Born on 26 August 1936 in Idua Eket, Eket Local Government Area of Akwa Ibom State, the departed cleric was a man of many firsts.
He was the first black president of the World Methodist Council. He was also the first Methodist President of CAN. First Patriarch's Chaplain and Bishop of Tinubu and the only person to have held the position of both patriarch and prelate.
Mr Mbang's ministerial work spanned over four decades, having enrolled at the Trinity College, Umuahia, Abia State, in 1962.
He rose through the ranks to become the Bishop of Tinubu, Lagos State, in 1979. He was later elevated to a Patriarch/Prelate - the administrative and pastoral leader of the Methodist Church in Nigeria, a position he served for 22 years.
The late prelate had his primary school education at Salvation Army School, Akai Ubium, Eket and Methodist Boys High School, Oron, Oron Local Government Area, Akwa Ibom State, for his secondary education.
He attended the Trinity Theological College, Umuahia, in Abia State, for pastoral training. He further studied at the University of Ibadan, Hebrew University of Jerusalem, Israel and Harvard University in the United States of America.

In recognition of his leadership, the Methodist Church Nigeria named one of its dioceses Mbang's Cathedral in Eket, Akwa Ibom State, in his honour.
'He stood for what was right' - Peter Obi
Peter Obi, the presidential candidate of the Labour Party in the 2023 election, in his reaction to his passing, described Mr Mbang as a "man known to be sincere in words and actions".
Mr Obi said he met with Mr Mbang in Uyo last December and that the cleric told him that "God would use me to save Nigeria".
"As a Prelate, he was one of the most patriotic Nigerians, who not only stood for what is right but also spoke truth to power without fear or favour. In my own case, when I was rigged out in the Anambra Gubernatorial election in 2003, he was the first clergyman to publicly tell the President then, Chief Olusegun Obasanjo, that I won that election," Mr Obi said.
"The nation needs his prayers now more than ever. He truly loved Nigeria. I send my heartfelt condolences to the Mbang family, the Methodist Church of Nigeria and the nation in general on the death of this patriotic Nigerian who lived an exemplary life.
"May God grant him eternal rest and comfort all who mourn him," he added.
