This type of structure of religious services is common to practically all known religions, insofar as the different levels of preparation of the clergy are not accessible in all the centers, but only in the central institutions (Rome, Tibet, Tel Aviv, Mecca). It is where the missionaries, the monks or priests can receive the ordination of the highest level.

With regards to the religious community of Scientology, they form a real community of ministers and religionists, who live in community, with a total dedication to the purposes of the Church and with abandon of worldly interruptions and vanities.
