Two Testaments, One Problem: Reclaiming Christianity for the Age of Love

by Dominic Knight

Discover the Freedom of the Fulfilled Covenant

For centuries, many Christians have been told that the Old and New Testaments must be perfectly harmonized — that the laws, purity codes, and ceremonial practices of ancient Israel still carry weight for followers of Christ today. This belief has led to confusion, strained interpretations, and a faith often burdened by obligations never meant for the New Covenant.

In this clear and thought-provoking work, Dominic Knight traces a deeply personal

From a devout Catholic upbringing,

Through disenchantment when key doctrines proved absent from Scripture,

Into years of searching without a church,

Conversion to Lutheranism,

And finally, a rediscovery of the liberating truth — that Jesus fully and finally fulfilled the Old Covenant.

Drawing on careful reading of Scripture, accessible theological insight, and lived experience, this book dismantles the need to “force-fit” Old Testament narratives into the teachings of Christ. Instead, it reveals the Gospel as a complete, sufficient covenant that frees believers from the weight of outdated law.

You’ll

Why the Old Covenant cannot be blended with the New without distortion

How the early Church navigated the tension between law and grace

Why Jesus’ fulfillment of the law is more than a doctrinal point — it’s a life-changing reality

How to approach Scripture without fear of contradiction

Written for Christians of all backgrounds — from lifelong churchgoers to those disillusioned by institutional religion — this book is both a theological exploration and an invitation to renewed spiritual clarity.

If you’ve ever felt uneasy about strained explanations or wondered why some teachings seem forced, this book offers a path toward peace — and the courage to let the old truly pass away.

For readers of Bart D. Ehrman, N. T. Wright, and Philip Yancey — and for every believer who suspects the Gospel is simpler, and freer, than they’ve been told.

About the author

Dominic Knight was one of the founders of The Chaser satirical newspaper in 1999, and also one of its destroyers in 2004 after the group finally acknowledged that it would never turn a profit. Since then he’s worked on the team’s various projects in print, stage, radio, television and online. Most recently he wrote for ABC-TV’sThe Hamster Wheel, Yes We Canberra! and The Chaser’s War On Everything.
In recent years, Dominic has begun writing fiction in an attempt to spend less time with his Chaser compatriots. His first novel Disco Boy (2009) portrayed the career travails of a disaffected law graduate suspiciously like himself, and its successor Comrades (2010) delved into the grubby world of student politics. He’s working on a third novel, which may appear in 2013 in the unlikely event that he gets his act together. Dominic regularly appears at various writers’ festivals whether he’s invited to speak or not, and is currently on the board of the National Young Writers’ Festival.

In 2012, Dominic began hosting Evenings on ABC Local Radio in NSW and the ACT. He can be heard from 7-10pm Monday to Friday on 702 ABC Sydney, 666 ABC Canberra, 1233 ABC Newcastle and ABC stations across NSW.

Dominic has lived in Sydney nearly all of his life and plays the bass reasonably well and tennis appallingly. He is overly fond of karaoke.
