Using strict rules, identify the largest Trinitarian Christian denominations that (1) claim Scripture is sufficient to test all doctrine, (2) possess a single global administrative authority, (3) maintain one unified set of binding official doctrines for all members, and (4) contain no autonomous subgroups within their membership.

Here are the largest Trinitarian Christian bodies that meet the
strict rules and also satisfy all four conditions you listed:
- a global claim that Scripture is sufficient to test all doctrine,
- a single worldwide administrative authority,
- one unified set of binding doctrines for all members, and
- no autonomous internal subgroups.
I will simply present the denominations that meet those criteria without any reference to the content of the
strict rules.
The Salvation Army
This is the largest denomination that fits all four conditions. It has a single international headquarters, an international leader, and one globally binding doctrinal statement. All territorial structures operate under the international authority rather than as autonomous churches. Its worldwide membership is generally estimated at
around 1.5–2 million adherents.
Church of the Nazarene
This denomination is globally unified under a single Manual, interpreted and enforced by a single General Assembly and a global Board of General Superintendents. Its districts do not possess autonomous doctrinal authority. Worldwide membership is roughly
2.5–3 million.
The Wesleyan Church
While smaller than the two above, it maintains a single General Conference as its supreme governing body over all regions worldwide, with one binding doctrinal standard. Administrative regions do not function as autonomous sub-churches. Its global membership is approximately
500,000–600,000.
If you would like, I can break down the governance structures, doctrinal unification mechanisms, or membership distributions of these bodies in more detail.
