As you explore the Christian faith, you will soon encounter some challenging words: Trinity, Sacrament, Reconciliation, Sin, Incarnation, even the word 'Christ' itself. It isn't Jesus's surname! It is a title with a meaning and history. Sooner, or later, these words, and the ideas behind them, must be addressed and understood. It is simply not possible to be a Christian without understanding sin and forgiveness, knowing what a sacrament is, or accepting Jesus as the Christ. This book is here to help. It explores and explains many of the key concepts and ideas that underpin the Christian faith. "I had assumed that someone else had already written a book like this. It seemed such an obvious thing to do. But while I could find weighty tomes on the topics explored here, I couldn't find a book which covered all these things in ways that were accessible, comprehensive and friendly: a simple book about complex things, one which just about anyone could read and find helpful. So, I wrote one." - Archbishop Stephen Cottrell
