A former university professor who authored books for Christians about the ethics of marriage and sexuality has been arrested for raping a child, Us Weekly has learned. John Kent Tarwater was once a finance professor at Cedarville University, a Baptist school in Ohio. Tarwater, 55, is facing eight sex-based felonies stemming from allegations made by the minor victim. He was formally charged on March 27 with two counts of rape, three counts of sexual battery and three counts of gross sexual imposition.
