Ben Witherington has finally completed his book trilogy on the sacraments of the Protestant church. I have yet to read them, but I certainly hope to one day. Until then, from what I have heard, these books are highly recommended and very helpful for anyone looking to develop their sacramental theology and to be challenged to think outside your own understanding of the Sacraments of Baptism, the Lord’s Supper, and the Word.
Here is the trilogy:
Troubled Waters: Rethinking the Theology of Baptism
Making a Meal of It: Rethinking the Theology of the Lord’s Supper
The Living Word of God: Rethinking the Theology of the Bible
