The priests have been told they can not even volunteer their services of giving the sacraments. (without pay).Priests have died for less. Of course that usually happens in a totalitarian country, not the United States of America.
1) Priests employed by the government cannot trespass on military bases during the shutdown, and therefore may not perform services on the base. <-- I understand why the gov't would say this.
2) Priests cannot go to a neutral place and act as priests <-- totally indefensible and unAmerican.
