Translation of "Sect" in Japanese

I didn't know that depending on which sect they belong to, priests don't necessarily have to shave their head.

宗派によっては、お坊さんは坊主にしなくてもいいんだってね。知らなかったよ。

There are situations where you return to secular life of your own volition, and there are situations where the religious sect forces you to return to secular life.

自らの意志で還俗する場合と、教団側から還俗させられる場合がある。
