What's the big deal about baptism? Jesus commands his disciples to be baptized, and it's a glorious picture of a person's union with Jesus' death, burial, and resurrection. Still, many Christians feel unclear about the topic, having more questions than answers. This short work provides a biblical explanation of baptism. What is it? Who should be baptized? Why is it required for church membership? And how should churches practice baptism?

A seminal figure in late antique Christianity and Christian orthodoxy, Saint Gregory of Nazianzus published a collection of more than 240 letters. Whereas these letters have often been cast aside as readers turn to his theological orations or autobiographical poetry for insight into his life, thought, and times, Self-Portrait in Three Colors focuses squarely on them, building a provocative case that the finalized collection constitutes not an epistolary archive but an autobiography in epistolary form-a single text composed to secure his status among provincial contemporaries and later generations. Shedding light on late-ancient letter writing, fourth-century Christian intelligentsia, Christianity and classical culture, and the Christianization of Roman society, these letters offer a fascinating and unique view of Gregory's life, engagement with literary culture, and leadership in the church. As a single unit, this autobiographical epistolary collection proved a powerful tool in Gregory's attempts to govern the contours of his authorial image as well as his provincial and ecclesiastical legacy.
