Apostolic Succession Decoder

Five major Christian traditions claim continuity with the apostles. Their claims differ in kind, scope, and evidence. This study compares them on ten dimensions that matter for the Sabbath question.

Dimension Catholic Eastern Orthodox Oriental Orthodox Anglican Protestant
Claims unbroken episcopal succession Yes Yes Yes Disputed No
Rome recognizes their orders Yes Yes Yes No (Apostolicae Curae, 1896) No
Preserves original Nicene Creed No (added filioque 1014) Yes Yes No (follows Roman filioque) Varies by denomination
Saturday retains liturgical status No (fully replaced by Sunday) Yes (Saturday Vespers, no fasting) Yes (Ethiopian Saturday liturgy) No SDA, 7th Day Baptist keep Saturday
Accepts deuterocanonical books Yes (Trent 1546) Yes (anagignoskomena) Yes (broadest canon, 81 books) In lectionary, not doctrine No (removed 19th century)

Conscious intermediate state Yes (plus purgatory) Yes (toll houses debated) Yes Yes Varies (SDA teaches soul sleep)
Pre-Nicene Fathers support their position Partially (papal primacy debated) Yes (conciliar model matches) Yes (miaphysite Christology from Cyril) No (did not exist before 16th c.) No (Sola Scriptura is post-Reformation)
Number of adherents (approx.) 1.3 billion 220 million 60 million 85 million 900 million
Sabbath-keeping members None institutionally Saturday Vespers (all), Ethiopian Saturday liturgy (36M+) Ethiopian Tewahedo (36M+) None institutionally SDA (22M), 7th Day Baptist, COG7

What the Comparison Reveals

The Eastern Orthodox and Oriental Orthodox traditions are the only ones that preserved the original Nicene Creed, maintained Saturday's liturgical status, accepted the deuterocanonical books from antiquity (not from a Counter-Reformation vote), and made no unilateral changes to the apostolic faith. The Catholic Church has apostolic succession but altered the Creed, the day, and the canon. Protestantism recovered Sola Scriptura but lost the Sabbath, the deuterocanon, and continuity with the pre-Nicene Fathers.

The Ethiopian Orthodox Tewahedo Church, part of the Oriental Orthodox family, combines apostolic succession, the original Creed, the broadest canon (including Jubilees and 1 Enoch), and 1,600 years of Saturday worship. No other tradition holds all four.
