— Aurelius Augustinus early Christian theologian and philosopher 354 - 430
Context: God is one, and the Church is a unity; only unity can respond to him who is one. But there are some people why say, “Yes, that certainly was the case. The Church spread among all nations did respond to him, bearing more children than did the wedded wife. It responded to him in the way of his strength, for it believed that Christ had risen. All nations believed in him. But that Church which was drawn from all nations no longer exists: it has perished.”
So say people who are not within the Church. What an impudent assertion! The Church does not exist because you are not in it? Be careful lest such an attitude result in your not existing yourself, for the Church will be here even if you are not. But the Spirit of God anticipated this abominable, detestable assertion, this claim full of presumption and falsehood, a claim with nothing to support it, illumined by no spark of wisdom, seasoned by no salt. God’s Spirit anticipated this empty, unfounded, foolhardy and pernicious proposition and seemingly refuted it in advance by proclaiming that the Church is united by the gathering of the people together into one, and kingdoms to serve the Lord.
