The highest science, the loftiest speculation, the mightiest philosophy, which can engage the attention of a child of God is the name, the nature, the person, the doings, and the existence of the great God which he calls his Father.
— Charles Spurgeon, quoted in The Truth Project by Del Tackett, Lesson 3 at 16:04
The dividing line between “the faith” of Christianity and faiths which are not Christian is a line built of doctrines—doctrines which are essential to the faith.
— Calvin Beisner, from God in Three Persons, p. 11
Machen writes, “But if any one fact is clear, on the basis of this evidence, it is that the Christian movement at its inception was not just a way of life in the modern sense, but a way of life founded upon a message. It was based, not upon mere feeling, not upon a mere program of work, but upon an account of facts. In other words it was based upon doctrine.” As soon as you say Jesus died and rose again for your sins according to the Scriptures, you have doctrine. You have a message about what happened in history and what it means. That’s theology. There is no gospel without it.
— Kevin DeYoung, from Why We’re Not Emergent, p. 113
Theology is for everyone. Indeed, everyone needs to be a theologian. In reality, everyone is a theologian—of one sort or another. And therein lies the problem. There is nothing wrong with being an amateur theologian or a professional theologian, but there is everything wrong with being an ignorant or sloppy theologian.

What is it that we Christians affirm when we sing and recite and pray to the true and living God who is Father, Son, and Holy Spirit? One God, yet a Godhead of three; three Persons, yet one God—how did we arrive at this understanding? Is it truly the teaching of Scripture, and must we believe this same truth today? Why did the church insist so early that we hold this doctrine of God? Does it have any impact upon our larger theological understanding? Further, does it matter in terms of our own lives of faith and worship and prayer?

No Christian can avoid theology. Every Christian has a theology. The issue, then, is not, do we want to have a theology? That’s a given. The real issue is, do we have a sound theology? Do we embrace true or false doctrine?
