“Take and Eat is a heart-stirring case for why we should consider gathering around the Lord’s table weekly. With a pastor’s care and a teacher’s clarity, Perkins walks us through Scripture to show how this spiritual meal isn’t just about ritual but a celebration of Christ’s grace that strengthens us for our sojourn.” – Patrick Abendroth, pastor, Omaha Bible Church

This book challenges common misconceptions, showing that repentance isn’t about earning God’s favor but experiencing the freedom Christ purchased. Rather than focusing on guilt, Perkins emphasizes how repentance allows believers to enjoy the ‘twofold benefit’ of Christ―justification and progressive sanctification.

“Harrison Perkins has written a significant book that not only presents a convincing account of Ussher’s theology but also offers clear instruction in how to distill and analyze complex and multi-language theological and historical sources. As scholars of early modern British religious history think about how to research and write in a more interdisciplinary manner, this study of James Ussher points a way forward.” – Bruce Gordan, Yale Divinity School, Church History (source)
