The wire connects to the lightning rod located on the highest elevation of the church. If the church takes a hit from lightning, the wire makes for an easy low resistance path to ground with minimal damage to the building structure.
The copper wire is the ground wire and should be connected to the ground screw on the light fixture mounting bracket or to the ground wire in the ceiling box if present. Make sure to turn off the power at the breaker before working on the wiring.
For a 200 amp service panel to the water meter, it is recommended to use a 4 AWG copper wire or 2 AWG aluminum wire as the ground wire. This will provide sufficient grounding capacity for the service panel and meet code requirements. Be sure to check local electrical codes for specific requirements in your area.

The green wire from the light fixture should be attached to the ground wire in the electrical box to provide grounding for safety purposes. This helps prevent electrical shocks and protects against electrical malfunctions.
The size of the ground wire for a circuit is typically based on the size of the circuit breaker protecting that circuit. For a 200 amp circuit breaker, the recommended ground wire size is 4/0 AWG (American Wire Gauge) copper wire. This wire size helps ensure that the ground wire can safely carry any fault currents that may occur in the electrical system.
Yes, if it is not an insulated wire. If it is bare copper it is always ground. But the hot and neutral wire are also copper, they are just insulated.
If you mean a bare copper wire, that is the "ground" wire.
Black wire to copper screw, white wire to silver screw, bare copper ground wire to green ground screw.

In the USA we call it the ground. If there is a cross in the wires from hot to common the ground or earth wire will give the electricity an easier path to the ground instead of going through a live person. The earth is attached in the main box to a copper rod hammered into the ground. This makes it easier for electricity to get to the ground.
Ground is sized based on the size of the feeder wire and not the amps of the service! However, for a 600 amp service 1500MCM copper wire is one option (NEC 310.16) ;therefor, ground wire is 3/O copper (NEC 250.66) or another option is a two sets of 350 MCM copper wire then a #2 copper (since the biggest feeder wire is 350MCM).
Not always. You could have a conduit with 10 pairs of 14 gauge wire - not every wire in that bundle are going to be ground. Ground is usually identified as having a green coating on the wire ... sometimes it is just bare copper strands or a solid copper wire.
