Hi, Fitzy and welcome
The most reliable manuscripts that exist today are the Massoretic manuscripts 900AD(OT manuscripts), Dead Sea Scrolls 150BC-70AD(OT manuscripts), Codex Vaticanus 325-450AD(greek NT manuscripts), and Codex Siniaticus 325-450AD(greek NT manuscripts).
Aleph (Sinaiticus) and B(Vaticanus) were exploded as accurate manuscripts as long ago as 1883(The Revision Revised--John Burgon)and have had a demolition job up to the present. WH`s axioms of older,shorter,harder and their Genealogical methods have been exposed as nonsense.
If you have an inerrant manuscript, trot it out and let`s see.
