Dr Blamires, who counted CS Lewis among his friends and wrote 'The Christian Mind' in 1963, wrote 30 books in his lifetime.
Colin Hart, Director of The Christian Institute, said: "We thank God for the life of Dr Harry Blamires, he was a huge influence on many Christians through his writing.
"Perhaps the greatest tribute that can be paid to him is to say that he has helped thousands of Christians recover the Christian mind.
"He was an inspiration in the founding of The Christian Institute, giving some of the first ever Christian Institute lectures, and he continues to be an inspiration to our staff."
Dr Blamires was born in 1916 and studied English at the University of Oxford under CS Lewis.
The two Christian authors became close friends and Dr Blamires' work was greatly influenced by Lewis.
John Burn, Chairman of The Christian Institute, said: "The Christian Mind and The Post-Christian Mind transformed my thinking.
"They exposed the way in which Christians so easily are influenced by secular humanism rather than by the Bible."
Dr Blamires later became the Dean of Arts and Sciences at King Alfred's College, which is now the University of Winchester.
His 30 books include novels, literary criticism and Christian apologetics.
He was married to Nancy who died in 2011 and they had five sons.
Dr Blamires' funeral will be held at St John's Church, Keswick on 30th November 2017 at 1.30 pm.
