Doctrine is, quite literally, the teaching of the church - what the church understands to be the substance of its faith. It is no substitute for personal experience. Evangelical Christians have given clear witness to the necessity of personal faith in Jesus Christ, but that personal faith is based in some specific understanding of who Jesus Christ is and what He accomplished on the cross. After all, we do not call persons to profess faith in faith, but faith in Christ.
There is no Christianity "in general." Faith in some experience devoid of theological or biblical content - no matter how powerful - is not New Testament Christianity. Those called to Christianity in general may believe nothing in particular. But faith resides in particulars.
Some churches seem to think that doctrine is a concern for those of a certain intellectual bent, but unnecessary for most Christians. Interest in doctrine amounts to something like an intellectual hobby. Others steer clear of doctrine for fear of argument or division in the church. Both factors indicate a lack of respect for the Christian believer and an abdication of the teaching function of the church.
Those who sow disdain and disinterest in biblical doctrine will reap a harvest of rootless and fruitless Christians. Doctrine is not a challenge to experiential religion; it testifies to the content of that experience. The church is charged to call persons to Christ and to root them in a mature knowledge of Christian faith.
