Sexuality is not what we do but who we are. My generation has neglected to pass on this timeless truth. There are truths that are certain, guaranteed and timeless; that is, they have no expiry date. Such truths would normally have been passed on from one generation to the other, from parents to children. Somewhat like a baton is passed on in a relay. Tragically these truths have been lost amid a sea of humanism and materialism. One truth that gives peace to the mind, health to the body and joy to the heart, in need of being rediscovered, is the power of purity. It connects and provides personal harmony and fulfilment to the body, heart and mind. This short book is an attempt to exemplify the beauty and meaning of purity. Young people will find this book to be of great value! A book that successfully challenges young people to seek out what is authentic in human relationships. It is concise, and yet its content is comprehensive and covers the Church's teaching in a clear and uplifting way. Very readable and very practical in this delicate domain, it can be recommended without hesitation to youth to answer all their questions, as well as to those discerning their vocation. The common sense approach highlights the many pitfalls evident in the prevailing culture and reveals a way ahead - drawing on the profound moral wisdom of the Church. In an age which sees sex not as an icon but an idol Fr Murphy offers much to help the reader see what purity consists of in a holistic way and how it can be attained. Since his book contains good analogies and language that is accessible to youth, it easy to read.
