In every generation, the church is commanded to "contend for the faith once for all delivered to the saints." That is no easy task, and it is complicated by the multiple attacks upon Christian truth that mark our contemporary age. Assaults upon the Christian faith are no longer directed only at isolated doctrines. The entire structure of Christian truth is now under attack by those who would subvert Christianity's theological integrity.

Today's Christian faces the daunting task of strategizing which Christian doctrines and theological issues are to be given highest priority in terms of our contemporary context. This applies both to the public defense of Christianity in face of the secular challenge and the internal responsibility of dealing with doctrinal disagreements. Neither is an easy task, but theological seriousness and maturity demand that we consider doctrinal issues in terms of their relative importance. God's truth is to be defended at every point and in every detail, but responsible Christians must determine which issues deserve first-rank attention in a time of theological crisis.

A trip to the local hospital Emergency Room some years ago alerted me to an intellectual tool that is most helpful in fulfilling our theological responsibility. In recent years, emergency medical personnel have practiced a discipline known as triage--a process that allows trained personnel to make a quick evaluation of relative medical urgency. Given the chaos of an Emergency Room reception area, someone must be armed with the medical expertise to make an immediate determination of medical priority. Which patients should be rushed into surgery? Which patients can wait for a less urgent examination? Medical personnel cannot flinch from asking these questions, and from taking responsibility to give the patients with the most critical needs top priority in terms of treatment.

The word triage comes from the French word trier, which means "to sort." Thus, the triage officer in the medical context is the front-line agent for deciding which patients need the most urgent treatment. Without such a process, the scraped knee would receive the same urgency of consideration as a gunshot wound to the chest. The same discipline that brings order to the hectic arena of the Emergency Room can also offer great assistance to Christians defending truth in the present age.

A discipline of theological triage would require Christians to determine a scale of theological urgency that would correspond to the medical world's framework for medical priority. With this in mind, I would suggest three different levels of theological urgency, each corresponding to a set of issues and theological priorities found in current doctrinal debates.

First-level theological issues would include those doctrines most central and essential to the Christian faith. Included among these most crucial doctrines would be doctrines such as the Trinity, the full deity and humanity of Jesus Christ, justification by faith, and the authority of Scripture.

In the earliest centuries of the Christian movement, heretics directed their most dangerous attacks upon the church's understanding of who Jesus is, and in what sense He is the very Son of God. Other crucial debates concerned the question of how the Son is related to the Father and the Holy Spirit. The earliest creeds and councils of the church were, in essence, emergency measures taken to protect the central core of Christian doctrine. At historic turning-points such as the councils at Nicaea, Constantinople, and Chalcedon, orthodoxy was vindicated and heresy was condemned--and these councils dealt with doctrines of unquestionable first-order importance. Christianity stands or falls on the affirmation that Jesus Christ is fully man and fully God.

The church quickly moved to affirm that the full deity and full humanity of Jesus Christ are absolutely necessary to the Christian faith. Any denial of what has become known as Nicaean-Chalcedonian Christology is, by definition, condemned as a heresy. The essential truths of the incarnation include the death, burial, and bodily resurrection of the Lord Jesus Christ. Those who deny these revealed truths are, by definition, not Christians.
