Can one lose the title used by clergy in your religion?

If a member of your clergy stops fulfilling the role of clergy, do they still use the title for clergy in your religion?

As an example, the Jewish clergy are Rabbis. If someone receives rabbinical ordination, they are a Rabbi, even if they stop (or never begin in the first place) acting as clergy. The title is not dependent on them being clergy, merely whether they have been ordained.
