Any church that will not accept that it consists of sinful men and women, and exists for them, implicitly rejects the gospel of grace. As Hans Kung say, “it deserves neither God’s mercy nor men’s trust. The church must constantly be aware that its faith is weak, its knowledge dim, its profession of faith halting, that there is not a single sin or failing which it has not in one way or another guilty of. And though it is true that the church must always disassociate itself from sin, it can never have any excuse for keeping any sinners at a distance. If the church remains self-righteously aloof from failures, irreligious and immoral people, it cannot enter justified into God’s kingdom. But if it is constantly aware of its guilt and sin, it can live in joyous awareness of forgiveness. The promise has been given to it that anyone who humbles himself will be exalted.”
