Anyone out there have a clue what Thin Lizzy mean by their song Holy War?

Lyrics:

A sample:
If you will adore me
Bow before me and praise my name
If you place no god before me
Then all I have is yours to claim
And if God is in the heavens
Why did God let children die
If you don't ask these questions
There is no reasons why
We are chosen
We are one
We are frightened of no one
And no one will win this war
This is the way
This is the law


Holy War performed in concert, 1983. Hat tip Infidel Bloggers Alliance.
