The Books of Ephesians and Colossians were never disputed.
By 100AD, all 27 books of the New Testament were in circulation and all but Hebrews, 2 Peter, James, 2 Jn, 3 Jn, Revelation were universally accepted. http://www.bible.ca/b-canon-earliest-evidence.htm
There is no transcription error, the blood is in Col.1:14 Not in most Greek sources.
Well, there are a number of correct readings that are left out in the Majority of Greek sources, like Acts 8:37, 1Jn.5:7.
Sometimes the Old Latin and other translations show the correct reading instead of the Greek.
No, without blood the verse is in error and there cannot be errors in the Bible text, if it is to be considered the Bible Well, I got news for you: try reading more than one version of the dozens and dozens of redacted and edited versions of the Bible and you would be amazed what's in them or what's not in them all!
And why would I want to read a bunch of corrupted bibles?
I've got news for you, read the King James, believe it and get saved!
Or you can just stay where you are. There is some comfort in denial. BTW, shhh, the earth is really not flat.
And your works cannot save you (Eph.2:8, Gal.2:16)
I don't want to watste my time with you. You can live in denial, if you so choose. However, the authorship of the Ephesians and Colossians is disputed. And so is the authorship of most NT books.
