The first teacher was Jesus Christ. He prepared the apostles to preach the Gospel. Then prepare for the priesthood, took various forms. In the first centuries of Christianity, it was important ascetical and spiritual preparation for the priesthood. Appropriate knowledge and holy life – it was a program to prepare for the priesthood. Created a community where young people prepare for the priesthood.
