Admittedly I haven’t worked my way through all of this, but from what I’ve seen it’s a strong contender for the best modern Systematic Theology. Letham says that his ‘main innovation’ is attempting to integrate soteriology and ecclesiology – though that in itself flows from his commitment to the Westminster Confession of Faith’s teaching that outside the church ‘there is no ordinary possibility of salvation’. The book is very readable, broken up into nice short sections, and with study questions and a bibliography at the end of each chapter. He deals with some very current debates such as two kingdoms theology (which he amusingly describes as ‘reformed dispensationalism’) and paedocommunion. As Carl Trueman has written, ‘here we have the full fruits of a lifetime of thinking theologically’.
