While the United States remains shaped by Christianity, the faith’s influence—particularly as a force in American politics and culture—is slowly waning. An increasing number of religiously unaffiliated, a steady drop in church attendance, the recent Supreme Court decision on same-sex marriage, and the growing tension over religious freedoms all point to a larger secularizing trend sweeping across the nation.
But how do the numbers stack up? Is America, home to the largest Christian population in the world, actually becoming a “post-Christian” nation? Currently, 78% of Americans describe themselves as “Christian,” but in order to dig deeper than just self-affiliation, Barna Group looked at a variety of key faith indicators for both belief and practice.
To measure a person’s level of irreligion, Barna Group tracks 15 metrics related to faith (you can find the full list of 15 at the end of the article). These factors speak to the lack of Christian identity, belief and practice. These factors include whether individuals identify as atheist, have never made a commitment to Jesus, have not attended church in the last year, or have not read the Bible in the last week.
These kinds of questions—compared to ticking the “Christian” box in a census—get beyond how people loosely identify themselves (affiliation), and get to the core of what people actually believe and how they behave as a result of their belief (practice). These indicators give a much more accurate picture of belief in America.
Where Are We as a Nation?
Whether one believes this decline of “Christian America” calls for a time of lament, or presents great opportunity (or both) for the church, one cannot help but accept the changing landscape. In just two years, the percentage of Americans who qualify as “post-Christian” rose by 7 percentage points, from 37% in 2013 to 44% in 2015. Across the United States, cities in every state are becoming more post-Christian—some at a faster rate than others
Post-Christian Metrics
To qualify as “post-Christian,” individuals had to meet 60% or more of the following factors (nine or more). “Highly post-Christian” individuals meet 80% or more of the factors (12 or more of these 15 criteria).
1. Do not believe in God
2. Identify as atheist or agnostic
3. Disagree that faith is important in their lives
4. Have not prayed to God (in the last year)
5. Have never made a commitment to Jesus
6. Disagree the Bible is accurate
7. Have not donated money to a church (in the last year)
8. Have not attended a Christian church (in the last year)
9. Agree that Jesus committed sins
10. Do not feel a responsibility to “share their faith”
11. Have not read the Bible (in the last week)
12. Have not volunteered at church (in the last week)
13. Have not attended Sunday school (in the last week)
14. Have not attended religious small group (in the last week)
15. Do not participate in a house church (in the last year)
Christians, let’s get to work!
