Existence of Jesus, as he is described in the Gospels, is the matter of faith.
In many ways, yes. Faith is required to believe repentance for the forgiveness of sins, that the reign of God is in our midst, that is one with God are matters of faith. He was also an historical person.
Well, putting aside his very specific birth, he never identified himself as a Jew, neither associated himself with the Jewish people in any form. He never said even one good word about the country, the Jewish people, their history, traditions and religion. He never said "we", but rather "you".
The most important issue of his time was the Roman occupation. He said nothing against it.
Yes, the Gospels did identify Jesus as a Jew, and his entire ministry was amidst Jews. His closest associates were Jews. When talking to Jews, he called them the salt of the earth.
OK, somebody disliked an existed religion and created his own religious sect. Quite an ordinary event.
Jesus loved the purity of the Jewish faith, and how it dealt with personal relationships. His interest did not lie in Messiahship, kings, and emperors, but how individuals related to God and to one another. That was the Kingdom that occupied his thoughts and his ministry.
I meant the words of Jesus in the Gospels.
Also, Jesus called his followers "the salt of the earth".
How individuals related to God and to one another was written in Torah more that 1000 years before Jesus birth.
According to the Gospels he did have interest, putting himself between God and people.
Jesus was born into this world to testify to the truth. Everyone who loves the truth, loves Jesus.
“But when the fullness of time had come, God sent forth his Son, born of
woman, born under the law, to redeem those who were under the law, so
that we might receive adoption as sons.” Gal 4:4
And without controversy great is the mystery of godliness:
God was manifested in the flesh,
Justified in the Spirit,
Seen by angels,
Preached among the Gentiles,
Believed on in the world,
Received up in glory. 1 Timothy 3:16
The Word became flesh and made his dwelling among us. We have seen his glory, the glory
