In 2009, Al Mohler warned about the increasing tendency of evangelicals to abrogate the historic doctrine of Hell. He wrote,

“The traditional doctrine of hell now bears the mark of odium theologium—a doctrine retained only by the most stalwart defenders of conservative theology, Catholic and Protestant. Its defenders are seemingly few. The doctrine is routinely dismissed as an embarrassing artifact from an ancient age—a reminder of Christianity’s rejected worldview. The sudden disappearance of hell amounts to a theological mystery of sorts. How did a doctrine so centrally enshrined in the system of theology suffer such a wholesale abandonment?

The answer to this mystery reveals much about the fate of Christianity in the modern world and warns of greater theological compromises on the horizon, for, as the church has continually been reminded, no doctrine stands alone. Each doctrine is embedded in a system of theological conviction and expression. Take out the doctrine of hell, and the entire shape of Christian theology is inevitably altered.” (Emphasis is mine) – Al Mohler, Hell Under Fire: Modern Scholarship Reinvents Eternal Punishment

When we cherry-pick doctrine and arbitrarily reject a historic Biblical doctrine, or modify it to suit our personal taste, we inject a fatal flaw into our faith. Irreducible complexity is the argument that some systems with multiple interacting parts cannot function if one of the parts were removed. Irreducible complexity is a good way to understand the statement that no doctrine of the faith stands alone. It’s also a good way to understand Christianity. Remove any historic Biblical doctrine and your faith is fatally impacted.

By way of illustration, we cannot separate the wrath and justice of God from his love. The crucifixion was a majestic and awe-inspiring demonstration of God’s love. But it was also simultaneously a terrifying demonstration of his wrath and justice. Remove his wrath and you end up with a benevolent, doting grandfather-like concept of God. All of God’s attributes operate simultaneously with every divine action . . . with “irreducible complexity.”

No doctrine stands alone.
