These findings come from The American Worldview Inventory 2023, conducted by the Cultural Research Centre at Arizona Christian University under the supervision of George Barna, director of research at the Cultural Research Centre. While born-again Christians make up about one-third of all U.S. adults and are considered “the backbone of local church activity because of their higher level of commitment to the Christian faith,” the study shows that between 2020 and 2023, the share of those who say they believe Jesus did not commit sins during his lifetime on Earth fell from 58% to 44%.
Jesus being sinless is central to the hope Christians have in Him as Saviour explains the apologetics website Got Questions because, “If Jesus were not sinless, there would be no sacrifice for sin.” The apostle Peter stated it clearly: ‘He committed no sin, and no deceit was found in His mouth.’ (1 Peter 2:22) Indeed, as Jesus Christ is God, He has no capacity to sin,” the Christian website explains.
This shift in belief among born-again Christians was among six that showed a significant decline in the past three years that Barna characterized as “indefensible.”
Fewer than half of born-again Christians also now believe they have a unique, God-given calling or purpose. The share of those who held that belief fell from 88% to a staggering 46% during the pandemic.
A downward trend was also observed among those who say the Bible is unambiguous in its teaching about abortion. That belief fell from 58% to 44%. Those who say human life is sacred fell from 60% to 48%.
The number of born-again Christians who say God is the basis of all truth fell from 69% to 63% over the period. The share of born-again believers who say they are deeply committed to practicing their religious faith fell from 85% to 50%, while the share of those who say they read or study the Bible at least once a week fell from 60% to 55%. When it comes to the general population of U.S. adults, Barna said the share of the population that claims to hold a biblical worldview fell from 6% to 4% in the last three years, while less than half now claim to be “deeply committed to practicing” their religious faith. That measure fell from 60% to 48%. Barna also found that only 33% of adults now say they attend church service during a typical week which shows “a decline representing the loss of about 15 million churchgoing adults each week.”
The veteran researcher said the findings on the drastic shift in Christian belief over such a short period of time are “highly unusual” because “religious beliefs and behaviors have typically been a hallmark of consistency.” “Most religious beliefs change over the course of generations, not a few years,” Barna said.
Barna noted that a significant driver behind the decline in Christians holding on to a biblical worldview is syncretism, an ideology described as “the worldview that merges otherwise incompatible philosophies of life, particularly evolution and a Cosmos that has existed for billions of years, into a made-to-order worldview that incorporates enough biblical elements to be minimally Christian in nature.”

These statistics highlight how successful Satan’s strategy to undermine the foundations of God’s Word has been. Thankfully God has raised up ministries such as Creation Ministries International (CMI) and Answers in Genesis to show that evolution and its history of billions of years for this Cosmos is not defensible. In fact, the audacious claim by secular scientists in the New Scientist book How Evolution Explains Everything About Life (2017) cannot be substantiated. On page 69 they claim ” The only thing we know for certain is that life must have popped into existence sometime between Earth’s formation 4.5 billion years ago and the appearance of the first undisputed fossils about 3.4 million years ago.” Living cells require information (DNA) and decoding machinery. Even the simplest living cell has an enormous quantity of information on its DNA (about 600,000 letters) and it has the decoding machinery to read these letters. Also, the instructions to build this decoding machinery are encoded on its DNA. DNA can’t be decoded without the machines, but the machines can’t be built without the DNA coding for them. An impossible vicious circle for chemical evolution. There is simply no way “life must have popped into existence“.
