A nicodemite, usually a term of disparagement, is a person who is suspected of public misrepresentation of their actual religious beliefs by exhibiting false appearance and concealing true beliefs.
Introduced into 16th century religious discourse, its currency persisted into the 18th century and beyond. It was usually applied to persons of publicly conservative religious position and practice who were thought to be secretly humanistic or reformed. Originally employed mostly by Protestants, it was also later used by Catholics as well.
Friedrich Heer in his book The Medieval World refers to the 12th century circle at Chartres as past masters of Nicodemism which he describes as "dangerous thoughts, dangerous allusions to topical ecclesiastical and political affairs, and above all to ideas hard or impossible to reconcile with the dogma of the Church or the maxims of the prevailing theology".
The term was apparently introduced by John Calvin (1509–1564) in 1544 in his Excuse à messieurs les Nicodemites. Since the French monarchy had increased its prosecution of heresy with the Edict of Fontainebleau (1540), it had become increasingly dangerous to profess dissident belief publicly, and refuge was being sought in emulating Nicodemus.
In the Gospel of John (John 3:1-2) there appears the character Nicodemus, a Pharisee and member of the Sanhedrin. Although outwardly remaining a pious Jew, he comes to Jesus secretly by night to receive instruction. Although he was eventually made a saint, his dual allegiance was somewhat suspect.
There was a man of the Pharisees, named Nicodemus, a ruler of the Jews: The same came to Jesus by night, and said unto him, Rabbi, we know that thou art a teacher come from God: for no man can do these miracles that thou doest, except God be with him.
