Judaism was practiced by Jews under the law of Moses which was the Old Testament Covenant, Jesus the Lamb of God kept the law perfectly, it was no longer needed.
After Jesus death, burial and resurrection, be brought in New Living way, John the Baptist says it in Matthew 3:11, Christianity came about at the sending of the Holy Spirit on Day of Pentecost in Acts 2:4.

No! Christianity didn't come at the sending of the Holy Spirit; the Church was born at the sending of the Holy Spirit.
Christianity developed as a result of the Church becoming an organization. Organizations need regulations, rules, laws, ordinances, etc.
People don't feel safe without rules and regulations. The rules and regulations preceded the Church becoming an organization. It was inevitable.
When the Holy Spirit was given on the Day of Pentecost, there were around 3,000 individuals who were endowed with the Spirit of God. They had only that in common. They were called out of the world; they were the ecclesia; they were a congregation, an assembly of new believers in Jesus as the Savior of the world.
Naturally, they assembled. When they assembled, naturally they organized; when they organized they became an organization. All they were missing was a name for themselves and a secret handshake.
Someone in Antioch started calling them "Christians" as a put down. It stuck because they saw it as honoring to Jesus to be willing to be shamed for his sake.
The name recognition of "Christians" led to the belief system being called Christianity. It took years for all of that to evolve. The word 'Christian' was never uttered by Jesus.
The word 'christian' appears 3 times in the whole Bible (Acts 11:26, Acts 26:28, and 1 Pet 4:16); the word 'Christianity' isn't in the Bible anywhere. That means it's the work of religious organizers.
They skipped the handshake...

Consider this if you will:
Christianity could easily have been scrapped for the term "Discipleship." Christianity has more of an organizational sound to it, I think.
If you abide in my word, you are truly my disciples (John 8:31), instead of 'If you abide in my word, you are TRULY CHRISTIANS.'
By this all people will know that you are my disciples, if you love one another. (John 13:35) He didn't say 'all people will know that you are Christians.' I think he prefers to call his followers 'disciples.' (he even called us 'sheep,' but not 'Christians.')
"I have other sheep that are not of this fold..." John 10:16 He said he would lay down his life for "the sheep." John 10:15. (the New Testament contains 45 references to 'sheep.')
Jesus was well aware of what his followers would be called after he returned to the Father.
The word 'disciple' appears 261 times in the New Testament. The word 'Christian,' only 3 times.
Which title for us seems to be the Lord's choice? My guess is 'disciple.' Or maybe 'sheep.' I call myself a believer. 'Christian' sounds a bit political to me... but that's just me...
