Oneness introduces Jesus' vision of deep union between husband and wife—a vision that can become a guiding light for every couple working through issues and trying to deepen their love for each other.

The book begins with the words of Jesus, moves backward and forward in the Bible from Genesis to Ephesians, and expands outward to explore the mysteries of marriage like friendship, mutual subordination, sexuality and loving cooperation. What does it mean to become one in marriage? What are the paths to this sometimes seemingly distant goal? To answer these questions, the Perrottas combine a careful, practical, and at times moving exploration of the biblical foundations of Christian marriage with helpful and humorous insights from their own improbable union. Their experiences and those of other couples highlight the joys, struggles, and surprises of Christ’s call to discipleship within marriage, letting readers see the blessings and challenges of this wonderful vocation—and the divine help available for it.

A study guide, “Pray, Talk, Act,” helps readers use the book to probe their own marriage and consider the value and implications of Jesus vision of marriage for themselves. The questions aid readers in seeing how Jesus’ vision of oneness can become a reality in their own lives.

For any couple wanting to focus on their relationship, Oneness provides help for exploring vision and goals and examining the texture of their relationship. And the book can of practical interest also to who are engaged or anyone thinking of marriage. Those who counsel married couples or mentor the engaged will find Oneness a thought provoking resource.

Written from the Catholic perspective, Oneness is for all Christians.
