From the ichthys1 to the cross, symbols have been a part of Christianity since ancient history. Modern churches make great effort to connect with that history, while still reaching out to the modern parishioner. Enter: the church logo.
There are as many ways to approach logo design as there are to approach your faith. It’s hard to even say one logo is “better” than another. As long as it conveys the message of your congregation, then it’s the right logo for you.
