Apostolic Succession Decoder
Five major Christian traditions claim continuity with the apostles. They do not all mean the same thing by succession. 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 Sabbath obligation; Sunday is the obligatory day | Yes (Vespers, fasting prohibited, full Liturgy in monasteries) | 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 (rejected as canon in the Reformation; often omitted from printings by the nineteenth century) |
| Developments this study questions | Filioque, Sunday obligation, Vatican I papal definitions | No comparable changes argued here | No comparable changes argued here | Inherited some Western changes | Reformation canon boundaries, retained Sunday practice |
| 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) | Disputed; institutional form dates to the Reformation, and patristic continuity claims are contested | 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 parishes), full Liturgy (monasteries, Lent, feasts) | Ethiopian Tewahedo (36M+) | None institutionally | SDA (22M), 7th Day Baptist, COG7 |
What the Comparison Reveals
By this study’s criteria, Eastern Orthodox and Oriental Orthodox claims score highly because they preserve the original Nicene Creed, give Saturday a continuing liturgical place, and receive deuterocanonical books within ancient ecclesial tradition. Other communion claims remain weighty. This comparison marks where this book sees later developments, including the filioque, Sunday obligation, Vatican I papal definitions, and Reformation-era canon boundaries.
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.
