, 600 MHz is fairly common unless there has been a recent upgrade. Sennheiser and Audio-Technica have rebates running through March 31 for replacement microphones. Sennheiser says they will accept any competitor’s microphone for the exchange rebate. Parishes are advised to contact the local company which installs and/or maintains your system.

If you have any questions, as always, please feel free to contact the Office of Worship.
