My parents grew up in the 40's and 50's and they cannot separate patriotism from Christianity. Growing up in the 70's and 80's myself, I always thought this idea to be strange so I did a bit of research. What I found is that Billy Graham was responsible for demonizing Communism and marrying Christianity with American Nationalism during the 50's. The interesting part is that the message at the time was a strong message - one that most Americans could really buy into, but as time past, many people in my parent's generation stop going to church because, in their minds being a Christian means the same thing as being patriotic - and the best way to be patriotic, according to my parents is to watch FOX news because "they don't focus on what America does wrong all the time, just what we need to do to get back to where we were in the 50's (voting out the liberals)"
So - if we go back farther in history - are there any other leaders that combined patriotism and Christianity as strongly as Billy Graham did in the 50's? Also, is this a positive, negative or not a big deal either way for Christianity?
The greatest revival in recent history was in the latter 60's and early 70's and it had nothing to do with Billy Graham.
It was entirely the work of the Holy Spirit. Thousands of men and women participated and acted as leaders in those days and thousands of religious leaders opposed it.
It is inaccurate and misleading to suppose that Billy Graham was responsible for it.
It was the hand of God. Nothing less.
Billy Graham may indeed have had an effect on your parents, but he had little effect on the rest of the generation.
Your research results are skewed.
My folks grew up about ten years earlier than yours; 1930's - 1940's.
Adolph Hitler and Franklin D. Roosevelt had a severe impact upon my parents generation; Tom Brokaw calls them the Greatest Generation.
Most secular sources as well as living testimony of folks who lived those days bear it out.
The USA was in immense and immediate danger from its enemies. Prayer and religious observance was part of the united effort to combat our enemies.
Historical references also indicate that during the darkest days of Hitler's invasion of Russia, Joseph Stalin allowed a limited amount of prayer to be offered on behalf of the Soviet Union.
When things go sour, men tend to call out to God or mommy or whoever they think can help them.
Religious observance WAS patriotism in that it was as much of a tool for victory as guns and bombs.
I grew up in the 60s and 70s.
The factors that affected my generation was the assassination of John F. Kennedy, Bobby Kennedy and Rev Martin Luther King.
The Viet Nam war was a BIG factor.
Government lies and cover ups about the assassantions, the war and the Nixon Watergate affair ultimately widened a credibility gap between what the government told us and what the American public believed.
The war against Communism was real, but our motives and methods were not.
I personally had the opportunity to spend an evening eating and drinking with Communist guerilla fighters in those days.
They were as much in the dark about our motives as we were.
Soldiers in the front lines are rarely afforded a look at the big picture, which is why our boys fight abroad today.
They know nothing and believe less about our governments' true motives in the middle east.
I also had the opportunity to meet and talk with men who had done God's work in Communist lands and had paid a terrible price for their devotion.
One in particular had suffered much torture at their hands.
This is first hand knowledge, not something I read in a book saw on TV or learned on the internet.
Communists hate Christians and Jews.
Communists kill, torture, and imprison those who do not accept their atheist agenda, including Christians who do nothing more severe than deliver Bibles to their brothers and sisters (I met a Bible smuggler once too - he had a lot of interesting stories to tell) .
There is a good reason why Communists have been vilified.
Their economic system is corrupt, they are immoral and their system is based upon lies and deception.
Those who promote the Communist agenda have believed a lie or are base liars themselves.
