Mr Rowlandson, who was a key figure in the life of the UK evangelical church over a number of decades, died on Thursday 13 August, two days before his 90th birthday.
He served as the Extensions Secretary at the Evangelical Alliance before being appointed to the team running Dr Billy Graham's first visit in England, in 1954.
During his time as Director of the Billy Graham Evangelistic Association UK he organised 23 major mission events in cities including Manchester, Glasgow, Belfast, London, Norwich, Blackpool and Sheffield.
His life will be celebrated at a service at Greyfriars Church, Reading, at 11am on 26 September.
Mr Rowlandson was said to have loved sailing and founded the Venturers Norfolk Broads Cruise, a week-long Christian sailing camp for young people.
Generations of teenagers have taken the part in the camp, which has now been running for 70 years.
He once contested a Parliamentary seat for the Liberal Party, in 1959, and was a magistrate for 27 years.
He leaves his wife Marilyn and two children, Julian and Jacky, as well as eight grandchildren and four great-grandchildren.
The family has asked for donations to his chosen charities.
