Soulen’s chapter can be summarized in his own words:
Barth challenged Christians to speak of the mystery of eternal generation in every available way. I have proposed that in practice this means cultivating three patterns of scriptural speech: one that emphasizes the First Person and the mystery of divine uniqueness at the source of the triune life; one that emphasizes the Second Person and the mystery of divine copresence at the heart of the Trinity; and one that emphasizes the Third Person and the mystery of connection mutual blessing that glorifies the Trinity in eternity and time. My hope is that by cultivating these three forms of speech Christians might speak of the mystery of eternal generation—not adequately, but perhaps a little less inadequately. (146)
