"Mere Christianity" Christians

Chaplain Mike at Internet Monk asked his readers to discuss whether "'Mere Christianity Christians,' i.e. Christians who emphasize the smaller, more minimal and broadly efficient vision of C.S. Lewis and some of the early church fathers personified in the Apostles’ Creed" are a threat to Evangelicalism. One of the commenters provided this from Lewis's Mere Christianity:

I hope no reader will suppose that ‘mere’ Christianity is here put forward as an alternative to the creeds of the existing communions—as if a man could adopt it in preference to Congregationalism or Greek Orthodoxy or anything else. It is more like a hall out of which doors open into several rooms. If I can bring anyone into that hall I shall have done what I attempted. But it is in the rooms, not in the hall, that there are fires and chairs and meals. The hall is a place to wait in, a place from which to try the various doors, not a place to live in. For that purpose the worst of the rooms (whichever that may be) is, I think, preferable.

It is true that some people may find they have to wait in the hall for a considerable time, while others feel certain almost at once which door they must knock at. I do not know why there is this difference, but I am sure God keeps no one waiting unless He sees that it is good for him to wait. When you do get into your room you will find that the long wait has done you some kind of good which you would not have had otherwise. But you must regard it as waiting, not as camping. You must keep on praying for light: and, of course, even in the hall, you must begin trying to obey the rules which are common to the whole house. And above all you must be asking which door is the true one; not which pleases you best by its paint and paneling.

Conversion brings the new believer into the hallway — "mere" Christianity" — orthodoxy — and what he concludes about other doctrines determines which denominational door he enters. Lewis was critical of those who insist on excluding as non-Christians those who choose one door off the hallway rather than another. That is not to say that there are not very important differences between rooms, but they are not differences that put the occupants outside the house of faith.

I was reminded of Albert Mohler's notion of "theological triage":

.... 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. ....

.... The set of second-order doctrines is distinguished from the first-order set by the fact that believing Christians may disagree on the second-order issues, though this disagreement will create significant boundaries between believers. When Christians organize themselves into congregations and denominational forms, these boundaries become evident.

Second-order issues would include the meaning and mode of baptism. Baptists and Presbyterians, for example, fervently disagree over the most basic understanding of Christian baptism. The practice of infant baptism is inconceivable to the Baptist mind, while Presbyterians trace infant baptism to their most basic understanding of the covenant. Standing together on the first-order doctrines, Baptists and Presbyterians eagerly recognize each other as believing Christians, but recognize that disagreement on issues of this importance will prevent fellowship within the same congregation or denomination. ....

Third-order issues are doctrines over which Christians may disagree and remain in close fellowship, even within local congregations. I would put most of the debates over eschatology, for example, in this category. Christians who affirm the bodily, historical, and victorious return of the Lord Jesus Christ may differ over timetable and sequence without rupturing the fellowship of the church. Christians may find themselves in disagreement over any number of issues related to the interpretation of difficult texts or the understanding of matters of common disagreement. Nevertheless, standing together on issues of more urgent importance, believers are able to accept one another without compromise when third-order issues are in question. .... (more)

My denominational affiliation is clearly the result of "second-order" doctrines including baptism and the Sabbath. The most destructive arguments among Christians, it seems to me, result from insisting that secondary and tertiary issues be considered essential.
