The fourth century was a period of monumental transformation for the Christian faith, as it moved from the margins to the centre of public life. G. Hellemo's 'Adventus Domini' invites you to look closely at this era through the dual lenses of architectural apses and formal catechetical instruction. By investigating the 'Adventus'—or the coming of the Lord—as a central theme in both visual art and church teaching, this book reveals how the early church conceptualised their eschatological hope. You will gain a unique perspective on how 4th-century believers expressed their faith in the imminent return of Christ through the physical spaces they built and the lessons they taught. This work is ideal for students of church history and art history, offering a vivid portrait of an age that was deeply preoccupied with the final victory of God. Explore the ways that hope for the future shaped the daily worship and spiritual devotion of the ancient church in a way that remains relevant to your own understanding of faith today.
