In Fountain of Salvation, Fred Sanders offers a wonderful introduction to the Trinity as the object of Christian worship and as a belief inseparable from and indeed structuring the doctrine of salvation. He then leads us clearly, interestingly, and dependably through recent theological debates on this fundamental Christian belief, always showing us where (and where not) those debates really do enable Christians to grow in knowledge of the Triune life. Across Christian traditions Sanders’s argument should resonate and inspire.
