I had a similar problem at first with the cubscout pack I was part of when I first started, I am also in the Baltimore Area Council, the Catholic church pretty much said we as a pack had to attend mass at least once every 2 months but the non-Catholic boys were not going to be allowed in the service. My grandmother whom was a den mother at the time called BSA HQ in Texas and told them what was going on. BSAHQ told us the church could ask the pack to attend mass but could not willfully stop any boy willing to attend to attend the service. So I got to attend the mass but I did not particate in the service itself like taking commiumon.
P.S. As a side note if you are sort of new to being the Packmaster/Scoutmaster thing be aware the CO does own any pack/troop equipment if the pack/troop would fold or move to another CO and the only way to get around this would be to either sell it or give it away. Equipment includes the flags, pack/troop own equipment such as mess kits, tents, etc. Does not include the pack/troop's money, uniforms, etc.
