Unfortunately there is a lot if truth in this article. The gap of what many Christians say they believe and how they behave can be very wide:

How to explain the Grand Canyon-sized gap between principles outlined in the Gospels and the behavior of believers? Christians typically, and rather lamely, respond that shortcomings of the followers of Jesus are simply evidence of man's inherent sinfulness.
But if one adheres to the principle of Occam's razor — that the simplest explanation is the most likely — there is another, more unsettling conclusion: that many people who call themselves Christian don't really believe, deep down, in the tenets of their faith. In other words, their actions reveal their true beliefs.
That might explain why Roman Catholic bishops leave predator priests in ministry to prey on more unsuspecting children. Or why churches on Sunday mornings are said to be the most segregated places in America. It also would explain why most Catholic women use birth control even though the practice is considered a mortal sin.
Culturally, America is still a Christian nation. The majority of us still attend church at least occasionally, celebrate Christmas and Easter, and pepper our conversations with "God bless you" and "I'll be praying for you."
But judging by the behavior of most Christians, they've become secularists. And the sea of hypocrisy between Christian beliefs and actions is driving Americans away from the institutional church in record numbers.
