A self-professed life-long devotee of the Prayer Book, Dodd described it as "beautifully-written".
Deeply rooted in the Bible, The Book of Common Prayer was created in 1549 as the traditional service book of the Church of England.
However, its 1662 revised version remains in use today as written by its author, Thomas Cranmer.
Sir Ken says he fondly remembers it from his choir days at the Church of St John the Evangelist in Knotty Ash in Liverpool and says it is, "in many ways, very up-to-date".
The 89-year-old says while he enjoys the traditional language of the book - he would like to see it modernised so younger people can connect with it.
He thinks a combination of both, could be just what it needs, stating it would mean, "more to those struggling to cope with some of life's most basic problems, like keeping up with payments on the mortgage or the car, or coping with the care of sick children."
Nevertheless, he admits it would be a challenge for anyone to update a book that old.
Ken Dodd was given his knighthood earlier this year for services to entertainment and charity.
