30
The Disciples Of Jesus started teaching people the ways of Jesus and This got more and more people and spread out from the middle east
Jesus did not have to learn anything.
The ideas of Christianity started in Judea with the teaching of Jesus Christ.
dear friend it is beleived that jesus was aound 30 years old when he started to heal people and thanks for asking the question
Jesus quoted from 24 different Old Testament books. The New Testament as a whole quotes from 34 books of the Old Testament Books. Many of of the teachings of Jesus often expand and define the meaning of the Old Testament such as found in the teaching from the Sermon on the Mount after quoting the key passages.
The first Christians were, if you believe the bible, Jesus's disciples, so Christianity began the year Jesus started teaching. If you count 0AD as Jesus's birth then about 20/21AD
It started after the death of Jesus Christ.
The common man and the gentiles liked Jesus and his teaching.
When he got his bachlors in teaching
Jesus' style of teaching was often through parables, using simple stories or analogies to convey deeper spiritual truths. He also used direct questions and discussions to engage with his listeners and provoke deeper thought and self-reflection. Additionally, he emphasized love, compassion, and forgiveness in his teachings, encouraging his followers to live with faith and humility.
He only started healing when he died on the cross. There you have it, 2 billion copies of the Bible.
It is thought he was 30 years when he started his work. But please note he is ageless.
