Now, the beauty in all this is that the words Cranmer originally wrote are doctrinally rich, profound words, closely drawn from Scripture, and worthy of being memorised. Much of the liturgy actually is Scripture, and because it is repeated often, it has been stored up in the hearts of Anglicans for centuries. For instance, the weekly reminder to Let your light so shine before men, that they may see your good works and glorify your Father, who is in heaven has been an inspiration to live openly as a Christian, especially in times of difficulty, so that others may glorify God the Father. The prayers of confession are articulate, graceful statements of true teaching. Such prayer, if taken to heart by frequent use, is an inestimable blessing.
Memorised truths become an almost unconscious prompt to righteous responses.
Another part of the Prayer Book heritage has been the regular singing of psalms to chants. In the 1970s, it certainly was not the coolest thing you ever did, to sing the psalms to 17th and 18th century English chant tunes. However, chapel services had us chanting psalms daily, and we grew to love this form of singing. To this day I still remember parts of psalms and even whole psalms because of these chants. Well, I am not advocating the use of the Book of Common Prayer in our worship services.
