Ask yourself why the Jews were hated. Were they hated because they were innocent or was there a legitimate reason?
See my post above.
Martin Luther called the Jews the worst enemies after the devil. Why did he call them that?
That's a good question. Luther certainly did say some awful things near the end of his life. He was a man of God, but also a sinner, which doesn't excuse him, certainly, but accounts for why he said some awful things. And even so, that doesn't somehow negate or tarnish or invalidate the great things he had done earlier in his career for the sake of the spread of the Gospel, it just exposes him as a flawed sinner, like all us men (and women) are.
Why were the church fathers and the Reformers anti-Judaists?
The leaders of the Reformation were not, they were quite the opposite. Not sure who you mean by "church fathers."
Why was the Apostle Paul an anti-Judaist?
He was certainly not. Since God is the ultimate Author of His Word, you might as well ask if God Himself is an "anti-Judaist," which is absurd.
He called the Jews enemies of humankind. Why?
No, in Romans 11, Paul says (and I quote),
"As regards the gospel, they are enemies for your sake. But as regards election, they are beloved for the sake of their forefathers..." Which is to say, John839, that the
unbelief of ethnic Israel has
benefited the Gentiles, i.e., this is the period of history in which Gentiles are being saved, while most ethnic Jews remain in unbelief. But God's electing promise given to their forefathers Abraham, Isaac, and Jacob
will be fulfilled in the future. So ethnic Jews are
not "the enemy of humankind"... Paul calls them no such thing, but rather
enemies of the Gospel ~
unbelievers ~
for the sake of the Gentiles... for a period, until the full number of elect Gentiles is brought in to God's Israel, at which time the partial hardening on Israel will be removed and thus all Israel will be saved. If you read this correctly, you will understand that when you see ethnic Jews coming to Christ at a great rate, even enmasse, you will know that the fullness of the Gentiles has been brought in and the time of Christ's return is very near, even to us from our own perspective. You see?
Why was Jesus an anti-Judaist?
Can a Jew be anti-Judaist? <chuckle> I mean, it was His custom to observe the Sabbath in the synagogue (Commandment 4) in every town he came to, so it certainly seems not, right? Actually, I'm not even sure what you mean by "anti-Judiast"... :) Anyhoooo... Jesus is God made man, of course, and we know that God desires that all would come to knowledge of the truth ~ and Jesus Himself is the way, the truth, and the life ~ and thus be saved. So I guess you could say He is "anti-Juda
ism"... in the sense that Judaism is rejecting of Jesus as the Messiah and thus
false Judaism, in the sense of who true Jews really are and who God's Israel really is, as Paul shows us in Romans 2:28-29...
"For no one is a Jew who is merely one outwardly, nor is circumcision outward and physical... (b)ut a Jew is one inwardly, and circumcision is a matter of the heart, by the Spirit, not by the letter... his praise is not from man but from God."
He called the Jews children of the devil. Why?
Because they ~ not all Jews, but the ones there at the Feast of Dedication ~ were imploring Him to tell them directly (again, because He already had) if He was the Christ. And what He said in response was,
"You do not believe because you are of your father the devil." In other words, their not being among His sheep was
because the Father had not given them to Him, because their father was not Abraham but rather the devil... i.e., they were
unbelievers, which all children of the devil are. And even on top of that, in our
natural state ~
unless and until we are born again of the Holy Spirit ~ we are
all children of the devil. So, as Paul says in Ephesians 2:4-10...
"But..." ~ BUT, the most glorious 'but' in all of scripture <smile> ~ "...God, being rich in mercy, because of the great love with which He loved us, even when we were dead in our trespasses, made us alive together with Christ ~ by grace (we) have been saved ~ and raised us up with Him and seated us with Him in the heavenly places in Christ Jesus, so that in the coming ages He might show the immeasurable riches of His grace in kindness toward us in Christ Jesus. For by grace (we) have been saved through faith. And this is not (our) own doing; it is the gift of God, not a result of works, so that no one may boast. For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them."
And this properly applied to believing ethnic Jews as well as Gentiles ~ all believers of every tongue, tribe, and nation... all of God's elect.
Grace and peace to you.
