to MrMacSon,
What is the likelihood of that? -ie. -

a. What is the probability that James was alive when Josephus was in Jerusalem? - Josephus would have been 15 yrs of age in 62 AD/CE

b. What is the probability Josephus would have known about James, if James was alive in Jerusalem, say, 60-62 AD/CE?
No, Josephus was 25 years old in 62 AD. Probabilty: 100%

Josephus might have known about James only during his trial, if it was not before when James was the leader of a sectarian group.
That was a big affair in Jerusalem, with the involvement of the Sanhedrin, an appeal to the new governor on his way to Palestine and a removal of a new high priest. Something to talk about, including about James being the blood brother of Jesus called Christ. I gave 80% of probability of that point, the rest (20%) being mostly for the possibility of interpolation.
For Tacitus ... he may have learned about 'Christus under Pilate' from Christians or ex-Christians (after the gospels were known)*, (rather than learning (& remembering) it before 71 AD when he was 14 years old or younger (but more than 7 years old)).
* What is the likelihood of that? - ie. the probability of that?
I gave most of 70% for the first option (the rest being for interpolation) and only 30% for the second option.

Cordially, Bernard

Okay just to spell it out:

P("The phrase 'Descendant of Abraham (Gal 3:16)' is not IID") = 72%?

(I am not trying to throw away the part about: "therefore implying the historicity of Jesus", however, I think it is difficult to include in the above probability and more naturally accounted for elsewhere. If this is not what you have in mind, we must begin to agree on the exact formulation).
If it is okay for you perhaps we can pretend the probabilities are all the same for all 15 points and focus on the details later?

Finally, the probability we are trying to compute at the end of the day is that Jesus existed correct?
Well, I do not know what exactly about what you have in mind, but just proceed as you please.
Sure, simplify to 72%. But if you decide "Descendant of Abraham" does not necessarily imply the historicity of Jesus, then I can see more arguing: because in this case, the 72% (which then would mean only that the phrase was original and therefore not including "interpretation") should be increased. Because I included all IID in the 28%. If "interpretation" is taking out, the 72% becomes higher. I think the simplest thing is to include all the IDD in a bundle.
For example, if you think there is a chance of 10% "Descendant of Abraham" does not imply historicity. Then I would say, the 72% should be raised to 82% because the "Interpretation" has been taken out from the IID for that phrase.
Then, if "dependance" as being null is not contested, the overall result will be 0.82 * 0.90 = 72% back from where we started.

Cordially, Bernard

Yes, I was wrong: I had thought/assumed Josephus was born in 47 AD, without looking it up
  • (and I should have thought more & deduced he would have been in his 20s in the 60s before posting).
I assume "Probability: 100%" refers to Josephus's age being 25 yrs of age in 62 AD -ie. P(Josephus born 37 AD) = 100%.
  • (Can we be so sure that Josephus was born 37 AD? - maybe 95% confident?)

There are a few things to look at and work out here, Bernard, as with a lot of the information you are trying to look at or use.

What is the probability that the James killed in the 60s in Jerusalem, in the accounts of Clement, Hegesippus, and Josephus, are all the same James?

What is the probability that Josephus, as a Jewish military leader, would have come in to contact with a James the leader of a sectarian group?

What is the probability that, if Josephus knew such a sectarian-leader James, he was the one whose death was described by a/ Josephus himself, or either b/ Clement, or c/ Hegesippus, or d/ 2 or 3 of those authors?


Separately, what is the Probability that there was a James who was the blood brother of Jesus?

Which James in the Synoptics might he have been?

What is the Probability each of the James in the Synoptics was Jesus blood brother?

Was the same James in Gal 1:19 the same James as in Gal 2? What is the Probability they are the same?

Which James was in 1 Corinthians 15:4-8? (NRSV)
  • 4 ..he was buried, and that he was raised on the third day in accordance with the scriptures, 5 and that he appeared to Cephas, then to the twelve. 6 Then he appeared to more than five hundred brothers [and sisters] at one time, most of whom are still alive, though some have died/fallen asleep. 7 Then he appeared to James, then to all the apostles. 8 Last of all, as to one untimely born, he appeared also to me.

    What is the probability that that James was the same as the other James?
Separately, again, What is the probability that a James became the leader of the early church? ahead of Peter?
  • What is the probability that James was Jesus biological brother?
I think you have to look at each question, and determine a Probability for each one to try to put things in perspective.

Ah. I think I understand what you mean: Your saying that if Gal. 3:16 is not IID, that means it is not an interpretation (one of the I's), that means Jesus was literally a 'descendant of Abraham' (i.e.: thought to be), that means Jesus was actually thought to have existed on earth (because Abraham did), that means Jesus was historical because certainly, that is the most reasonable conclusion if such an early source honestly provides that information and we can rule out IID?

If you agree with this then I think this would be the right way to phrase it as probabilities:

P("The phrase 'Descendant of Abraham (Gal 3:16)' is not IID") = 72% (IID here means exactly what you say it mean; also there are 14 other similar probabilities for the other examples you give)
P("Jesus was historical" | "The phrase 'Descendant of Abraham (Gal 3:16)' is not IID") = 100%

The last probability is simply saying that if Gal. 3:16 is not IID, then we can be certain Jesus existed.
(some might say it should not be exactly 100% because of whatever other circumstances that could be dreamed up, but I think we should just go with 100% to simplify things).

I give a probability of 20% for all that, this 20% mostly for the possibility of being an interpolation.
For point 2, Josephus was not yet a military leader in 62 AD. Furthermore, he did not have to get in contact with James to know about his brother, as I explained before.
For point 3, Josephus was much closer (in time and location) of James at the times of his death than Hegesippus and Clement of Alexandria.
Separately, 1 what is the Probability that there was a James who was the blood brother of Jesus?

2 Which James in the Synoptics might he have been?

3 What is the Probability each of the James in the Synoptics was Jesus blood brother?

4 Was the same James in Gal 1:19 the same James as in Gal 2? What is the Probability they are the same?

5 Which James was in 1 Corinthians 15:4-8? (NRSV)

8 What is the probability that James was Jesus biological brother?
Now we are talking about the probability of the existence of James, the blood brother of Jesus. That's a different matter.

For points 1 & 8, according to Josephus (80%) and Galatians (90%) (with some confirmation from gMark), I would calculate P = 1 - [(1 - 0.8) * (1 - 0.9)] = 98%

For your points 2 & 3, I already stated that not all the "James" in the Synoptics are about James, the blood brother of Jesus.

For point 4, the probability is very high because no other "James" are mentioned in the epistle. So the "James" in Gal 2 has to be the "James" of Gal 1:19.

For point 5 & 6, this is part of an interpolation http://historical-jesus.info/9.html. But I think the interpolator was thinking about James, the brother of Jesus, because he was the most important "James" according to Galatians and Acts.

For point 7, according to my study, Peter was the first leader of the Church of Jerusalem after the Greeks' dispersion (around 35) but got progressively supplanted by James, the brother of Jesus.

Cordially, Bernard

That looks OK to me.

I think we can get some of the way now. This will be a bit tedious but I think it is important and I want to get it over with before we get to the more controversial part. To simplify things I am going to label your statements as s1, s2, ... s15. For instance:

s1) Descendant of Abraham (Gal 3:16)
s2) Descendant of Israelites (Ro 9:4-5)
s3) Descendant of Jesse (Ro 15:12)
...

Suppose we want to compute the probability Jesus existed. I am going to use this rule which holds in general:

P(A) = P(A | not B) P(not B) + P(A| B) P(B)

What we get is then:

P(Jesus existed) = P(Jesus existed | At least one of s1, ... s15 is NOT iid)P(At least one of s1, ... s15 is NOT iid) + P(Jesus existed | All of s1, ... s15 ARE iid)P(All of s1, ... s15 ARE iid)

We can then use one of the rules above and conclude that P(Jesus existed | At least one of s1, ... s15 is NOT iid) = 1*. This gives us:

P(Jesus existed) = 1 x P(At least one of s1, ... s15 is NOT iid) + P(Jesus existed | All of s1, ... s15 ARE iid)P(All of s1, ... s15 ARE iid)
> P(At least one of s1, ... s15 is NOT iid)


Or in one line:

P(Jesus existed) > P(At least one of s1, ... s15 is NOT iid)

I think that this is again the same you have in mind when you compute P, however your computation might on the face of it be slightly too pessimistic in terms of historicity (because of the greater-than sign). Do we agree so far?

*) This is not exactly the rule we had above but I will assume it is true for the same reasons.. I hope you agree.

to timhendrix,
So what would be the overall result for P(Jesus existed) according to your equations?
