In this vigorous defense of Catholic teaching, Dr. Peter Kwasniewski draws on Scripture, tradition, and voices both ancient and modern to illuminate the sacred meaning of matrimony, priesthood, and religious life. He explores the nobility of marriage, the spiritual symbolism of sexuality, and the lessons found in the Holy Family, while also offering a thoughtful treatment of priestly celibacy and the vocation to consecrated life. Confronting contemporary distortions of love and the human body, he presents a vision in which chaste, fruitful self-gift reflects divine wisdom. Rooted in faith and reason, this work renews confidence in the Church’s teaching on vocation and the sacramental dignity of love.
