Why ''Saint René Descartes'':
On November 28, 2007, the Cesidian Church beatified René Descartes, and issued a " Saint René Descartes Declaration " urging support for his canonization. In response, several persons from various walks of life and different denominations, even an atheist, have signed the petition in favor of Descartes' canonization, and together with the bishop of the Cesidian Church, two bishops and one archbishop have expressed their favor for Descartes' sainthood.
Saint René Descartes was consecrated the First Saint of the Cesidian Church on December 13, 2007.
