This article explores resources within the Christian theological tradition that recognize happiness in earthly life while also preparing Christians for ultimate happiness through union with God. Two resources explored in the article are the appreciation of happiness in Jesus's ministry and its engagement with Greek philosophy. After exploring these resources, the article turns to Aelred of Rievaulx, the great medieval theologian, to investigate how moral virtue, transcendent happiness, and earthly pleasure are harmonious parts of a holistic Christian vision of happiness. Finally, after examining Aelred's contribution, the article considers how this integrated view of happiness can help us to think through the problems of happiness in our lives today.
