A profound exploration of human ensoulment and personhood at the moment of conception, this bioethical and theological work reveals how the mystery of Christ's incarnation as a one-cell zygote, from the first instant of His conception, can advance and illuminate the mystery of man. Drawing from Scripture, Tradition, Church documents, science, philosophy, and theology, The Zygote of Christ & The Mystery of Man defends human conception and embryonic life as an icon of the Mystery of God's Creation and the Mystery of the Incarnation of Christ, emphasizing man's (male and female) personal and relational identity with the Blessed Trinity as well as the mysterious co-participation of man (male and female) in God's creative love at the conception of every human person.
