Since the funds for that transept were donated solely by women, it was called the Women's Transept. Work on the Women's Transept was halted in October 1930 due to a lack of funds. Construction at St. John's was otherwise unaffected by the Great Depression. During this duration, work was concentrated mainly on the western elevation. When construction of the Women's Transept resumed in 1934, the nave and the western elevation were nearly complete except for the two towers above the western facade, but work on the crossing tower and south transept had yet to commence. By 1938, the nave was completed, but the temporary construction wall between the nave and crossing was still in place because the Byzantine-Romanesque crossing's design had yet to be harmonized with the Gothic nave. As such, Cram subsequently replaced the portions of the ceiling above the choir and the apse's eastern section. Additionally, the nave started to be used for services, even though it had not yet been dedicated. The 1939 WPA Guide to New York City stated that $20 million had been spent on the cathedral by then. Full-length opening and expansion The full length of the Cathedral of St. John the Divine was opened for the first time on November 30, 1941. At that time, St. John's was only three-fifths completed, yet it was the second-largest Christian church in the world by area, behind only St. Peter's Basilica in Vatican City. The event was commemorated with a week-long celebration. The last day of the celebrations, Sunday December 7, 1941, coincided with the Japan's attack on Pearl Harbor. With the consequent entry of the United States into World War II, work on the cathedral stopped. The southern transept and tower had yet to start, while the northern transept remained one-third complete. The western towers, planned to be , reached only to the roof of the nave. Cram revised his plans yet again just before his 1942 death, this time with shorter western towers and a slim spire in place of the square tower over the crossing. Halt in construction Following the end of World War II, St. John's did not experience any more new construction for three decades. In 1945, Manning had attempted to start a fundraising drive for $10 million so that the remaining funds could be raised for the cathedral's completion. However, during the late 1940s, his successor Bishop Charles Kendall Gilbert
