a question about Jesus and Christianity?

Well for starters during the time of Jesus' public ministry there were already many different Jewish sects the ruling sect were the Pharisees. These different sects debated over beliefs with good reason the traditions of these sects were misplaced and even in Scripture it states that for a time the Torah was lost to them. So what does that say about the various Talmuds the oral traditions?

2 Kings 22:8-11

The high priest Hilkiah informed the scribe Shaphan, “I have found the book of the law in the temple of the LORD.” Hilkiah gave the book to Shaphan, who read it. Then the scribe Shaphan went to the king and reported, “Your servants have smelted down the silver deposited in the temple and have turned it over to the master workers in the house of the LORD.” The scribe Shaphan also informed the king, “Hilkiah the priest has given me a book,” and then Shaphan read it in the presence of the king. When the king heard the words of the book of the law, he tore his garments.

Christians believe Jesus is the Word made flesh, God incarnated as Man. Therefore what Jesus taught was not the same as what was taught by these various sects of Jews. The disciples of Jesus would be called the Christians.

A religion is a distinct set of beliefs which defines it. Christianity, Judaism, Islam, Hinduism, Buddhism, etc., etc.... are religions they are distinctly different in their beliefs which defines each one of them.

Jesus did not start any religion. In fact, Jesus was against religion. Jesus liberated the oppressed Jews from the religion of Judaism. Jesus did not start the religion known as Christianity. The religion Christianity is not based on the teaching of Jesus. The teaching of Jesus is recorded only in 4 books of the Bible - Matthew, Mark, Luke and John. Jesus taught us about God, God's kingdom and about the way to earn our citizenship of God's kingdom. Jesus taught us that only by doing what God wants us to do here on earth, we can inherit God's kingdom. God loves this world very much. He expects us to love this world and make it a better place for humanity.

Christianity was not a totally new religion with the outpouring of holy spirit on Pentecost 33CE. Its roots lay deep in the religion of the Israelites, nourished by the written Law of Jehovah God. Even before Israel became a nation, worship of Jehovah was practiced by their forefathers Noah, Abraham, and Moses and was actually a continuation of the oldest religion in existence, the true worship of the Creator as initially practiced in Eden. But the national and religious leaders of Israel allowed false religion with Babylonish overtones to seep into their worship and thus pollute it. The Jewish congregation at the time of the birth of Jesus was fouled with hypocrisies and cluttered with a formalism that obscured the underlying spiritual truths uttered by the great Hebrew prophets.

Compared to the human complexities tacked onto the Jewish faith, Jesus’ teachings were marked by simplicity. Paul, one of Christianity’s most energetic first-century missionaries, showed this when he spoke of Christianity’s main qualities: “There remain faith, hope, love, these three; but the greatest of these is love.” (1 Corinthians 13:13)

Jesus emphasized the need to “exercise faith in God,” the One he described as the Creator. (John 14:1; Matthew 19:4; Mark 13:19) So Christianity differs from Jainism and Buddhism, both of which reject the idea of a Creator, claiming that the universe has always existed. And since Christ spoke about “the only true God,” he clearly did not believe in a multitude of true gods and goddesses as the religions of ancient Babylon, Egypt, Greece, and Rome taught, or as Hinduism still teaches.—John 17:3.

The divine purpose, Jesus explained, was that he give ‘his soul as a ransom in exchange for many,’ to “save what was lost,” so that “everyone exercising faith in him might not be destroyed but have everlasting life.” (Mark 10:45; Luke 19:10; John 3:16; compare Romans 5:17-19.) Belief in a sacrificial death to accomplish atonement from sin differs from Shintō, which refuses to acknowledge that original or inherent sin exists.

Jesus taught that there is just one true faith. He advised: “Go in through the narrow gate; because broad and spacious is the road leading off into destruction, and many are the ones going in through it; whereas narrow is the gate and cramped the road leading off into life, and few are the ones finding it.” (Matthew 7:13, 14)

In his last statement to his disciples when he told them to go into all the world and teaches the things that Jesus had begun to teach them. He formed a new covenant then with the Gentiles (all the world) which is different from the old covenant that God had only with the Jews. You will find the statement in closing verses of Matthew chapter 28.

When he gave the "Great Commission"!

To knit pick- religion is an institution, Jesus and God are against institutional religions because they do not meet a real spiritual need. It was not actually a new religion because it is just a new contract for those that seek to please God. The more legal term is "covenant" and there are small differences between what the two mean.

He didn't. What HE did tell His followers to do was, first, to go to the lost sheep of Israel, to tell them the good news of the nearness of the Kingdom of Heaven - to begin gathering Jesus' little flock (the Jewish people). That is in Matthew 10:5-10.

Jesus also said in Luke 19:10 that He had come to seek and to save what was lost, beginning with the lost sheep of Israel. And in John chapter 10 He expanded on that; He has other sheep, not of that fold; they must all be gathered into one flock, with Himself as their one Shepherd. In John 12:42 we learn that many Jews would not follow Jesus openly for fear of being put out of the synagogue, and so it turned out. All Jewish people who confessed Christ found themselves put out and so their faith resulted in a distinct religion, disowned by Jews and Gentiles alike. Why, even the Romans thought the first Christians were atheists, and that idea appalled them! Of necessity, a distinct religion was identified - by others. The unique claims of Christ allow for no other possibility. Christianity is unique because Jesus Christ is unique. As Christians carried out Jesus' command in Matthew 28, to go to all nations, teaching and baptizing, Christianity burst upon the world stage. But it's not religion we promote - it is Christ.

He didn't. That was Peter and Paul and James who started the new religion, not Jesus.

He never mentioned religion in the Bible.

He asked his disciples to go into all the world and preach the gospel.

A prescription for worship of the one true and eternal God is not a prescription for a new religion. It is a prescription for the singular true and eternal religion of God.
