One Interpretation the Powerful Won't Allow
The logical conclusion is that the Jews were already saved by God the Father through Abraham and Moses. Jesus was sent to save the Gentiles, not to convert the Jews, St. Paul was directed to make the branch religion compatible with Roman tastes.
Anti-semitism is not derived from religion; it is a weapon of the ruling class to blame others for what decadent self-appointed leaders always do themselves.
Jesus came to only preach his gospel unto the House of Israel. For this reason he taught his disciples the following:
Matthew 10:5-7
5 These twelve Jesus sent forth, and commanded them, saying, Go not into the way of the Gentiles, and into any city of the Samaritans enter ye not:
6 But go rather to the lost sheep of the house of Israel.
7 And as ye go, preach, saying, The kingdom of heaven is at hand.
Jesus specifically command his apostles not to teach among the Gentiles and Samaritans but only to the lost sheep of the House of Israel. Another example of this is when Jesus spoke to the Canaanite woman who wished for him to heal her daughter.
Matthew 15:21-28
21 Then Jesus went thence, and departed into the
coasts of Tyre and Sidon.
22 And, behold, a woman of Canaan came out of the same coasts, and cried unto him, saying, Have mercy on me, O Lord, thou Son of David; my daughter is grievously vexed with a devil.
23 But he answered her not a word. And his disciples came and besought him, saying, Send her away; for she crieth after us.
24 But he answered and said, I am not sent but unto the lost sheep of the house of
Israel.
25 Then came she and worshipped him, saying, Lord, help me.
26 But he answered and said, It is not meet to take the children’s bread, and to cast it to dogs.
27 And she said, Truth, Lord: yet the dogs eat of the crumbs which fall from their masters’ table.
28 Then Jesus answered and said unto her, O woman, great is thy faith: be it unto thee even as thou wilt. And her daughter was made whole from that very hour.
Here Jesus clearly teaches the Canaanite woman in verse 24 above that He is not sent but unto the lost sheep of the house of Israel. Eventually Jesus healed her daughter because of her great faith in him, but at first He never answered her a word. While Jesus was here on the earth, his mission was unto the lost sheep of the House of Israel. It was not until after his death and resurrection and ascension into heaven that he had the gospel preached unto the Gentiles.
Acts 10 tells how it came about that the gospel was eventually taught among the Gentiles. In the days of Jesus and his Apostles, the gospel was to go first to the Jews and then to the Gentiles. However, in these latter-days, the gospel was to go first to the Gentiles and then to the Jews. The first shall be last and the last shall be first.
