How do you think the divisions of the christian church into clergy and laity them spread their beliefs?

The division of people into clergy and laity means that there are some people who only and exclusively worked in benefit of religion: those could then travel to other places and preach religion, and this would lead to the spread of their religion.

Clergy and Laity are those groups of people that completely have an absence of knowledge about bible. Christians find a way to help clergy and laity to realize that the bible exists and that God exists. Because of their undying help , it resulted to the reformation and renewal of some of the clergy and laity. Christian church organized a talks that is about their belief and show that they shared and spread it to the world. The growing of faith from the two groups then started to grow.
