Everything in the Christian life is doctrine. Very often Christians equate “doctrine” with “theology.” That makes sense. We have the doctrine of God, doctrine of man, doctrine of Scripture, and so forth. Those are the Bible’s teachings on certain topics. Those doctrines are what we call theology.
But the word “doctrine” is simply the word “teaching.” Therefore, the Bible teaches us what to believe and how to live. The Bible teaches us theology and ethics. The Bible teaches us that God is a Trinity, and that we must worship Him. The Bible teaches us that man is sinful, and that we must confront sinners if we are to call ourselves Christians. The Bible teaches us that the church is God’s “called out” community, and that the church must love one another.
There is no dichotomy between doctrine and ethics, right theology and right living. The Bible teaches us what to believe is right theology, and what to believe is right living (i.e., “I believe God is one, and I believe a man should be faithful to his wife”). It is no wonder Paul would tell Timothy that the Law is meant to confront all who break the law– “lawless and disobedient…ungodly…murderers…sexually immoral…liars…and whatever else is contrary to sound doctrine” (1 Tim 1.8-11). Everything in the Christian life is doctrine. God has taught us what to believe about everything that has to do with pleasing Him.
This is why our church has a Statement of Faith (theology) and Church Covenant (ethics). It is the only way we know how to uphold Christian doctrine.
