Until the later 20th C.".. the majority of other Pentecostal denominations, officially opposed Christian participation in war...--wikipedia
I first learned of that about 1980 when I was doing research for my book on Christian Pacifism and read a Masters Thesis on it.
This is the 30th Anniversary of the book and it is now an ebook for Nook and Kindle where you can read some reviews and with the Kindle "Look Inside" feature, you can read my story.

If you are a pacifist, then you cannot engage in violence by proxy either, otherwise you are being hypocritical.
This means that a pacifist cannot call the police when attacked, he has to grin and bear it, take it on the chin as they say!
When someone decides to rape your wife or children, you cannot truly defend them.
Pacifists demand that we turn the other cheek because of what Jesus said.
This being the case, a pacifist cannot claim on his insurance when the house burns down or his car is damaged, because that is not turning the other cheek. His property is being defended by proxy.
The problem with many "christian" doctrines is that they are frequently applied in a partisan manner. If pacifism is true, then the principle must be true in all circumstances.
Again, it is almost impossible for a pacifist to lay down his life for another, without first abandoning his pacifism and making a violent response.
ie. If someone is attacking a woman. What can you do. The famous answer I have seen several times, even here, is that the pacifist would resist by "getting in the way". His aim being to obstruct but not harm the perpetrator. The violent perpetrator therefore just kills him as a nuisance. He has not laid down his life for the victim, - who still gets raped.
All that has happened is that the pacifist has needlessly wasted his life for a banal principle. He has made no sacrifice for the victim whatsoever.
