Evangelii Gaudium §157

157. Simply using a few examples, let us recall some practical resources which can enrich our preaching and make it more attractive. One of the most important things is to learn how to use images in preaching, how to appeal to imagery. Sometimes examples are used to clarify a certain point, but these examples usually appeal only to the mind; images, on the other hand, help people better to appreciate and accept the message we wish to communicate. An attractive image makes the message seem familiar, close to home, practical and related to everyday life. A successful image can make people savour the message, awaken a desire and move the will towards the Gospel. A good homily, an old teacher once told me, should have “an idea, a sentiment, an image.”
