The Mormon Doctrine of Deity: The Roberts-Van Der Donckt Discussion To which is added a discourse, Jesus Christ, the revelation of God; also a collection of authoritative — Reading Companion

Argumentative Voice and Scriptural Strategy

Roberts's prose is marked by a combative clarity. He frequently addresses his opponent directly, as in the passage where he writes, "Mr. V.'s argument is that if Jesus had only declared his moral not his physical union with God, the Jews would not have taken up stones." This direct engagement gives the text the feel of a live debate. Roberts relies heavily on scriptural cross-referencing, often juxtaposing passages to challenge Van der Donckt's interpretations. For instance, he counters an argument about John 10:30 by introducing John 5:15-18, where the Jews seek to kill Jesus for claiming equality with God, not identity. This method reveals a careful reader who expects his audience to follow detailed exegetical reasoning.

Shifts Between Polemic and Doctrinal Exposition

The work alternates between sharp rebuttal and broader doctrinal explanation. In the preface, Roberts adopts a sweeping historical perspective, asserting that "in nothing have men so far departed from revealed truth as in their conceptions of God." This macro-level claim contrasts with the micro-level textual analysis in later sections, where he parses Latin phrases like unum sumus to argue that the same term applied to the disciples' unity cannot denote physical essence. The shift in pace is notable: the preface moves in broad, declarative strokes, while the debate sections slow to a meticulous, almost legalistic examination of words and their contexts. This variation keeps the reader engaged across the work's considerable length.

Recurring Structural Patterns in the Debate

Roberts employs a consistent structural pattern: he states Van der Donckt's position, then presents a counter-argument using an alternative scriptural passage or a logical extension of the opponent's own reasoning. For example, he tests Van der Donckt's exegesis of John 10:30 by applying the same logic to Jesus's prayer in John 17, where the disciples are to be "one" as the Father and Son are one. This pattern of testing and extending creates a rhythm of assertion and refutation. The footnotes, which cite early church fathers like Tertullian and Origen, add another layer, grounding the debate in patristic authority. These structural choices reveal a methodical mind that values consistency and precedent.

Language of Physicality and Personhood

A striking feature of Roberts's language is his insistence on the physical, personal nature of God. He repeatedly uses phrases like "two distinct personages" and "like men in form," emphasizing that the Father and Son are separate individuals. This vocabulary stands in deliberate contrast to abstract theological terms. When discussing the phrase "I and my Father are one," Roberts resists a metaphysical reading, instead arguing for a unity of purpose. His choice of words—"personages," "individuals," "form," "features"—anchors the discussion in concrete, anthropomorphic terms. This lexical preference shapes the entire argument, making the debate as much about the proper language for describing God as about doctrine itself.

Readers approaching this text will benefit from attending to Roberts's rhetorical moves as much as his theological claims. The work rewards those who follow its scriptural references closely, as the argument often hinges on the precise wording of verses. The footnotes, while scholarly, are integral to the debate's texture. This is not a neutral exposition but a partisan engagement, and its value lies in the clarity with which it articulates a specific Mormon perspective on the nature of God.

Both argue for a singular God, yet in Roberts’s fierce defenses and van der Donckt’s challenges, I hear the same lonely ardour that hums through the other volume. Each author feared their sacred was misunderstood. That quiet kinship—of two believers, worlds apart, each convinced they spoke the truth—has stayed with me. I think of The Islam of Mohamed — Background and Themes and its patient certainty.
