As of today (2020-07-27), "faith-based services, cultural ceremonies, and protests" are _not_ prohibited if they don't exceed 100 people (if indoors) and there are no limits if they are outdoors and a) everyone wears a mask and b) they distance by at least 6 feet:
"On May 25, 2020, in an effort to balance First Amendment interests with public health, the State Public Health Officer created an exception to the prohibition against mass gatherings for faith-based services and cultural ceremonies as well as protests. Those types of gatherings are now permitted indoors so long as they do not exceed 100 attendees or 25% of the capacity of the space in which the gathering is held, whichever is lower. State public health directives now do not prohibit in-person outdoor faith-based services or protests as long as face coverings are worn and physical distancing of 6 feet between persons or groups of persons from different households is maintained at all times. "

In counties that have been on the County Monitoring List for three consecutive days, indoor protests are not currently permitted. State public health directives do not prohibit in-person indoor protests as long as (1) attendance is limited to 25% of the relevant area’s maximum occupancy, as defined by the relevant local permitting authority or other relevant authority, or a maximum of 100 attendees, whichever is lower, (2) physical distancing of 6 feet between persons or groups of persons from different households is maintained at all times, and (3) singing and chanting activities are discontinued."
