Trompée.
Votre religion a été trompée. You have been greatly imposed upon. Similarly, Suprendre la religion de quelquun is to deceive or impose upon one. Cardinal de Bonnechose used the former phrase in his letter to The Times respecting the Report of the cumenical Council, and it puzzled the English journals, but was explained by M. Notterelle. (See The Times, January 1st, 1870.)

We use the word faith both for credulity and religion e.g. Your faith (credulity) has been imposed upon. The Catholic faith, Mahometan faith, Brahminical faith, etc., virtually mean religion.
