A truly inclusive church can't afford to be so self-centred that it ignores or summarily dismisses other people's belief systems. There's a big difference in knowing what you believe, having a strong sense of corporate identity and treating other people's religious beliefs as inferior. Given the nature of faith, it can easily come off as arrogant to act as if we alone possess the truth about God and everyone else has got it wrong.
A truly inclusive church understands the importance of partnerships within a local community context and isn't afraid to talk and work with people of other denominations and other religious expressions. Too much blood has been spilt in religious wars for centuries and the natural consequence is for people to treat all religions that preach peace and wage war with suspicion. Let's see if we can find a different pathway forward.
