some of them deny his resurrection, others didn't believe that he was divine, others separate Jesus from God and he was a man and he became God or something like that, and the catholic councils fought against those ideas like arranism.
There were hundreds of people all claiming to be the messiah at the time. All records of Jesus were written many years after his supposed death and far from where Jesus lived. While there were many people named Jesus at the time, none of them were the Jesus described by the Bible.
Jesus came from this lineage, Matt.1:1-17, Abraham was son #20, years 2008
to 2183, David was son #33, years 2959 to 3029, son # 47 died by the time
Babylon took over, year 3460[ 606 BCE, 14 generations to Jesus son #61 of
Matt.1:1-17]; Babylon ended all they had had, since Moses at 430 years after
Abraham was age 75, and in 40 years after Exodus, Deut.34:7, had them in
their own land, and then he died, they had the law that would lead to Christ
Jesus, Gal.3:16-26; the Lord and Savior of all lineages or all the of-springs of
Adam, 1Cor.15:22-28,51-53,"As in Adam all die, even so in Christ shall all be
made alive," heavenly redeemed are made alive first to be with Jesus at his
2nd coming, Jesus was with God before the world was, John 17:1-26, he was
with him at Gen.1:26, or at Gen.11:7[all other angels see all done before Gen.
1:26, at Adam, as they were there before him, Job 38:4-7, 30-32], he came
to earth, and ascended back to his God and Father, John 20:17, John 3:13-
15, as he was ascended when all about him was written in the New
Testament, after they were anointed from Pentecost, the anointed will be with
him in heaven as they keep the word of God alive and flowing, to the time of
the end, Matt.24:3,7,14,15, the coming kingdom is made known to the whole
world, then the world ends, at his 2nd coming, Rev.20:1-6, no Satan, the
world ended, and theheavenly are with him at his 2nd coming, to resurrect
all on earth from the dead, until all evil is gone, Rev.20:7-10[19:20]. The new
earth is cleansed, Rev.21:1-5, at 21:8, all evil humans devoured.
