Romans 2:28-29, “For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh: But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God.”
Romans 11:11-31
11 So I ask, did they stumble in order that they might fall? By no means! Rather, through their trespass salvation has come to the Gentiles, so as to make Israel jealous. 12 Now if their trespass means riches for the world, and if their failure means riches for the Gentiles, how much more will their full inclusion[
a] mean!
13 Now I am speaking to you Gentiles. Inasmuch then as I am an apostle to the Gentiles, I magnify my ministry 14 in order somehow to make my fellow Jews jealous, and thus save some of them. 15 For if their rejection means the reconciliation of the world, what will their acceptance mean but life from the dead? 16 If the dough offered as firstfruits is holy, so is the whole lump, and if the root is holy, so are the branches.
17 But if some of the branches were broken off, and you, although a wild olive shoot, were grafted in among the others and now share in the nourishing root of the olive tree, 18 do not be arrogant toward the branches. If you are, remember it is not you who support the root, but the root that supports you.

Jesus Himself:
Matthew: 21
33 “Listen to another parable: There was a landowner who planted a vineyard. He put a wall around it, dug a winepress in it and built a watchtower. Then he rented the vineyard to some farmers and moved to another place. 34 When the harvest time approached, he sent his servants to the tenants to collect his fruit.
35 “The tenants seized his servants; they beat one, killed another, and stoned a third. 36 Then he sent other servants to them, more than the first time, and the tenants treated them the same way. 37 Last of all, he sent his son to them. ‘They will respect my son,’ he said.
38 “But when the tenants saw the son, they said to each other, ‘This is the heir. Come, let’s kill him and take his inheritance.’ 39 So they took him and threw him out of the vineyard and killed him.
40 “Therefore, when the owner of the vineyard comes, what will he do to those tenants?”
41 “He will bring those wretches to a wretched end,” they replied, “and he will rent the vineyard to other tenants, who will give him his share of the crop at harvest time.”
- Talking about after his own death.
- The only thing you were remotely correct about was him not having Gentiles within His immediate company, but the Samaritan woman was forgiven of her sins - and wasn't Jewish.

And, furthermore, in Acts, at the outpouring of the Holy Spirit, Gentiles began to manifest the gifts of the spirit that Jesus told His disciples would come.
- In short, know what you're speaking of.

Now, why did I bring that up? The Orthodox church believes much of this and explained it rather well to me when I met some of them at a barber shop. So, please understand the concepts of the Orthodox church and, funnily enough, the Russian Orthodox church is likely closer to the original belief systems in regard to this. Sure, there's more pomp and pageant, but the actual beliefs ascribed DO come from Saul of Tarsus and so on. Also, fun fact, Russia has bishops blessing some of their ammunition, tanks, and missiles.
So, a history lesson and current events!
