The state (or country) should always stay out of the affairs of the church. The church should be free from any restrictions from the state since the head is Christ This doesn't mean that the church is above the law. The church should obey the law unless the law requires disobedience to God, at which point the church should disobey the law in order to obey God.
Any idea of "Separation of Church and State" should be for the church's protection from the state, otherwise the result will be to "kick God out" of the country so to speak and that is never a good thing!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
