Churching the unchurched is an absolute fallacy – it is like purposing to let the tares in. It is absolutely bizarre to want to make unsaved people feel comfortable in a church. The church is not a building – the church is a group of worshiping, redeemed, and sanctified people among whom an unbeliever should feel either miserable, convicted and drawn to Christ, or else alienated and isolated. Only if the church hides its message and ceases to be what God designed the church to be, can it make an unbeliever comfortable.
John MacArthur
