In an interview with Reuters, Rev Prof Kwabena Asamoah-Gyadu said that Ghana's 16 million Christians are shaping the future of the church on a global scale.
More than 70 per cent of Ghanaians consider themselves Christians according to the country's latest census.
European Catholic missionaries arrived in Ghana in the 15th century. According to the World Factbook, the majority of Ghanaian Christians now belong to Pentecostal or Charismatic churches.
Rev Asamoah-Gyadu added that the rise in Christianity in Africa has been predicted for decades.
"By the middle of the 20th century scholars ... started predicting that Africa (and Latin America) was going to be the hotbed of Christianity," he said..
"What happens in the minds of African Christians was going to shape church history for many years to come."
Yesterday, Moderator of the Church's General Assembly Dr Russell Barr called for African missionaries to share the gospel in the UK.
"You're faith has found it's African heart and soul and it's African voice. You need to teach us again how to find our Scottish heart, and soul and voice because your Church is growing and, sadly, our church is not," he told members of a church in Kikuyu, Kenya.
More than 40 per cent of the world's Protestants live in Africa, with the figure expected to rise to 53 per cent by 2050 according to the International Bulletin of Mission Research.
In contrast, the Office for National Statistics has reported that the proportion of the adult population in England and Wales describing themselves as 'Christian' declined from 67 per cent in 1983 to 41.7 per cent in 2014.
