Has the Church made too much of the Trinity? Reading Life in the Trinity by Donald Fairbairn makes me realize that this doctrine is crucial and practical.

What is the heart of Christian life? Fairbairn suggests “part of the answer is that a life reflecting the love Jesus has shown for us lies close to the heart.” He sees “first and foremost, then, Christian life is a process of abiding in Christ, of relying on him, of recognizing and maintaining one’s connection to him in all aspects of life.”

To take it further, and where the real beauty of this book lies, is seeing our relationship with Christ in terms of his relationship with the Father and the Holy Spirit. Fairbairn writes, “He (Christ) is offering himself to us as a person, that we might share in his most deeply personal relationship, the relationship he has with God the Father.” Seen in this context, the Christian life is a sharing in the life of the Trinity. This is the scarlet thread that runs through every chapter.

Fairbairn expertly walks readers through Trinitarian theology, which is fascinating, but his most important work is sharing relational and practical implications. He makes it clear that the worth of everyone lies in our being made in the image of God. “Christianity teaches us that our significance does not ultimately lie in what we accomplish or what we do: it lies in the one to whom we belong,” he writes. “Our significance is not something that can be earned; it is something given to us by God.”

He is also a wise guide into the thought of the Church fathers. He makes judicious use of their writings, to inform modern perspectives that can be lacking. He draws most from four Patristic writers: Irenaeus of Lyons, Athanasius of Alexandria, Augustine of Hippo and Cyril of Alexandria. Readers get some of their most fruitful and biblical thoughts.

The only time I felt unsure of Fairbairn was his discussion of John 6 where Jesus enjoins eating his flesh and drinking his blood. Fairbairn sees this as a reference to celebrating the Eucharist. He notes that “the early church saw its regular celebration of the Eucharist as crucial to believers’ continuation in Christian life.” He adds, “To say that the Eucharist is central is to imply that communal worship in general is central to the cultivation of people’s relationship to the Father and the Son.” He closes this section by observing that “in the mind of the early church, cultivating a direct relationship to Christ was not by any means an individual task. It involved the entire community of faith, as well as the devotion of each individual…. Life in the Trinity is life in the church and involves regular participation in the worship and the mysteries Christ has entrusted to the church.”

This is not intended to be a comprehensive book in theology but rather a supplement to the more exhaustive and systematic variety.

Just catching the glimpse this book gives of the Trinity is staggering. It is also mind-boggling to realize that becoming a Christian makes us part of this triune fellowship. Being able to better see the Godhead and the beautiful relationship it engenders, makes this a lovely book.
