1.) Edmund White (2009). Marcel Proust: A Life. Penguin. ISBN 9780143114987. "Marcel Proust was the son of a Christian father and a Jewish mother. He himself was baptized (on August 5, 1871, at the church of Saint-Louis d'Antin) and later confirmed as a Catholic, but he never practiced that faith and as an adult could best be described as a mystical atheist, someone imbued with spirituality who nonetheless did not believe in a personal God, much less in a savior."
2.) Proust, Marcel (1999). The Oxford dictionary of quotations. Oxford University Press. p. 594. ISBN 978-0-19-860173-9. "...the highest praise of God consists in the denial of him by the atheist who finds creation so perfect that it can dispense with a creator."
