Anti-religious people lack faith in the power of the Holy Spirit. They don’t believe in the power of the Holy Trinity, nor do they believe in Christian salvation history. In most cases, they don’t want to be reminded of the 10 Commandments or of personal judgement by a Deity.
The beautiful truth about Judaism and the Early Church is the ability to pass the faith to their children and to converts through oral traditions.
(Anti-religious hate this because their minds only accept what they can see, touch, smell, feel, hear). They need physical proof of the existence of God.
Jews had a systematic life that centered on advancing Judaism. God the Father was central to their life, work, holidays, ceremony, liturgy, daily commands, etc. They lived their faith in totality. It wasn’t an extra thing tacked onto one particular day.
That’s important to know, because oral tradition overcomes a lack of education, a lack of writing materials, a lack of ability to read.
When a faith extends out to converts (who don’t live in community) or don’t speak the language (Hebrew) then it becomes neccessary to translate the oral knowledge or to form a Church where the faith can be passed orally through a homily.
Early Christianity also primarily spread the faith through oral tradition.
As society advanced, (with increased education, translation advancements, availability of less expensive writing materials) Christianity spread.
However, Scripture also needed an atmosphere of acceptance. It’s very difficult to write, rewrite, and protect Scripture through paper means when the Churches and the early Christians were being imprisoned and martyred for their faith.
