Sa Ngalan ng Diyos ("In the Name of God") is a Tagalog-language novel written in 1911 by Filipino author Faustino Aguilar. Controversially, it illustrated how greedy Jesuit priests schemed, manipulated, and took advantage of Carmen, a young, naive, pious, and affluent heiress. The 191-page book was published in Manila by the Limbagan at Aklatan Ni I.R. Morales (Printing Press and Library of I.R. Morales) during the American period in Philippine history (1898–1946).
