The Greek text is preserved in more than 5,800 manuscripts, exceeding other ancient writings in manuscript count. 2nd-3rd century papyri like P46, P66, P75 provide text roughly 100-150 years after composition. Major uncial codices (Sinaiticus, Vaticanus, 4th century) contain complete or near-complete texts. The Byzantine text family represents the majority of later manuscripts. Textual variants exist but are mostly minor: word order, articles, spelling. No central Christian doctrine depends on any disputed text. Modern critical editions compare all manuscript families to determine the most likely original reading.
