Yes — there is an important distinction here between
what the Greek says,
how English normally expresses it, and
the convention governing italics in English Bible translations.
1. You are correct about the Greek verb
The Greek verb is
πιστεύω (pisteuō).
It is a
verb, whereas:
- πίστις (pistis) = faith, faithfulness
- πιστεύω (pisteuō) = have faith, trust, believe
- ἄπιστος (apistos) = faithless, unbelieving
- ἀπιστέω (apisteō) = disbelieve, be unfaithful, refuse to believe
So there isn't a separate Greek verb corresponding exactly to the English concept
"believe" as opposed to
"have faith."
And your point about
pisteuō being an action is significant. For example:
It describes someone
exercising πίστις toward something/someone, rather than a merely neutral mental opinion.
But I would make one correction to your formulation:
ἀπιστέω does not simply mean "faithing away." It means
not believing, disbelieving, refusing to believe, being unfaithful depending upon context. The opposite of πιστεύω isn't necessarily a technical "reverse-direction faith."
2. Why don't English Bibles put "believe" in italics?
Because
italic type in older English Bibles does not mean "this English word has no Greek equivalent."
That's the key point.
The italics traditionally used by translations such as the KJV generally indicate
words supplied in English to make the sentence grammatically intelligible, where the translators believed the sense was implicit in the original.
For example, in the KJV:
Some words are supplied to make the English readable.
But
believe is not treated as a supplied word because the translators regarded
πιστεύω as having an established English equivalent:
believe.
In other words, the translators weren't thinking:
They were thinking:
So
believe was considered a translation of the Greek verb, not an addition to the Greek text.
3. And this is where your observation about English becomes interesting
You are right that modern English doesn't normally use
faith as a verb.
We say:
rather than:
But that doesn't mean English has no way of translating the verbal concept of πιστεύω.
Believe is precisely the English verb traditionally used.
The problem is that
believe has changed in meaning and range in modern English.
Today someone can say:
That can mean merely:
But πιστεύω can carry considerably more than intellectual assent, especially when it takes a
person as its object.
For example:
John repeatedly uses πιστεύω with
εἰς ("into"), which gives the expression a stronger relational/directional character than our ordinary modern use of "believe."
4. There is another important point: "faith" and "believe" are not two different Greek concepts
This is where I think your argument is strongest.
Consider:
πίστις → faith
πιστεύω → believe
They are related words from the same Greek word-family.
The English translation makes them look more different than they actually are.
For example:
and
The Greek reader sees the relationship between
πίστις and
πιστεύω immediately.
The English reader sees:
faith ←→
believe
and may assume they are conceptually different things.
They aren't unrelated concepts. They are
noun and verb forms within the same lexical family.
5. But I would not say that "believe" should therefore be italicized
This is the distinction I'd make.
If the question is:
No. It is a Greek verb whose semantic range includes believing, trusting, having faith, relying upon, etc.
If the question is:
No.
πιστεύω is actually in the Greek text.
If the question is:
Absolutely.
If the question is:
It could make the relationship clearer in some passages, but it would produce very unnatural English because
faith is ordinarily a noun in English.
6. One particularly revealing example
Look at John 3:16:
Literally, we have something like:
English cannot naturally say that.
So the translator has to choose an English verb.
"Everyone believing in him" is therefore not an
addition to the Greek. It is the translator's English representation of the Greek
πιστεύων.
And this is why the italics question is important:
The italic convention concerns supplied English words, not whether the English word perfectly reproduces every aspect of the Greek word's semantic range.
The deeper issue
I think your underlying concern is actually more important than the italics.
If we translate
πιστεύω consistently as merely
"believe", modern readers can unconsciously reduce it to:
But the NT usage can involve
trust, reliance, commitment, and personal confidence in Christ, depending on context.
So rather than saying:
I think the stronger linguistic argument is:
And that distinction becomes especially important when we examine
πιστεύω εἰς,
πίστις,
ἀπιστέω, and passages concerning salvation.
If you want, we can take
every occurrence of πιστεύω in the NT concerning salvation and examine what the Greek actually says without allowing the English words
believe/belief/faith to predetermine the interpretation.
