There are appointments you do not miss. You do not “get around to” a court appointment. If you’ve been summoned, you do not elect to stay home because you stayed up too late the night before or because something else suddenly came up that you decided would be more enjoyable.

You go. You show up.

The same is true for so many other things in life. I don’t have cancer. But if I did, I couldn’t imagine just not showing up to my scheduled treatments. I mean, are there any cancer patients out there reading this who’d honestly skip a cancer treatment because it was maybe scheduled too early in the morning, or because it was further away than you’d prefer to drive, or because you felt like doing something else instead, like maybe fishing or gardening or whatever? Of all the people in the world, I’m sure cancer patients epitomize exhaustion, especially during treatment. And yet, none would shrug and say, “Something else came up,” or “I’m just too tired,” as though what they were facing, and the appointments in place to deal with it, were no big deal.

We show up when something is important to us—when we believe we need to be there.

You know where I’m going with this, don’t you?

Before I do, let me first say to those who’d say outright they don’t need to be in church because they can be “spiritual” without it, feel free to sit this one out. I’m not really talking to you. You’ve already made clear you will not allow the Bible to serve as an external authority to govern you. You already live by a standard of picking and choosing based on preference. And so, you’ll do “spiritual” things when you prefer, maybe when it fits your inner sense of meaning, and you won’t when it doesn’t. By the way, I don’t mean to commend you, but I suppose I’m willing to applaud your consistency at least. You are reliable in that sense.

I should make another quick clarification. For example, we just offered an Epiphany service here at Our Savior on Tuesday, January 6. Forty people attended. That’s only about 15% of what’s typical of our regularly scheduled Sunday morning service attendance. I’m not writing to the faithful Christians in our midst who could not attend our Epiphany service. I say this because even Luther acknowledged in his explanation of the Third Commandment in the Large Catechism that “there should be worship daily; however, since this is more than the common people can do, at least one day in the week must be set apart for it.” In other words, I’m not speaking to those who simply cannot attend the special services for life’s various reasons.

But what I am writing here is addressed to those who deliberately stake a public claim in Christianity and yet see no reason to attend worship with any regularity.

In short, if you confess that Christ is Lord, then I’m assuming you believe His Word. I’m also assuming you realize that the Bible explicitly commands faithfulness in worship (Hebrews 10:24-25, Acts 2:42, and 1 Corinthians 14:26). What’s more, it is thoroughly assumed throughout the rest of the scriptures. There’s no question it was an Old Testament pattern. God expected His people to assemble (Leviticus 23:3, Deuteronomy 16:16, Psalm 122:1, Psalm 84:10, Nehemiah 8:1–3, 16, and others). And for the record, Jesus maintained the pattern (Luke 4:16, Matthew 18:20; I suppose it can be assumed also in Matthew 5:23-24 and John 4:23-24). It was also maintained by the newly emerging Church (Acts 20:7, Acts 13:44, and others).

Beyond even these things, if a reader is being honest, Saint Paul more than betrays the standard of regularly scheduled worship in 1 Corinthians 11:18 when he writes “when you come together as a church” (συνερχομένων ὑμῶν ἐν ἐκκλησίᾳ). First of all, not if but when. Next, the first word in that phrase—συνερχομένων —has in its root the sense of traveling to a place to be together. Where is this traveling bunch going? The destination is ἐκκλησίᾳ—church. But couldn’t this just mean that when they are traveling together to Cedar Point in Ohio, even then, they are the Church, that is, the body of Christ in the formal sense? Of course. All believers in Christ, at all times and in all places, comprise the Church. But that’s not the point here. Paul is already talking about things that happen in worship, namely, the administration of the Lord’s Supper. In this context, Paul is casually indicating that normal Christians (so long as they are not physically incapable because they are sick, elderly, in prison, or something of that sort) travel to a place to occupy it—to be in it. The preposition ἐν does not mean “as.” It means “in.” In other words, “as” the Church, they travel to be together “in” a church.

Add to this the other reasons why Paul would encourage the Church to gather. Mutual edification is one that seems rather important to him (Ephesians 4:15-16, Colossians 3:16, Romans 12:4-5, and others). But even beyond this, God’s Word does not hide the warning of what can happen when we drift from faithful attendance in worship. Our hearts are more easily hardened (Hebrews 3:12-13), spiritual decline occurs (Judges 21:25), and we become more vulnerable to sin and Satan’s snares (Ecclesiastes 4:9-12).

For the Lutherans reading my words, consider your creedal and confessional heritage. Again, Luther reminds us in his explanation of the Third Commandment in the Large Catechism that “God insists upon a strict observance of [regular Sabbath worship] and will punish all who despise his Word and refuse to hear and learn it, especially at the times appointed.”

For those less familiar with Luther and more inclined toward others in mainstream evangelicalism, consider Billy Graham, who said so very plainly that “if you are a Christian, you should go to church.” And why? He continued that a Christian “has no right to neglect the church. It is God’s plan for the nurture and strengthening of His people.” And in another place, Graham wrote, “The church is the place where believers are fed, encouraged, and strengthened to face the world.”

Now, if Billy Graham isn’t enough for you, consider others from across the Christian spectrum—folks like John MacArthur, who said, “If a [church member] shows prolonged negligence in gathering with God’s people… how can he say he loves God?” Or maybe even someone like Dwight Moody, who insisted that “Church attendance is as vital to a disciple as a transfusion of rich, healthy blood to a sick man.” Or Paul Washer, who preached, “A believer who refuses the local church is a contradiction.” Or John Piper, who maintained, “The corporate gathering of believers is the single most important event in the life of the Church.”

Apart from Luther, I’m not in strict theological unity with any of the above preachers I just mentioned. And yet, it sure seems that faithfulness in worship is one thing that has not slipped through any of our theological divides. That’s because it’s a pretty straightforward standard that can only be set aside deliberately.

In the end, it’s really not that complicated. If Christ is real, and He is truly preeminent in your life, then none of the above proofs could ever be suggestions. Instead, they are divine appointments. Sure, we may not feel like keeping the appointments. Still, we know they’re important—and they’re good for us—and so, we show up. And so, our deliberate disregard or neglect of these things could never be interpreted as neutral behavior. Instead, it reveals something else altogether, and it does so rather crisply. Compared to the other practical examples I shared, it shows that, functionally, Christ is less significant to you. It reveals that forgiveness of sins, life, and salvation are nice, but not as nice as, perhaps, one’s bed after a long Saturday night of this and that with friends.

As a pastor, the saddest part here is that deliberate disregard for worship is a public demonstration of unbelief. Maybe not necessarily unbelief in the sense of open denial, but, at a minimum, it is unbelief expressed in practice. Both are public. The first is at least honest. The second is simply hypocritical. It is an observable contradiction, sort of like Washer pointed out. By staking a claim in Christianity, one assumes devotion to God and His body, the Church. And yet, there is no desire to show up as part of that body. So, what gives?

Well, belief orders life. What we choose and what we neglect reveal what we do and do not truly believe or consider valuable. To absent oneself so carelessly can be nothing less than to declare that God means very little to you by comparison to all the other appointments in life you’d never in a million years consider blowing off.

Again, no one would say, “I believe my cancer treatments are crucial, but I’ll only go when it feels convenient.” No one would ever say, “Your honor, I respect you and all, but I have some friends coming over this morning that I haven’t seen in a long time, so I’ll have to catch up on this court case a different time.” No one would ever call a beloved daughter right before her wedding and say, “I know it’s important for me to be there, but I haven’t been to my cabin up north in a while, so I’m not going to be able to make it.”

Do these things, and see what happens. Actually, I can just tell you what will happen. There will be trouble.
