How to Talk About Faith With Muslim Colleagues Without Making It Weird

Andy Bannister spent six years working in the NHS as what he cheerfully calls an "undercover Christian." Church life on one side, the office on the other, and never the twain shall meet. He now runs Solas, an evangelism and training organisation, and has spent decades talking with Muslims, from ladder-top debates at Speakers' Corner to a PhD on the Quran. In a conversation with Transform Work's Gabby Connell, he lays out what he wishes he had known on day one. Here is the short version.

Start by not hiding

Bannister's first point is that the hardest part isn't the conversation itself but the silence beforehand. If your colleagues never learn that faith matters to you, there is nothing to build on. His fix is wonderfully low-key: when someone asks about your weekend on Monday morning, don't skip the church bit. Mention the football, the barbecue, and the sermon in the same breath. When you join a new team and introduce yourself, put your faith in the list alongside the rock climbing and the kids. You haven't made a speech, but you have planted a flag, and your Muslim colleagues will notice it as much as anyone.

His second point is that you shouldn't do any of this alone. After every afternoon at Speakers' Corner, his team went to KFC to swap stories, pray, and pick each other up. A workplace version works just as well: find even one other Christian, pray for each other, and debrief when things go well or badly.

Be curious before you are clever

When it comes to the conversation itself, Bannister recommends the humblest possible opening. Something like, "Forgive me for asking, but I think you're a Muslim, am I right? I'm a Christian and I don't really know much about what you believe. What do you folks believe?" Then listen. Don't push back or correct. Just ask follow-up questions and clarify.

After five or six minutes, he suggests a gentle turn: some of what you've described we share, but there are a few differences that intrigue me. Most of the time your colleague will say, "Such as?" and the door is open. If they don't, you can supply the "such as" yourself. The order matters. Because you listened first, you've earned a hearing .

Feed people

If there is one practical tip to take away, it is this one: hospitality beats cubicle chats. Buy a colleague a sandwich. Invite them for lunch. If you're friends, invite them home. Bannister tells the story of a friend who knew a Muslim colleague for eight years before inviting him to dinner. At the door that night, the colleague said it was his first time inside a Christian home in 25 years in the UK. Faith came up quickly, and many more conversations followed. The only barrier had been the invitation .

Know where the landmines are

Two topics deserve caution. The first is Middle East politics, where feelings run high on every side. If your colleague raises it, Bannister suggests saying you care about justice, can see injustice on both sides, don't know enough to comment, and are praying for peace. That is honest and it lets you step aside gracefully.

The second is Muhammad. You can acknowledge that he matters enormously to your friend without agreeing with his claims, but mockery or rudeness is a quick way to end a friendship. Bannister's broader principle is that people are equal, but ideas aren't. You can respect someone deeply and still disagree with what they believe, and being honest about the differences is not disrespectful.

If you do need to say something sensitive, it helps to frame it. He once told a Muslim taxi driver, in effect, that he didn't want to upset him but that his conclusions after seven years of research on the Quran differed from the driver's. The driver, curious, asked to hear them, listened carefully, and admitted that Muslims aren't always good at asking tough questions of their own tradition.

The "same God" question

Many people assume Christians and Muslims worship the same God with different names. Bannister, who wrote a book on this, argues that this is an assumption worth examining. His case, in brief, is that the Bible presents a God who is relational, who can be known, who is love, and who suffers in Christ, while the Quran, in his reading, doesn't present God in those terms and has no category of salvation in the Christian sense. These are his arguments and Muslims would of course answer them differently.

What's useful is how he suggests raising it: not as a debating point, but as a question. Ask your friend, "What is God like to you?" If they mention love, you could read Romans 5:8 together and ask whether there is something similar in their scripture. You're inviting comparison rather than starting a fight.

You don't need all the answers

A fear that holds many people back is being asked something they can't answer. Bannister's advice, printed on the cover of his book, is Don't Panic. Say it's a great question, admit you don't know, and promise to find out. Then do. Come back a few days later with an answer and you will have shown more care than any instant reply could. You also don't need to read the Quran. An accessible introduction, such as Nick Chatrath's Reaching Muslims, is plenty unless many of your colleagues are Muslim and you feel called to go deeper.

When it gets heated or you feel flat

If a conversation gets tense, name it and apologise if needed, as in, "I can see you're passionate and so am I, but I want to stay friends, so let's leave it for today." Better still, pull the conversation back to something warmer. Suggest that each of you brings a favourite verse, one from the Quran and one from the Bible, and explains why it matters. Bannister says these exchanges almost always end up focusing on the Bible, and they work especially well with the stories of Jesus.

And if you simply feel spiritually flat, he says not to beat yourself up. Talk to someone, pray honestly, and keep being a kind and curious colleague. Then if an opportunity opens up, the groundwork is already there.

Don't fear losing the friendship

Bannister says he has never seen a considerate conversation wreck a relationship. People are more likely to fear causing offence than to cause it. He adds that many Muslims actually read Christian hesitancy as a sign that we don't really believe anything, so quiet confidence is respected.

He also asks for patience. One of his friends spent five years in conversation with a committed Muslim colleague before that colleague became a Christian. Most journeys involve many people and many conversations, so your job isn't to carry someone's salvation on your shoulders. It is to be a faithful, friendly witness and let God do the rest.

Where to start this week

Pray for a couple of colleagues by name, and put their names somewhere you'll see them. Mention your church in your next Monday catch-up. Ask one Muslim colleague to lunch and let your curiosity do the talking. And, a small practical note: it's worth checking your employer's policy on discussing religion, and keeping the conversation invited and two-way rather than pushed.

Taken together, the message is that most of this is simply being a good friend, with a little courage on top.
