8Written as a challenge to Christian churches' rigid focus on doctrine and practice, Rainbows & Windmills offers an introduction to personal spirituality.

Framed through Peter Tarleton Stewart's personal childhood experiences, he advises how to strengthen faith in the 21st century. The author expresses the importance of church institutions unburdening themselves of out-of-date and unsubstantiated material. Only then can they offer a 'pilgrim' model of spirituality to those who have persisted in membership despite the misleading and unscientific positions taken by leaders in recent decades.

Peter Tarleton Stewart encourages us to begin that reformation on a personal level. This means that we develop a mature spirituality which recognizes our worthiness to share with others the privilege of an earthly life, and the reality of a divine spirit.
