Eliyahu said:
We do not have much resource to support the earlist time of acceptance for the NT, but simply we can wonder what was the canon of the NT during 100-350AD.
I believe there could have been minor controversy about the NT canon, about the epistles of James or Jude. As for others, I can easily believe they were well accepted and well defined immediately, especially during the time of Persecution by Roman Empire.
As for Sinaiticus, only the people who have never compared to other texts can consider it as a text. In fact it was a garbage, an antique garbage.
It starts from Salomon for Solomon ( in Mat 1), then Mt 6:28 says ?? ???????( not strange) ????????? ( ?????????) ( grow)
What a difference !
There are hundreds of spots where Aleph differs from majority texts. This can be a good treatise for the Doctors.
Leaving aside Sinaiticus, there is enough historical evidence to state the following regarding the NT canon before Athansius, in 367, was the first to list
exactly the same 27 books in the NT we have to day:
(1)First, the Four Gospels and Paul's Epistles were both circulating as units probably by mid-second century at the latest, and were the earliest widely accepted "core" of the canon.
(2)Second,
Acts (since it was associated with Luke and Paul),
1 Peter, and
1 John were also very widely accepted by the end of the second century
(3)Next, the following 7 books were in dispute in parts of the Church up until the mid to late 4th century:
Hebrews
James
Jude
2 Peter
2 & 3 John
Revelation
Again, Athanasius's letter in 367 and the Councils of Hippo (393) and Carthage (397) seem to have been the key factors in
officially finalizing the closing of the canon.
(4)Last, the following books seemed to enjoy a
measure of
local canonicity in certain areas for a while before ultimately being left out of the final "universal" canon:
1 Clement
Shepherd of Hermas
Epistle of Barnabas
Didache
Apocalypse of Peter
(and possibly
Gospel of Hebrews)
