What if the church, in years gone by, would have opted for an agnostic approach (we really can't know) or an attitude of the pacifist (we just need unity)? Where would we be today on matters of Christ's deity, the Trinity, the atonement, justification by grace alone through faith alone, "free-will" and fifty other controversies? The answer's simple. There would be no church as we know it today.
Christianity is marked by a confession—we hold certain assertions or doctrines to be true. You get rid of these—the simple and the complex—and you have nothing left. You might as well go home because you’ve been robbed of all your wealth. Churches today that have a large umbrella and are willing to take in any faith or those churches that minimize the relevance of specific truth and only promote therapeutic themes are all bankrupt. They stand for nothing and have nothing of any benefit to offer.
So what should be done about the controversies? Whether we want to acknowledge it or not, truth is still recognizable and there are many who want to pervert the purity of Scripture to attain their own ends. In a spirit of humility, love and concern for her Lord the truth and the church, we must continue to wrestle through difficult discussions and heresies. (Isn't "heresies" a strange word. We rarely use it any more today.) As Jude wrote: Beloved, although I was very eager to write to you about our common salvation, I found it necessary to write appealing to you to contend for the faith that was once for all delivered to the saints. For certain people have crept in unnoticed who long ago were designated for this condemnation, ungodly people, who pervert the grace of our God into sensuality and deny our only Master and Lord, Jesus Christ. (Jude 1:3-4 ESV) Isn't it amazing that the apostle says, "I'd really like to write about the glorious gospel, but I'm compelled to urge you to fight for the core doctrines of the faith." And we must do the same.
We stand in jeopardy of snoozing through some serious apostasies right now, and our apathy and lack of discernment rank right up there with the lowest points in church history. Let's wake up and get smart on the controversies of the day realizing that so much is at stake. Let's not go looking for a fight (that's not a healthy approach), but when necessary let's fight for the truth that has gripped our souls.
