Recent, under-informed assertions about the Book of Mormon and archaeology prompt this discussion.
Let's ask a simple question:
What archaeological evidence do we have that the Council of Nicaea ever took place?Unlike Zarahemla, or the Mitanni capital of Washshukanni, Nicaea is a site whose location is known. It has been excavated. We know what is there.
Archaeologically, Nicaea (modern Iznik) is most famous for its ceramic tiles, but they date from the Ottoman period. On the other end of the time spectrum, some neolithic pottery has been found at Iznik (Machteld J. Mellink, "Archaeology in Anatolia," American Journal of Archaeology 89/4 (1985): 549).
The theater is 1st century, a typical Hadrianic style building that would have seated about 15,000 people. (Marie-Henriette Gates, "Archaeology in Turkey," American Journal of Archaeology 98/2 (1994): 276.)
The city wall is also first century with numerous renovations in later times.
The church at Nicaea is 6th century (William Tabbernee, "Asia Minor and Cyprus," in Early Christianity in Contexts, ed. William Tabbernee [Grand Rapids, Michigan: Baker Academic, 2014], 307.) The Koimeisis Church dates to the early eighth century (SEG XLI 1099) or late seventh century (SEG XLIV 1007).
So all of the Christian structures date at least two centuries after the Council of Nicaea. This is problematic.
The epigraphic corpus for Nicaea is extensive: Sencer Sahin, Katalog der antiken Inschriften des Museums von Iznik (Nikaia), 4 vols. (Bonn: Rudolf Habelt Verlag, 1979-87). With four volumes of inscriptions plus numerous additions in the SEG (Supplementum Epigraphicum Graecum), it is clear that Nicaea has more inscriptions than most Mesoamerican sites.
As far as epigraphic evidence we have:
1st century BC
- a first century BC epitaph (SEG XXIX 1289).

- an inscription of Nero (AD 54-68) regarding street repair (I Iznik I 13 = CIG 3743)

- a fragmentary third century epitaph (SEG XXIX 1292).
- a milestone of Diocletian and Maximian (AD 286-293) (I Iznik I 22)

- a fourth century Jewish inscription quoting Psalm 135:25 (I Iznik II 615 = SEG XLVIII 1499)
- an undated dedication to Ti. Claudius Aelianos Sabinos (I Iznik I 35 = SEG XXIX 1284).

- four undated Christian inscriptions (SEG XXIX 1339-42)
- four undated Christian epitaphs (SEG XXIX 1319, 1325, 1331-32)
- an undated testamentary regulation (SEG XLIX 1790)
There appears to be no archaeological evidence that Constantine was ever in Nicaea, nor that there was a Christian council held there in the fourth century, and, of course, no archaeological evidence for the content of the Nicaean Creed. Should millions of creedal Christians therefore abandon their faith? They cannot point to a single piece of archaeological or epigraphic evidence that the Council of Nicaea ever took place. No reputable archaeologist has ever produced any. I can find no record of any reputable archaeological journals that have published any archaeological evidence that the Council ever took place or that support the creed that it supposedly produced.
Anyone who has actually worked trying to integrate archaeological with historical data can spot the problems with this sort of analysis easily. Some people, however, want to apply a double standard applying different standards to the Book of Mormon than they do to other historical events.
