Upon his return home in February 1910, Rachmaninoff became vice president of the Imperial Russian Musical Society, whose president was a member of the royal family. Later in 1910, Rachmaninoff completed his choral work "Liturgy of St. John Chrysostom" (Op. 31), but it was banned from performance as it did not follow the format of a typical liturgical church service. For two seasons between 1911 and 1913, Rachmaninoff was appointed permanent conductor of the Philharmonic Society of Moscow; he helped raise its profile and increase audience numbers and receipts. In 1912, Rachmaninoff left the IRMS when he learned that a musician in an administrative post was dismissed for being Jewish.
