[6] It was during Devasahayam's tenure at the University that ecumenism gave way to merger of seminaries and the formation of special purpose entities throughout India.
It was Devasahayam who gave the inaugural address when the Andhra Christian Theological College was formed in 1964 in Rajahmundry.
[7] After scholastic studies at the CBM-McLaurin High School in Kakinada, Devasahayam enrolled for graduate studies from 1931–1933[2] at the Pithapuram Rajah College in Kakinada from where he obtained a degree in Sciences leading to the award of Bachelor of Science (BSc) by the Andhra University.
After Devasahayam's ministerial studies at Serampore College, he was assigned pastoral roles in rural areas where there were hardly any Christians and much like the Baptist heritage, he was left to himself to build up congregations.
At the height of the World War II, Devasahayam was asked to serve in the Royal Indian Navy as a Military Chaplain.
