Just so everyone is clear (and you may already know this) but a Codex is not a “Bible” per se. It is a collection of texts bound together. Some of the contents may be “considered Scripture” (as the OP asked) and some may not. Some stuff might just be good for Catechesis or simply edifying reading or perhaps even historical reading. Codices really shouldn’t be considered strict examples of “what the Church considered Scripture.”
For instance, the
Codex Claromontanus which you mention above also includes 3rd Corinthians, Acts of Paul, and Revelation of Peter. From that we should not surmise that all these texts were once “considered Scripture.”
The
Codex Fuldensis contains the Epistle to the Laodiceans. From that we can neither surmise that this book was considered Scripture simply because it was found in a Codex with other texts that were Scripture.
By the same eye, we can look at the 10th/11th century
Codex Mediolanensis which only contains a few selections from Luke and Acts of the Apostles. From that we should not surmise that these are the only two inspired books the compilers believed were inspired. They are just the two books that they put in the Codex.
My point is that any single Codex is not necessarily a complete measure of what was “considered divinely inspired Scripture.”
