Cristina Arámbulo Villanueva Manalo (born February 1, 1937, in Manila, Philippines), popularly known as Ka Tenny Manalo, is the widow of former Iglesia ni Cristo (INC) executive minister Eraño G. Manalo. She stood a loyal wife beside her husband who led the church for over 46 years, from the death of Felix Manalo in 1963 and until the latter's death in 2009. Her eldest son, Eduardo V. Manalo, who was at the time deputy executive minister, assumed the post seven days after his predecessor's demise.In the midst of the INC leadership controversy in 2015, Tenny was excommunicated (expelled). It was announced through circulars on regular worship services of July 23 to 25, signed by INC Secretary-General Radel G. Cortez with the approval of Executive Minister Eduardo Manalo. Lolita "Lottie" Manalo-Hemedez, Felix Nathaniel "Angel" Manalo and Marco Eraño Manalo were also expelled on the grounds of violating the doctrine on unity, INC's 22nd principal doctrine.
