The apocryphal (from the Greek apokryphos meaning
hidden)
books have multiple meanings:
complimentary meaning - that the sacred books were
too
exalted for the general public;
pejorative meaning - that the orthodoxy of the books
were
questioned;
heretical meaning - that the books were forbidden
to
be read; and lastly
neutral
meaning - simply noncanonical books, the
meaning
the word has today.
Another word, pseudepigrapha (from the Greek meaning
false writing) is used for works clearly considered
to be false.
