not according to jesus and his reference to leviticus 19...
it starts our with god saying...
vs. 2 Speak to the entire assembly of Israel and say to them: Be holy because I, the LORD your God, am holy.
neighbor in this context was meant for the jews who were apart of the assembly of israel...not anyone and or everyone...
as for jesus...matthew 10
vs 6 Do not go among the Gentiles or enter any town of the Samaritans. 6 Go rather to the lost sheep of Israel. 7 As you go, proclaim this message: The kingdom of heaven has come near. 8 Heal the sick, raise the dead, cleanse those who have leprosy,[a] drive out demons. Freely you have received; freely give."
freely give to the lost sheep of israel...not anyone or everyone.
No, these verses show the specific missions that Jesus was given and had to give to His disciples at the time. The people of Israel were first on the agenda, because they were the "lost sheep", and God's chosen people, and should be preached to first. There were also practical reasons; who knew what kind of carnage may occur if the disciples preached to the Gentiles first, and the Jews found out that these disciples were preaching to all their neighbours "false" versions of their own faith? They wouldn't be happy, and would in future be more resilient against any conversion attempts. Thus, it would be safer and better to preach to the Jews first.
Jesus never directly specified who someone's neighbour was, and if His message was not for the Gentiles he would have made it clear.
Some say that Jesus "realised" sometime in his ministry that His message was for the Gentiles as well. I have doubts about that, but here are the Bible verses that support this argument.
Matthew 15:21-28
21 Leaving that place, Jesus withdrew to the region of Tyre and Sidon. 22 A Canaanite woman from that vicinity came to him, crying out, Lord, Son of David, have mercy on me! My daughter is demon-possessed and suffering terribly. 23 Jesus did not answer a word. So his disciples came to him and urged him, Send her away, for she keeps crying out after us.
24 He answered, I was sent only to the lost sheep of Israel.
25 The woman came and knelt before him. Lord, help me! she said.
26 He replied, It is not right to take the childrens bread and toss it to the dogs.
27 Yes it is, Lord, she said. Even the dogs eat the crumbs that fall from their masters table.
28 Then Jesus said to her, Woman, you have great faith! Your request is granted. And her daughter was healed at that moment.
It shows that God had specified Jesus to be sent to the Israelites and preach among them, and His testing of the Canaanite woman shows that while Jesus was sent to the Jews, His entire teachings were for everyone, and praises the Canaanite woman's faith.
Now, elsewhere in the Bible, it also states clearly that the Message is for the Gentiles. Jesus was sent by God to save the Jews and begin preaching the new message of salvation. His disciples are then commanded to carry on his work, but this time to the Gentiles as well:
Acts 13:47 "The Lord has commanded us, saying, I have set you to be a light for the Gentiles, that you may bring salvation to the uttermost parts of the earth"
Rom. 10:12 For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him.
Everyone is our neighbour. There is no difference between them, and the Bible never specifies who is our neighbour, so you cannot come up with such an assumption that it does.
