In this chapter the author explores the role of poetry and sermons in propagating Tractarian theological ideas. The use of these two distinct genres was closely connected to the principle of reserve, a theory of knowledge holding that religious truth ought to be conveyed in accordance with the recipient’s ability to receive it. While poetry allowed a more detailed theological reflection, sermons offered a better opportunity for practical teaching. The chapter examines how the Tractarians used these genres to deal with the interpretation of Scripture, the relationship between Church and state, apostolic succession and the sacraments of baptism and the eucharist.
