# Cunctos populos of 28 February 380 defines Nicene Trinitarian Christianity as the licit public faith of imperial subjects

Date: 380

## The fact

Fordham’s Book XVI extract prints Cunctos populos as an edict that all peoples under the emperors should follow the religion of Damasus and Peter of Alexandria. Britannica independently records the 28 February 380 creed-edict.

It is one event.

## Context

A civil edict that names non-Nicene Christians as foolish madmen is a minority-rights harm heading. Pagan temple laws of 391–392 are later and different. Baptism later in 380 is neighbouring biography, not this text.

[Theodosius I](/people/theodosius-i)’s documented role is bounded by other offices and collaborators named in the sources below. Sharing a field with them is not a reason to drop a documented act, and it is not a reason to assign later consequences done in the name after death.

CTh 16.1.2, issued from Thessalonica to the people of [Constantinople](/people/bartholomew-i-of-constantinople), names Damasus and Peter of Alexandria as the measure of Catholic faith. Britannica: prescribed without consulting ecclesiastical authorities; first documentary use of Catholic Christians in this sense. Not a 391 temple law. Not an overnight ban of all paganism.

Named person as heading of the dated public instrument. Later editors, museums, printers, or offices share publication. Complex where later carriers are the surviving public file.

## Evidence and sources

Fordham — Codex Theodosianus, selections from Book XVI and Britannica — Theodosius I independently describe this instrument.

Official or archival record: Fordham — Codex Theodosianus, selections from Book XVI (https://sourcebooks.fordham.edu/source/theodcodeXVI.asp; Fordham University / Internet History Sourcebooks).

## Significance

Cunctos populos is a rights-harm path of high confidence on the constitution’s wording as later compiled.

## What is established and what is not

Established as a sourced public record of this instrument at the date assigned here.

What would change the picture: a contradictory original with a different date or name, or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of later institutions.

The date is the date of this instrument, not a licence to back-date every later harm or benefit.

Established here: a sourced, dated public instrument with a named contribution by Theodosius I.

They are not a public rating.

The driver `protection-of-minority-rights` is attached because the mechanism named in Significance follows from this instrument, not because a standing list of welfare headings needed another tick. Theodosius I did not file a later UNESCO form, a later Loeb colophon, or a later museum label as a personal act. A portrait or conventional bust is not this mechanism. Allegation, reconstruction, and established occurrence stay distinct. Do not call this the closure of every temple. Do not date it 438. Keep the carrier date of later English distinct from the received historical year stored in the date field. Do not read a later English edition as a recovered autograph of Theodosius I.
