Puritan pastor Richard Baxter took an old Latin phrase and popularized it in his day, in English. It is simple, but profound: “In essentials, unity; in non-essentials, liberty; in all things, charity.” Why was Baxter so concerned to see Christians publicly, charitably, doctrinally unified? Baxter, writing in 17th century England about the evil effects of division in the church, made this observation:
Exhort one another every day, as long as it is called “today,” that none of you may be hardened by the deceitfulness of sin (Hebrews 3:13). I was thinking this past week about cases where a person who has been a professed believer, maybe even a well-known Christian leader, falls into public sin or even apostasy, walking away from the Christian faith. Sadly, there have been many such cases in the news lately.
Imagine you are about to move to a new area. Not just a new location, but a whole new part of the world—surrounded by a new culture and new faces, and without any familiar friends or contacts. Besides the personal, emotional challenges of such a move there would obviously be some significant spiritual challenges to anticipate. Whatever spiritual habits you have in place will be changed or challenged; the fellow Christians by whom you’ve been encouraged and to whom you’ve been accountable won’t be nearby to help you.
For in one Spirit we were all baptized into one body—Jews or Greeks, slaves or free—and all were made to drink of one Spirit (1 Corinthians 12:13). In the middle of this famous chapter on spiritual gifts, Paul makes it clear that partaking of the Spirit of God is something that every Christian experiences. The physical baptism we experience in the church is a symbol of the spiritual baptism of every believer by the Spirit!
What does the church of Jesus Christ really look like? Of course, I am not talking about the architectural style of the building in which it meets, but what a local body of believers looks like. We know the church should be sound in doctrine and zealous in proclaiming the gospel. But how does a sound church really function?
