“Prove all things; hold fast that which is good. Abstain from all appearance of evil.” 1 Thessalonians 5:21–22
Sixteen traditions measured against one Book. Fourteen Protestant families, Roman Catholicism, and Eastern Orthodoxy, scored two ways from the King James Bible: adherence to nine doctrinal teachings of Jesus and the Apostle Paul, and violation of nine teachings Christ and Paul explicitly warned against. What a church keeps builds its score; what it practices against the Book drains it.
Every tradition below is weighed twice against the same Book.
Nine doctrinal teachings from the words of Jesus and the Apostle Paul: Scripture’s authority, grace through faith, baptism, the Supper, church order, worship, prayer as Jesus taught, discipleship, and the unaltered gospel. Keeping them builds the score.
Nine practices Christ and Paul named and warned against: idols, other mediators, seeking the dead, vain repetitions, exalted titles, forbidden marriage, works-salvation, extra revelation, and mammon. Holding them as doctrine drains it.
Doctrinal teachings and plain truth from Jesus and the Apostle Paul, as written in God's Word. Keeping them builds the score.
Practices the Lord and his apostle named and warned against. Where a tradition holds them as doctrine, the score drains; these are the things that lead a people away, not toward.
The KJB Adherence Index is an interactive study tool that measures how closely sixteen Christian traditions align with the doctrinal teachings and plain truth of the King James Bible. Fourteen Protestant families, Roman Catholicism, and Eastern Orthodoxy are scored two ways: adherence to nine teachings drawn directly from the words of Jesus and the Apostle Paul (the authority of Scripture, salvation by grace through faith, baptism as the Book teaches, the Lord’s Supper as instituted, church offices and governance, worship in spirit and truth, prayer as Jesus taught, living Jesus’ moral teaching, and no additions to the gospel), and violation of nine counter-teachings that Christ and Paul explicitly warned against (images and idolatry, mediators other than Christ, seeking the dead and familiar spirits, vain repetitions, exalted titles, forbidding to marry, works-salvation, extra revelation, and merchandising the gospel). What a church keeps builds its score; what it practices against the Book drains it.
Every criterion is anchored to quoted KJB passages, and every score carries a one-line reasoning you can inspect. Click any tradition for its full verse-by-verse breakdown, including the English translation that most closely fits its doctrine. An optional Advanced panel lets you reweight the criteria and set how heavily violations count, with the ranking recomputing live, so the conclusions are transparent and testable rather than fixed.
A second view, the Douay-Rheims Index, holds the same sixteen traditions to the Catholic Church’s own English Bible: the Rheims New Testament of 1582 and the Douay Old Testament of 1609–1610, revised by Bishop Richard Challoner, seventy-three books with the deuterocanon included. Every criterion is re-anchored to the Douay’s own wording, and rescored wherever its extra books speak. The result is the sharpest argument on the page: measured by its own Bible, Rome roughly doubles its score, and still finishes last. The order of the ranking barely moves at all. The gap was never between Rome and a Protestant translation; it is between Rome and any Bible, including its own.
The purpose is not to judge hearts, which no chart can weigh, but to put every tradition’s documented doctrine and observable practice beside the plain text of God’s Word and let the Book do the measuring.
