I really had planned on writing a second post on this topic, talking about the horizontal implications of the Incarnation. Then I read this and decided I didn’t need to:
“Let the fellowship of Christ so examine itself today and ask whether, at the hour of prayer and worship, any accusing voices intervene and make its prayer vain. Let the fellowship of Christ examine itself and see whether it has given any token of the love of Christ to the victims of the world’s contumely and contempt, any token of that love of Christ which seeks to preserved, support, and protect life. Otherwise, however liturgically correct our services are, and however devout our prayer, however brave our testimony, they will profit us nothing, nay rather, they must needs testify against us that we have as a Church ceased to follow our Lord. God will not be separated from our brother: he wants no honor for himself so long as our brother is dishonored. God is the Father, the Father of our Lord Jesus Christ, who became the Brother of us all. Here is the final reason why God will not be separated from our brother. His only-begotten Son bore the shame and insults for his Father’s glory. But the Father would not be separated from his Son, nor will he now turn his face from those whose likeness the Son took upon him, and for whose sake he bore the shame. The Incarnation is the ultimate reason why the service of God cannot be divorced from the service of man. He who says he loves God and hates his brother is a liar.
There is therefore only one way of following Jesus and of worshiping God, and that is to be reconciled with our brethren. If we come to hear the Word of God and receive the sacrament without first being reconciled with our neighbors, we shall come to our own damnation. In the sight of God we are murderers.”
