It's precisely because I enjoyed the book that I'm typing up this review. It's mostly a collection of my criticisms. There's no point in commenting on the positives of the book other than to say that Maier can write an enjoyable story. I personally like Paul Maier, but I'm dissappointed in some aspects of the book. He makes some mistakes which are regrettable. Some of them due to the fact that he sometimes discusses topics outside of his expertise. My comments will be succinct since they're really made for those who have already read the book. So, they'll know the context in which I'm making them. My comments won't be in any particular chronological or logical order.
WARNING!!!
Spoilers Ahead!!!!! DO NOT continue reading if you don't want the story of the book revealed. Read the book first, then read this review afterwards (if you wish).
The arguments the Muslim characters in the book make are the standard bad arguments that popular Muslim apologists often use for Islam and against Christianity. One would have expected the character Abbas al-Rashid to have used better arguments (like those used by the real life apologist Shabir Ally).
In the debate between Jon Weber and Abbas al-Rashid, Jon (the Christian) does a pretty bad job at defending the doctrine of the Trinity. For example, in addressing Islamic incredulity regarding the Trinity, Weber cites Augustine twice (pp. 157 & 173) as saying "Credo ut absurdum est!" and translating it "I believe because it is absurd". Upon reading that, it seemed to me that maybe Maier accidentally attributed to Augustine what Tertullian actually wrote ("prorsus credibile est, quia ineptum est"). How is that supposed to engender belief in the doctrine if you start out admitting it's absurd or illogical? Maier as a (fellow) Christian should have been more careful.
On page 156 Weber says, "Similarly three golden denarii are three in number but one in essence: gold. The one does not contradict the other...." The character Weber is supposed to be a Lutheran (like the author himself). In which case, Lutherans (and Evangelicals in general) believe God is one in being/essence and three in person. While some scholars have argued that some of the early ecumenical councils taught the distinct beings of the Father, Son and Holy Spirit who share generic unity, not numeric unity; this view is virtually rejected by all Evangelicals. I myself am open to this view that some have called "Nicene Monarchism" [generic unity], though my provisional and default position is the standard Evangelical understanding [numeric unity]. I suppose one could argue that the character saw himself as going back to the original intent of Nicaea I. But that's nowhere in the text of the novel itself.
On page 152 the narrator says, "Jon was less than comfortable in realizing that Abbas had immediately attacked the one logical weak point of Christianity." The fact is that there are various formulations of the Trinity that aren't formally and explicitly contradictory. That Maier would leave it at that in the book is a disservice to Christianity. It gives all readers of his novel (whether Christian, Muslim, atheist, et cetera) the impression that the doctrine of the Trinity actually is illogical, or that Christian apologists don't have solid answers to such criticisms. Which they do. One of my own blogs is devoted solely to defend the doctrine of the Trinity.
On page 249 Second Acts has Paul referring to Jesus as "the emanation of God." While some of the early church fathers conceived of the Logos as a kind of emanation, nowhere does the apostle Paul teach that in the canonical Scriptures. That can give modern readers the impression that that's a standard understanding of the Logos among modern Trinitarians Since it's Maier who's inventing the dialogue in 2nd Acts. Maybe Maier is expressing his own unique personal view of the Logos and of Christology in the narrative. But, it certainly would confuse or misinform some people who might be trying to learn theology from the novel. Something people will naturally do, even though they should know better than to do that with fiction.
On page 113 Weber finds the books by the "Caner brothers" helpful in preparation for his debate. Maier should know that the Caner brothers are proven frauds (cf. the various exposés by Christian apologists like James White). Weber also prepared for the debate in isolation when he would have been smart to enlist help from some Christian apologists whose expertise is on Islam (e.g. Nabeel Qureshi [when he was still alive], David Wood, James White et al).
Weber could have declined the invitation to debate since he's not an expert in Islam. That could have freed him up to do the other things he was more eager to do.
The narrator (presumably representing Maier's views) isn't neutral on the issue of whether Islam is a religion of peace or not, or whether terrorism is a genuine or inauthentic expression of Islam. Not only Christians, but Muslims are in disagreement among themselves on this issue. Yet the narrator takes a side. Even saying Jihadist terrorism is a "hijack[ing of] Islam" (p. 387) and approvingly cites Tahir ul-Qadri's public declaration that [in the words of Maier's book] "terrorists were the very enemies of Islam and that suicide bombers were destined not for heaven but for hell" [p. 387]. The fact is that a good case could be made that Islam is not a religion of peace, but of terror. See the materials by David Wood, Robert Spencer [not to be confused with white supremacist Richard B. Spencer], Sam Shamoun et al.
On page 186 Weber's Roman Catholic friend and priest Monsignor Kevin Sullivan says that the Pope was so pleased with Jon that the Pope could almost have given him a red hat [i.e. the position of Cardinal in the Catholic Church]. Weber then says that in order for that to happen, he would need to convert and dissolve his marriage, since priests aren't allowed to be married. Apparently Maier doesn't know that special dispensations have been given by the Roman Catholic Church for converts who were high ranking church ministers in their former denomination to become priests in the Catholic Church while also keeping their wives.
On page 158 Weber refers to the similarity between the Dead Sea Scroll of Isaiah and the Masoretic text. Yet, that gives a false impression that could trip up some Christians if they knew that that kind of similarity is missing in the Masoretic text and the Dead Sea Scrolls regarding the book of the Jeremiah and other manuscripts/fragments (et cetera). He makes similar statements regarding the New Testament text on page 157 even though there are entire pericopes which are disputed (e.g. the longer ending of Mark, the Pericope Adulterae, the Comma Johanneum etc.). The issues are more complex than Weber acknowledges, even though the textual difficulties don't jeopardize the truth of Christianity. At least Weber/Maier acknowledges and mentions the questionable nature of Mark 16:9-20 in the rest of the novel. In fact, it's a central issue since the discovered Constantine Codex allegedly contains the real ending of GMark.
On page 172 Weber states that the Caliph Uthman first wrote down the Qur'an 20 years after Muhammad's death. No, there were already many competing collections of the Qur'an circulating at the time. Uthman wasn't the first to write down portions of the Qur'an. Rather, Uthman was the one who standardized the text by publishing his own version after telling everyone to give him their copies and burning their different versions. By doing so he destroyed vital evidence for reconstructing other versions of the Qur'an that were then extant. Whereas on the Christian side, the very multiplicity of textual variants AID in reconstructing the original autographa to a high degree of accuracy.
On page 177 Weber thinks the Islamic doctrine of abrogation undermines Allah's perfection. But that doesn't necessary follow. In fact, a similarly bad argument could be made against Christianity in that God "replaced" the Old Testament with the New Testament. I would argue that it really wasn't replaced since the Old predicted and anticipated the New. The New builds on the Old without completely replacing it. Having said that, it's true that the ceremonial laws in the Mosaic Covenant are no longer binding on Christians. In which case, Weber's mental—but unspoken—criticism would apply to Christianity. Weber silently thinks, "Well, why didn't the deity get it right the first time? Didn't he have a second cup of coffee that day?" Instead, Weber states in the debate a more modest criticism, "One only wonders why anything that God did or said would need improvement." If misapplied, this type of criticism would require a misrepresentation of both Islam and Christianity to work. If properly applied, it would only damage (true) Islam. And that to a lesser degree than most objectors to Islam would like.
Though, Weber does give some good arguments against Islam in the course of the debate. For example, on page 180 he points out that that the truth of Islam hinges on the testimony of one man (Muhammad), whereas the truth of Christianity hinges on the testimony of many (including Jesus, the Apostles, and the other disciples etc.). Maier rightly points out in the novel that Muhammad originally wondered whether he was seized by an evil spirit or jinn. And so, making Muhammad's claims that less reliable or trustworthy. Since it basically boils down to the testimony of one man. A single man who feared he might have been demonized or possessed by an evil spirit. Unfortunately, if I recall correctly, Maier/Weber didn't used that argument even though he acknowledges the historical fact of Muhammad's original fear and suspicion.
Weber was unwilling to use the Hadith to criticize Islam because even Christians have unreliable traditions and legends. However, some of the stories in the Hadith are considered more reliable than others. He could have used those which have historically been considered more reliable than the others to undermine Islam. Depending on the Islamic sect, some accept the Hadith (plural: ahadith) to have some value, while others hold to only to the Qur'an. Nevertheless, some of those traditions are so embarrassing and damaging to Islam that some Islamic apologists who belong to sects that accept the Hadith have basically abandoned their former stance on their reliability. Or at least disagree with the grading and levels of reliability traditionally attributed to each tradition or story.
The debate between Weber and al-Rashid was an all day affair, yet there's no mention of periodic breaks to accommodate the Islamic practice of prayers fives times a day.
Muhammad is said to have given a general amnesty when he returned and conquered Mecca. Yes, it was a "general" amnesty, but some of Muhammad's enemies were still specifically sought out and executed.
On the one hand Weber acknowledges that there are parallel (apparent) problems between Christianity and Islam. For example, 1. OT law and Islamic Sharia, 2. the behavior of Christians during the Crusades and Spanish Inquisition, Jews during the invasion of Canaan and Muslim Jihad. Weber points out that these parallels make it that Christians have to be careful how they criticize Islam because such criticism could backfire on their own Christian position. Yet, on the other hand, Weber does make such criticisms of Islam with no further explanation. For example, Weber claims the sharia laws of the Qur'an are demeaning to women. Yet, non-Christians could (though wrongly) claim the same thing about the Bible. Weber's criticism seem contradictory or inconsistent because they're incomplete.
Shouldn't Weber have realized that if he were discovered disturbing the possible tomb of the apostle Paul that he could be jeopardizing the credibility of his work on the Constantine Codex? The very opposite of what he's trying to do by investigating the tomb. He could have destroyed his career and financially affected his wife. Speaking of his wife, why would he allow her to attend a debate where he knows he could be assassinated (having a fatwa issued for his death). If a bomb was used, she could have died too!
If Weber knew there was a small possibility that his friend Osman al-Ghazali may have been involved in the theft of the Codex, why interrogate him alone and in the same room as where the Codex is in? Couldn't he have thought in advanced that IF Osman was guilty that it would be dangerous to have the book around in his presence and in the open (unlocked and unsecured)? That's just stupid on Weber's part. In fact, while reading the story I suspected that the codex on the desk was actually the fake one and that the whole interrogation was a setup by Weber and the CIA. With the CIA listening in on the conversation in another room waiting to barge in once enough evidence was recorded to arrest Osman.
The novel seems to conflate the authenticity of the Codex with the authenticity of the texts of the ending of Mark and Second Acts. That doesn't follow at all. EVEN IF the entire Codex is one of the 50 books Constantine issued to be made of the New Testament, that doesn't thereby prove that the additions to Mark and Second Acts is truly apostolic [what I'll sometimes call +Mk&2A for short]. Constantine lived in the 4th century. Both the additions of Mark and 2nd Acts could have been forgeries that were made between the time of the Apostles and the 4th century. Constantine and Eusebius could have made an honest mistake about the authenticity of those texts. Moreover, if +Mk&2A were really in Constantine's copies, they would have likely left more of a mark among the Church fathers. The patristic literature would have cited and quoted them both before & after Constantine's time. Real scholars would not have conflated the two distinct issues.
On page 351 one of the correct criteria listed for possible canonicity is "and that were widely used in worship". Unfortunately, +Mk&2A fails that criteria since there is no textual or historical evidence for them in the patristic literature or manuscripts evidence of the New Testament. That's why the whole idea that an Ecumenical Council could vote on their canonicity is ridiculous. In the narrative of the novel the vote wouldn't be considered universally binding, despite the fact that historically Ecumenical Councils have been considered infallible by Catholics (e.g. Roman Catholics, Eastern Orthodox).
Also, the idea that they would vote using electronic devices is laughable [p. 378]. I literally laughed out loud when I read that. Why would very traditional denominations like Catholicism and Orthodoxy demean themselves by using electronic devices in this way? Think of how Popes are still being elected. The Protestants who were invited to the council would also be the first to raise concerns of possible hacking and fraud when it comes to the results. Additionally, the displaying of the results while the votes were being made would psychologically influence the voters. To prevent the Bandwagon Effect, a real council would have only tallied the votes AFTER everyone had voted.
Contrary to Catholic claims, the canon of the Old and New Testaments weren't determined by any Ecumenical Council, or even a local synod. There was no Jewish council that determined the OT canon (Jamnia was too late), and the NT canon was apparently settled long before the council of Hippo (393), council of Carthage (397) or the council of Trent (c. 1545-1563). Athanasius listed the exact same NT canon we have in his 39th festal letter years before the council of Hippo. So, why would +Mk&2A require an Ecumenical Council for inclusion into the canon when no other canonical book was determined in that fashion in the past?
On page 375 we're supposed to believe that the Eastern Orthodox would accept the Western [i.e. Roman Catholic] Calendar and aspects of their liturgical season. That's HIGHLY unlikely!!! This is so improbable that it's more likely that they would first submit to the Pope as Supreme Pontiff of the Universal Church, before they would accept Rome's calendar. In which case they would cease being Eastern Orthodox and be Roman Catholics (or Western Rite Orthodox). Then the issue of the Calendar would become moot. Because, being in submission to the Bishop of Rome, they could naturally accept the Catholic Calendar.
In my view, the book is overly ecumenical. Naively so. See for example pages 292-293 as well as (and especially) the very ending of the book that describes the hypothetical Ecumenical Council. Maier unfortunately sweeps under the rug the real and important differences between the various Christian denominations. Though, at page 392 in his "Reality Note" he admits that a real Ecumenical Council would be VERY difficult to pull off at the present time in the history of the Church.
I could include other criticism and factual errors but this review has gotten too long. The criticisms I have mentioned should be enough to remind people to read everything critically. To not assume everything as "gospel truth" from even your favorite authors. Check it out for yourself. Investigate the issues.
