Marriage and Sexuality in Early Christianity is part of Ad Fontes: Early Christian Sources, a series designed to present ancient Christian texts essential to an understanding of Christian theology, ecclesiology, and practice. The books in the series make the wealth of early Christian thought available to new generations of students of theology and provide a valuable resource for the church. Developed in light of recent patristic scholarship, the volumes provide a representative sampling of theological contributions from both East and West.

The series provides volumes that are relevant for a variety of courses: from introduction to theology to classes on doctrine and the development of Christian thought. The goal of each volume is not to be exhaustive but rather to be representative enough to denote for a nonspecialist audience the multivalent character of early Christian thought, allowing readers to see how and why early Christian doctrine and practice developed the way it did.
