[10] In May 1998, Sam U. Erivwo wrote that Cornelius Adam Igbudu was held "in very high regard" by Bishop Agori Iwe, his contemporary.
[11] Igbudu was also remembered for his remarkable contribution to the spread of Christianity in Nigeria through the Anglican Adam Preaching Society.
[17] He became a force to reckon with, carried out his evangelistic activities outside the Church and successfully made many people to accept the Christian faith.
[13][17] He was credited with revolutionizing the Anglican Church of Nigeria by introducing indigenous gospel songs that appeal to the spirituality of the Isoko people in the Niger Delta region.
[19] Cornelius Adam Igbudu died aged 67 on 12 March 1981 and was buried at his compound at Araya on 4 April 1981.
