Churches and branding sound like two words which shouldn’t go in the same sentence. While of course Jesus never had a marketing campaign, the church in general has a problem of being clear what they are about.
A church logo is at the heart of what you communicate, and from which the rest of the branding flows. For example, a green circular logo wouldn’t go on an angular yellow and grey leaflet or business cards.
However it also needs to be remembered that your logo will almost always be in a context. For example on a website, leaflet, poster, etc so it doesn’t need to “say everything”. Indeed typically trying to “say everything” results in a cluttered logo with every aspect so over-thought that the average person just won’t “get it” in the glance they give it.
What should a church logo convey?
They two key things a church logo (and indeed any logo really) needs to convey is the name and an indication of the “style” of church (denomination). The “strapline” probably isn’t necessary at all or needs considering separately as these things usually change more frequently.
While “St Luke of the Martyr” and “Olive Grove International” might clearly indicate to Christians, it isn’t as obvious to someone who wants to try church after a long period away. That doesn’t have to mean “traditional imagery” and “funky young person” respectively, though if it helps be immediately obvious then go for it.
In this more global world people often search for a church, eg. the one they pass every day on the way to work. So having your location, eg. a post code or city name (if unique) instantly solves the issue of “is this the right church?”.
Have some logical fun!
No logo will be universally loved, and making a change from what you’ve already got which is “good enough” will always cause issues.
So while personal preferences should definitely be used included in the inspiration at the start ideally it should be possible to explain why a colour and shape has been chosen.
To keep it fun, we strongly recommend not having a “design committee” but just a couple people who have the necessary authority (or delegated authority) to take it on.
Otherwise you’ll get nowhere and it will take the joy out of it, trying to incorporate the views of every church member resulting in a mish-mash rather than a clear brand.
