“Therefore Christ says here: ‘You seek to kill Me, because My Word finds no place in you. Whence comes this sin, that you begrudge Me My life and want to take it from Me? Could you be free and rid of sin? Is it possible that you are Abraham’s seed? No, you must be God’s enemies and murderers. You are motivated by the foremost sin, enmity toward God. If you were well-disposed toward God, you would also be well-disposed toward Me. My Word finds no place in you. To be sure, God’s Word does assail you; but you do not mend your ways. I am catching nothing with My net. Indeed, I cast My Word among you; but you are averse to it and hostile to God. It follows that since you hate My Word and oppose it, you must also be hostile to Me. God has the advantage that you cannot kill Him. Me, however, you can kill, since I am mortal.’ Therefore an unbeliever is a murderer of God and of man, whether he be called Abraham’s seed or anything else. For if he could kill God, suppress the truth, and exterminate the divine Word, he would do so. Subsequently he also becomes a murderer of man.
This sermon is directed against the boasting of the Jews, who assumed that they, as Abraham’s seed, could not perish. Gross arrogance is now making itself felt in the papacy, yes, also among us. Many of us say boastfully: ‘We are evangelicals; we have learned this doctrine well.’ They brag that everything they do is right. They expect the Gospel to yield to their pleasure, just as the Jews supposed that because they were Abraham’s seed they could do as they pleased. The pope and the bishops also believe that their Baptism authorizes them to do as they choose in the church and in Christendom” (Luther’s Works, v. 23, p. 418).
