The first part discusses the nature and method of Christian theology, human mobility as a permanent feature of Human existence, the categories of migrants and types of migration, and the intrinsic relations between migration and religion, especially Christianity. The second part presents a new theology of God: God the Father is the Primordial Migrant, God the Son the Paradigmatic Migrant, and God the Holy Spirit the Personal Power of Migration.
