What Is Faith, Really? Why the Greek Word Pistis Changes Everything
Description
A deep dive into the gospel, allegiance, and why understanding one Greek word resolves some of the New Testament’s most perplexing tensions.
Most of us think we know what faith is. You believe something. Maybe you trust it. It happens in your head, it’s invisible, and according to a lot of modern Christianity, that’s basically the whole thing — have the right belief in the right moment, and you’re in. But what if the word we translate as “faith” in the New Testament carries a far richer, more demanding, and ultimately more liberating meaning than that?
This post is inspired by two scholars who have done substantial work on this question: Matthew Bates, author of Salvation by Allegiance Alone and Gospel Allegiance, and Scot McKnight, author of The King Jesus Gospel. Their thesis — and I think it’s compelling — is that we’ve fundamentally misunderstood both what the gospel is and what faith means. And getting both of those things wrong has enormous consequences for how we live as Christians.
First Things First: What Is the Gospel?
Before we can talk about faith as a response to the gospel, we have to be clear on what the gospel actually is. Because there’s a good chance your picture of it is incomplete.
Both Bates and McKnight argue — and I think the early church would agree — that the gospel is the objective facts concerning the entire career of Jesus as Messiah. That includes:
* His pre-existence (he was with God in the beginning)
* His incarnation
* His death for sins
* His burial
* His resurrection
* His post-resurrection appearances
* His enthronement at the right hand of the Father
* The sending of the Holy Spirit
* His future return
This is why the four books are called Gospels — Matthew, Mark, Luke, and John — the whole story matters. Paul lays this out explicitly in 1 Corinthians 15:3-8:
“For I delivered to you as of first importance what I also received, that Christ died for our sins according to the Scriptures, and that He was buried, and that He was raised on the third day according to the Scriptures, and that He appeared to Cephas, then to the twelve. After that He appeared to more than five hundred brethren at one time, most of whom remain until now, but some have fallen asleep; then He appeared to James, then to all the apostles; and last of all, as to one untimely born, He appeared to me also.”
And in Romans 1:1-4:
“Paul, a bond-servant of Christ Jesus, called as an apostle, set apart for the gospel of God, which He promised beforehand through His prophets in the holy Scriptures, concerning His Son, who was born of a descendant of David according to the flesh, who was declared the Son of God with power by the resurrection from the dead, according to the Spirit of holiness, Jesus Christ our Lord.”
The gospel, in this framing, is the story of how Jesus became the Christ — the Anointed One, the Messiah, the King. If you think about it from the perspective of a first-century Jew, the whole point was convincing them that this man, Jesus, is the promised King. That’s why Matthew’s Gospel opens with a genealogy tracing Jesus back to David. It’s legal evidence for the throne. You’re not just announcing a theology — you’re announcing a coronation.
Yes, “he died for our sins” is in there. But notice what Paul does and doesn’t say in 1 Corinthians 15. He says Jesus died for our sins. He does not explain the mechanism of how that death accomplishes forgiveness — no atonement theory is named. What he does do is spend considerable time establishing the resurrection, the appearances, and the reality of the risen Christ. The death is one part of a larger royal story.
