The history of the Christian church is a fascinating story. Since the ascension of Jesus and the birth of the church at Pentecost, the followers of Christ have experienced persecution and martyrdom, established orthodoxy and orthopraxy, endured internal division and social upheaval, and sought to proclaim the good news "to the end of the earth." How can we possibly begin to grasp the complexity of the church's story? In this brief volume, historian Jennifer Woodruff Tait provides a primer using seven sentences to introduce readers to the sweeping scope of church history. Among the sentences: "No one whatsoever should be denied the opportunity to give his heart to the observance of the Christian religion." -The Edict of Milan (AD 313) "Light from Light, true God from true God, begotten not made, of one substance from the Father." -The Nicene Creed (325) "When our Lord and Master Jesus Christ said, 'Repent,' he willed the entire life of believers to be one of repentance." -Martin Luther's Ninety-Five Theses (1517) "The church is confronted today, as in no preceding generation, with a literally worldwide opportunity to make Christ known." -The Edinburgh Conference (1910) Pick up and read. The story continues. The accessible primers in the Introductions in Seven Sentences collection act as brief introductions to an academic field, with simple organization: seven key sentences that give readers a birds-eye view of an entire discipline.

Many congregations today are beset by fears, whether over loss of members and money, or of irrelevancy in an increasingly pluralistic society. To counter this, many congregations focus on strategy and purposewhat churches "do"but Cheryl Peterson submits that mainline churches need to focus instead on "what" or "who" they areto reclaim a theological, rather than sociological, understanding of themselves. To do this, she places the questions of the church's identity and mission into a conversation with the primary ecclesiological paradigms of the past century: the neo-Reformation concept of the church as a "word event" and the ecumenical paradigms of the church as "communion." She argues that these two paradigms assume a context of cultural Christendom that no longer existsfocused on the church that is gatheredrather than the missional church that is sent out. Peterson suggests instead that we understand the church as a people created by the Spirit to be a community, and that we must claim a narrative method to explore the church's identityspecifically, the story of the church's origin in the Acts of the Apostles. Finally, here is a way of thinking of church that reconciles the best of competing models of church for the future of mainline Protestant theology.

Constantine the Great is one of those rare historical figures who is nearly as controversial today as he was in his own time. Lauded, both then and now, as a military hero who ended the brutal persecutions of Christians and as the first Roman emperor to himself embrace Christianity, Constantine is just as often vilified as a destructive innovator, a coddler of heretics, and a tyrannical hypocrite with the blood of his own family on his hands. The Life of the Blessed Emperor Constantine was penned shortly after the emperor's death in AD 337 by the great Church historian Eusebius Pamphilus, bishop of C]sarea. Though criticized as mere panegyric lionizing Constantine's virtues while ignoring his flaws, Eusebius's Life is nonetheless the most substantial and detailed biography of the first Christian emperor to come down to us from antiquity. The work is also the sole source for several key episodes in Constantine's life--including the emperor's famous vision of a cross in the sky accompanied by the words, "Conquer by this."
