The Greek text is preserved in 5,800+ manuscripts, surpassing other ancient works in manuscript count. Early papyri from the 2nd-3rd centuries like P46, P66, P75 provide text within about 100-150 years of its writing. 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.
