1. I'll leave it to your imagination as to whether I'm walking around my holler, busting meth labs, making investigations and running a police light on my POV like Barney Fife. I DO enforce Fire Laws/Regulations and I do enforce Medical Practice regulations, and when there is a medical emergency myself, or other EMS personnel/FF are the head-honchos of Incident Command for the duration of the incident and can direct LEO to enforce emergency actions. We outrank LEO in that circumstance just as LEO outrank us in Incident Command during active Threat Incidents. As a Volunteer Fire Dept made up of citizens and founded by a bunch of citizens you could say that my Dept is a bunch of "vigilantes", blessed by the Civil Gov't, by your definition.
2. God gave us 3 Governments with specific responsibilities and minimal overlap.
- Family government where the father is the head
- Church government where the Pastor/Elder/Reverend is the head
- Civil Government where the head of state is the head (Mayor, County Commissioner, Governor, President).
In situations where 1 Government has failed/is failing, it is up to the other 2 governments to fill the void as best they can until the missing government is restored.
- If your neighbor's house is on fire and you and your neighbors choose to start a bucket brigade out of the creek until the Fire Dept arrives then you (the family government) are filling in the temporary void of Civil Government.
- A Civil Government-run Orphanage is filling in for the Family Gov't when the parents are missing
- A Church-run Orphanage is filling in for the Family Gov't when the parents are missing
- And if a Church chooses to protect a Christian Medical Clinic when the Civil Government is refusing to do so adequately then you are filling in the void left by Civil Government.
What is NOT Biblical is using the Family or Church government to act contrary to the law OR for the Church or Family Government to
compete with Civil Authority in the realm of Civil Government (think Dark Ages Papacy (Church Gov't), or the Mafia (Family Gov't)).
Likewise it's NOT Biblical for the Civil Government to
compete in the realm of Family Government (Mandated Covid Vax) or in Church Government (Civil Mandates to close Churches).
