In a recent work critical of “Mormonism,” John Wayne Wardell (Protestant) offered the following criticism of Latter-day Saint claims to modern public revelation and a defense of Sola Scriptura through an appeal to Hebrews 1:1-2
Mormon believers feel quite the
opposite, that the Book of Mormon is God’s new revelation. Yet traditional
Christianity teaches that all written revelation ended in the era of the New
Testament. Hebrews 1:1-2 is often sued in this regard as a support text: “(1)
God, who at sundry times and in divers manners spake in time past unto the
fathers by the prophets, (2) Hath in these last days spoken unto us by his Son,
whom he hath appointed their of all things, by whom also he made the world.”
This is interpreted by most theologians of the established churches to mean
that with the coming of God’s son 2000 years ago, “the end of days” has begun
and the end of new revelation with it. The Gospels and the other books of the
New Testament are the preserved record of that revelation which is the inspired
account of the life teaching of Jesus Christ, God’s final prophetic voice to
the world. Thus, any additional written revelation by any professed Prophet
thereafter is a multitude of years too late. (John Wayne Wardell, The
Footprints of Mormonism [London: Austin Macauley Publishers, 2025], 244)
There are many things wrong about an appeal to Heb 1:1-2 to
support the cessation of public revelation.
appealing to such an absolutised reading of Heb 1:1-2 results in one rejecting the personal pre-existence of Jesus; to quote Dave Burke, a Christadelphian apologist:
I find it interesting that you cite Hebrews 1:1-13 as your text and then completely ignore verse 1. Perhaps it’s because you’re not sure how to deal with this verse, which clearly states that God formerly spoke to people through His prophets, but has spoken through His Son ‘in these last days.’ Such a statement has obvious implications for the concept of Jesus’ pre-existence and undermines the popular claim that OT angelic theophanies were actually appearances of the pre-incarnate Christ.
In response to this, the Evangelical apologist in the debate answered Burke rather cogently. In spite of my disagreement with this critic about the essentials of the gospel, I think he is spot-on in (1) answering the common Socinian abuse of this pericope (Anthony Buzzard often appeals to this text, for instance) and (2) that it does not preclude post-ascension prophets and apostles (this point will be fleshed out more later in this section):
You seem to reach for arguments from silence a lot, Dave. I said nothing specifically about verse 1 because I had a lot of ground to cover and little room to cover it. Verse 1 poses absolutely no problem for my Christology. God spoke in the past in the prophets; in these last days he has spoken to us in the Son. This statement has no implications, obvious or otherwise, as to when the Son began to exist. Nor does this statement mean that the Son could not have spoken as the preincarnate angel of the LORD. By your reasoning, the order is rigidly (1) prophets and no Son, (2) Son and no prophets. But we know, as it turns out, that there were prophets after the Son came (Acts 11:27; 13:1; 15:32; 21:10; 1 Cor. 12:28-29; 14:29, 32, 37; Eph. 2:20; 3:5; 4:11). The author’s point is simply that the revelation that came through the Son “in these last days” represents the climax, the high point, of the history of revelation. (source)
Furthermore, note that the New Testament affirms true prophets after the death, resurrection, and ascension of Jesus:
Even in the teachings of Jesus, there is an expectation of true prophets that would come after Him:
Additionally, Christ not only would send/commission prophets, but His followers were to accept them as true prophets of God:
Furthermore, in Rev 11:3-12, there is a promise of two eschatological prophets who would serve as two (true) witnesses of God against a fallen world and who would be killed.
To quote a scholarly Protestant source:
In the NT, most of the references
to prophets are to ot figures or to their writings. These references are used
primarily to authenticate the messianic identity of Jesus and his ministry
(Matt 1:22; 2:23). In this sense, prophets are presented not only as people who
proclaimed the divine word, but also as those who foretold the coming of the
Messiah. John the Baptist is referred to as a prophet (Matt 11:9; 14:5; 21:26;
Luke 1:76), and this is the common opinion of the people concerning Jesus as
well (Matt 21:11, 46; Luke 7:16; 24:19; John 4:19; 6:14; 9:17). The early
church clearly identified Jesus with the prophet like Moses (nābîʾ) foretold in Deut 18:15 (Acts
3:22; 7:37). Other prophets (prophētēs)
mentioned by name are Agabus (Acts 11:27–28; 21:10); Judas and Silas (Acts
15:32); and Barnabas, Simeon, Lucius of Cyrene, Manaen, and Saul/Paul (Acts
13:1), as well as the prophetess (προφῆτις,
prophētis) Anna (Luke 2:36). The
woman identified in Revelation as Jezebel also claims the title of prophet (prophētis) but is in fact a false
prophet (Rev 2:20). Paul refers to the Cretan poet Epimenides as a prophet (prophētēs) in Titus 1:12. In the Pauline
epistles, prophets (prophētēs) are
listed alongside apostles, pastors, and teachers as those whom God has equipped
to lead the church (Rom 12:6; 1 Cor 12:28–29; Eph 4:11). A major role of these
individuals is to edify and encourage believers (1 Cor 14:3; see Acts 15:32).
The New Testament, like the OT, condemns false prophets (ψευδοπροφήτης, pseudoprophētēs) for being illegitimate and for teaching false
doctrine (Matt 7:15; 24:11, 24; Mark 13:22; 2 Pet 2:1). (Aaron C. Fenlason, “Prophets,”
in Lexham Theological Wordbook, ed. Douglas Mangum et al. [Lexham Bible
Reference Series; Bellingham, Wash.: Lexham Press, 2014], Logos Bible Software edition)
If Wardell is correct, it means that none of the books written after the ascension (i.e., all 27 books of the New Testament) are not inspired works, but merely useful historical records en par with the importance of 1 Clement and the Didache. Furthermore, it would mean that, prior to the incarnation, Jesus was passive during Old Testament times, contrary to the early Christian belief that the Angel of the Lord and Jesus were numerically one and the same person.
