What do we know about the church in Sardis?

WHAT DOES THE BIBLE SAY?

It is unknown who started the church in Sardis, and there is little historical record of what became of it. Therefore, what we know is mostly from Revelation 3:1–6, Jesus’ letter to this church. That letter, among the letters distributed to seven churches, is one of the harsher. It opens by saying they have the appearance of spiritual life but are actually dead (Revelation 3:1b). As a church, it was spiritually on its last breath (Revelation 3:2a) and needed to “wake up.” The language Jesus employs about waking up echoes the city of Sardis’ own weakness and was likely an intentional allusion. The city was twice ransacked, by Cyrus the Great in 546 BC and by Antiochus III in 218 BC, because its watchmen grew lazy. Jesus likewise told the church to “wake up” lest He come against them like a thief (Revelation 3:3c). While their exact error is unknown, it appears that the church was busy acting like a church, but Jesus knew their heart.

At the same time, Jesus commended those in Sardis who remained faithful and pure (Revelation 3:4). For those individuals, Jesus encouraged them to persevere, promising eternal life and Jesus’ commendation to the Father (Revelation 3:5). The church in Sardis serves as a sobering warning that Christianity can look alive outwardly while dying inwardly. Church is meant to be a place where believers spiritually grow and mature—not where faith quietly falls asleep beneath empty routine and religious appearance.

FROM THE OLD TESTAMENT

• The church in Sardis is not mentioned in the Old Testament.

FROM THE NEW TESTAMENT

• In Revelation 2–3, seven letters by Jesus are written to seven churches. Of those seven, the one to the church of Sardis is the most harsh (Revelation 3:1–6). Unlike others that open with something good to say before offering a corrective, this one opens with a rebuke: “I know your works. You have the reputation of being alive, but you are dead” (Revelation 3:1).
• From the limited information we have, it appears that this church still looked like a church but was almost spiritually dead. Jesus urges, “Wake up, and strengthen what remains and is about to die, for I have not found your works complete in the sight of my God” (Revelation 3:2). The language of waking up is that of a final warning. They are “about to die,” and will do so if they do not heed this warning. We do not know exactly what they were doing wrong, but this is a sober warning about how a church can physically exist yet be rejected by Jesus.
• Jesus was likely alluding to Sardis' history of conquest due to the watchmen's laziness, first by Cyrus the Great in 546 BC and again by Antiochus III in 218 BC. Jesus was telling the church to spiritually “wake up” or else “I will come like a thief, and you will not know at what hour I will come against you” (Revelation 3:3c). Jesus would overthrow the church if they did not repent and turn back to Him (Revelation 3:3b).
• Why had Jesus not yet removed them as a church? While most of the church was dead, “Yet you have still a few names in Sardis, people who have not soiled their garments, and they will walk with me in white, for they are worthy” (Revelation 3:4). There were still some faithful followers of Christ in this dying church. It seems that Jesus allowed the church of Sardis to linger for their sake.
• Speaking to those faithful, Jesus encouraged them to “conquer,” a word meaning “persevere.” The reward for doing so was significant: “The one who conquers will be clothed thus in white garments, and I will never blot his name out of the book of life. I will confess his name before my Father and before his angels” (Revelation 3:5). Unlike the rest of the church that Jesus was commanding to wake up or be lost, Jesus was encouraging these individuals to continue as they were, reminding them of God’s hope for His faithful.
• This article does not have time to explain Jesus’ difficult statement fully: “I will never blot his name out of the book of life.” Jesus, however, is not speaking about a works-based salvation (personal perseverance leads to salvation or keeps it), but about perseverance as assurance that one is and will be saved. Thus, “the one who conquers” is the one who is in Jesus, who has conquered on their behalf.

IMPLICATIONS FOR TODAY

The church of Sardis only looked like a church. They were doing “churchy things,” but that activity was merely external, not in love or service to Him. This should be a wake-up call! If we aren't being careful, we might find out that we've been playing church our entire lives. Being a Christian isn't about doing certain spiritual activities. It's about having a relationship with God through His Son, Jesus. Just like our spouses and parents would not be happy if we just did the bare minimum to fulfill our duties as husband, wife, or child, God is not pleased when we treat Christianity as a series of necessary activities to fit into our lives. That's not an expression of love!

While we don't know how the church of Sardis ended up, history is filled with churches that ceased being alive. One such cause has been when formality of worship overtook love of God and others.

We can guard against this in our own churches by checking the motivations of our hearts for everything we do. It’s OK to have structure in church, but we need to ask whether the order of our service is intended to facilitate joyful worship for God. If we answer that we do what we do at church “just because,” then we need to stop and think carefully about Jesus’ warning to the church in Sardis. Our church services should be purposeful times where we worship God, hear Scripture preached, take communion, fellowship with other believers, and so forth. In short, the church is where our spiritual life is cultivated and grown. When it falls asleep, first the church, then its believers, start to die!

UNDERSTAND

• The church in Sardis received one of the harshest assessments of the seven churches because it was spiritually dead despite maintaining the outward appearance of a living congregation.
• Jesus called the church at Sardis to "wake up" out of complacency.
• A small faithful remnant within the dying church of Sardis was commended, however, and a reminder for us to remain faithful too.

REFLECT

• How does the warning to the church in Sardis challenge you to examine whether you are spiritually alive or dead?
• In what ways might you personally be going through the motions of Christian life (attending, serving, appearing faithful) without genuine spiritual life beneath the surface?
• How does the example of the faithful remnant in Sardis inform the way you think about your own responsibility to remain faithful?

ENGAGE

• What does Jesus' declaration that a church can be outwardly alive yet spiritually dead reveal about the inadequacy of using attendance, activity, or reputation as the primary measures of a church's health?
• In what ways can a church or individual believer appear active and faithful on the outside while slowly drifting into spiritual complacency on the inside?
• How can we heed the warning to Sardis to wake up and live a vibrant, faithful life of faith?
