The logo of the Church of South India consists of a cross superimposed on a stylized Lotus flower in a white backdrop; around which the motto and name of the Church, is embossed. It was designed by Prof. J. Vasanthan of the American College, Madurai, India.

The imposing central position of the Cross denotes the foundation of the Church and its faith, while its four arms of the same length promulgates equality. The lotus flower, called Pankaj meaning “mud-born” in Sanskrit, has been of great spiritual and symbolic significance in India, since ancient times.

Its placement in the Logo, proclaims the indigenous nature of the Church of South India and its dependence on the Grace of God, just as a Lotus that blooms at sunrise and closes at sunset, depends on the sun. The stylized rendering makes the lotus petals simultaneously depict the fiery split tongues of the Holy Spirit. The motto of the CSI embossed on the logo, which is an excerpt of Jesus’s prayer in John 17:21, is used as an inclusive affirmation of the need for the unity of all people.
