Chapter 11 of 12 · The case for Orthodoxy
Sources, Method, and How to Verify Everything
The complete bibliography of the case, the citation standard used throughout, and an explanation of why each class of source can be trusted and how any claim on this site can be checked by an ordinary reader in under a minute.
This page is the contract between this site and its reader. It states the standard of evidence the site holds itself to, explains how every citation can be verified, names the sources in full, and declares the site's position so that the reader can discount for bias. A website that cites its sources but hides its method is a nicer propaganda; this page is the anti-propaganda.
1. The citation standard
- Every factual or doctrinal claim carries a marker. Click any footnote number: you will get the exact source — author, work, section, translation or edition, and (where the document is online) a working link to the primary text itself.
- Primary sources are preferred everywhere they exist. This site cites councils, canons, papal bulls, encyclicals, synodal acts, the Fathers, and the Bible — not other apologists. Where a factual event is documented only in secondary scholarship (e.g., the date of a medieval synod), the secondary source is named, and it is chosen from standard scholarly or official reference works, including Catholic sources, so that the reader is never asked to take the author's word against the author's own tradition.
- Adversarial sources are quoted, not paraphrased away — and the whole site is set in the form of the scholastic disputed question (the form of St. Thomas Aquinas). Every chapter is an article: Whether…; the strongest objections, cited to their own sources; the sed contra, quoting authorities the opposing side itself recognizes; the respondeo (“I answer that”); and the replies to each objection in order. The form is chosen because it enforces the site’s standard: an objection that is merely waved off is a lost chapter, and the reader can verify every objection and every reply against the same kind of citation. The Filioque chapter quotes Pope Leo III’s behavior through the Eastern Encyclical but also through the Catholic Encyclopedia; the Rome chapter quotes Irenaeus and Leo’s Tome in their force; Chapter 10 states the best case for Rome in its strongest form. A claim survives only if it survives that.
- Disputed points are marked as disputed. Where Catholic and Orthodox historians disagree (e.g., the canonical status of the Council of Constantinople 879–880; Pope John VIII's ratification), the site says so rather than resolving by authority.
- Every external link was checked. At the time of publication, every URL in this site's footnotes was fetched and verified to return a live document (HTTP 200) using an automated link check. Documents move; if a link is ever broken, the full reference is printed beside it so the reader can locate the text independently by title, section, and standard collection (e.g., "Denzinger 856"; "NPNF2-14, Council of Chalcedon, Canon 28"). Access dates are recorded in the site's repository.
How to verify any claim in under a minute
Choose any footnote on any page. Open its link in a browser. Find the passage named (the footnote gives the section). Compare it with the sentence in the article. That is the entire procedure. No gatekeeping, no subscription required: the vast majority of sources are public-domain patristic and conciliar texts in standard scholarly editions, or official Vatican/Official Church documents on the churches' own domains. Where a text exists only in print (for example the modern critical editions of the Philokalia), the footnote says so and gives the exact edition and page. Nothing on this site requires you to trust it.
2. Position and disclosure
This site is written by one author, an inquirer who came to the Orthodox position after weighing the evidence documented here, and who has tried — genuinely and at length — to sustain the Catholic case, and could not. Disclosures required by honesty: (a) the author is not a clergyman or a professional theologian; the site is a layman's disciplined summary of primary sources, and where it errs, the footnotes will reveal it; (b) the author is not an enemy of the Roman Catholic Church, which is acknowledged throughout as a Christian communion of great learning, holiness, and suffering, and as the legitimate heir of much of the first-millennium West; (c) every citation to Catholic sources is to the sources' own words, so that a Catholic reader can conduct the whole debate from Catholic materials alone. The purpose of the site is not victory in a debate but the location, as precisely as documents allow, of the Church of the Seven Councils, in which a soul may safely stand.
3. Where to go next (for those who wish to proceed)
A decision of the conscience cannot be made by bibliography alone, but the following, all of them ordinary and public, are the next honest steps a searching soul can take: (1) attend the Divine Liturgy of a canonical Orthodox parish, and speak to the priest afterwards — the Church receives inquirers without requiring acceptance of anything beyond what is documented here; (2) read the Philokalia's introduction and the life of a modern saint (e.g., St. Silouan the Athonite) to see the faith lived, not merely argued; (3) ask an Orthodox priest about baptismal initiation — the Mysteries are the Church's own method of healing; (4) repeat the method of this site yourself on one contested point, e.g., the Creed: verify the dates in Chapter 1 from Catholic and neutral sources, and see where the documents, not the traditions, lead. The author's prayer is that the reader's conclusion be reached more honestly than the author's own first answer was.

5. Verification record
The site was built by an automated pipeline (build.py + site.json), and every external URL in its footnotes was verified live (HTTP 200) at build time, then again before publication. The verification script and its output are part of the repository (tools/check-links.sh) and can be rerun by anyone at any time. Print references use standard, numbered editions that any library can supply. Where a cited online source is a mirror of a standard text (e.g., newadvent's NPNF scans), the underlying print edition is named in the same footnote.
Notes
- Fair use statement: quotations are brief, are drawn from public-domain translations (NPNF/ANF series, KJV Scripture) or from officially published Church documents, and are used for scholarly comment; the site itself is released under a permissive license in its repository (see the README).
