Emperors grant peace, and the church fights over Christ

Piero della Francesca, about 1452–1466, Arezzo. Constantine’s dream before the battle of AD 312.
What Christians endured, taught, and practiced
Was the Son created? What makes a sacrament valid?
Emperors call bishops together, and their verdicts differ
Teachers and preachers who shaped the church
Empire, borders, and the Goths
What the Lutheran Confessions say about this century
Why does the Son’s full deity matter for his saving work?
