  • Evangelism in Ghana — The Presbyterian Church of Ghana: 1942 – 1954

    First published in Twi in 1965

    Author’s note about the Book

    This book is the translation of an account of the last 12 years of the work of my father, the Rev. Emmanuel Victor Asihene in the Presbyterian Church of Ghana.

    It refers to his work as the First Evangelist Minister appointed by the Church at a critical time in its history. He wrote the book deliberately in Twi to make the story of the Evangelism Mission that he undertook readily accessible to all members of the Church.

    He was grateful to be assigned to carry out the Mission of Evangelism. In his own words, he explains:

    “On the day of my ordination in 1960, this verse, ‘I will tell of thy name to my brethren; in the midst of the congregation, I shall praise you,’ Psalm 22, verse 22 was my major vow and promise. With great joy therefore, I thank God that I have been chosen and given the chance to spread the word of the Lord, through Evangelism, here , in my own land, and among my own people.”

    At the time of his appointment, he had no doubt that “what was needed most was the grace and guidance of God and a great infusion with a personal spiritual strength.”

    The journeys that Rev. Asihene made, most of them on foot, to distant areas of the country were extensive — as can be seen from the list of places that he visited.

    Many of the difficult-to-read areas where he took the message of God are, even today, not readily identified on the map of Ghana. Accounts of his easy engagements with Church members, non-Christians and even with fetish priests are as fascinating as the return of backsliders, by the grace of God, into the Church.

    When I received and read my signed copy of the book 47 years ago in 1965, I knew that I would one day translate this unique record of extensive Evangelism by a local member of the Presbyterian Church in our own country, from Twi into a wider read language. I am glad and I consider it a great honour that I have been able to translate, into English, this important piece of history of the Presbyterian Church of Ghana.

    During this 125th Anniversary of his birth, this Translation of this book also marks the Dedication of the commemorative building, “The Rev. E.V. Asihene Quiet Room” at the Anum Presbyterian Secondary School, where he was Headmaster, about 90 years ago.
