What if a church near me uses the same template as me?

First of all, using a bespoke banner or set of rotating images can set your site apart from others using the same template.

But there is a bigger question here that we would do well to answer: Does it matter if another local church nearby has a similar site design to yours? We have to remember that churches don't (or at least, shouldn't) compete with one another. We are part of a kingdom, not a competition.

Here's a similar example of what we're talking about. Football teams don't go competing to lure fans to switch teams because the supporters are normally loyal to their local team. That's why you can look at the English Football Championship League where all the teams in the league use the same template design and just put in their own branding and content. So whereas Nottingham Forest and Derby County are only a few miles away from each other, it doesn't matter that they use the same template for their website! Churches, too, don't have to compete to get people into their churches, so why should it matter that two nearby churches share the same template?
