It isn't really much of a parallel-
It would be more parallel to a pastor on a two-term call that could be renewed, wishing and hoping that the congregation renew the call.
The pastor waiting for the call should hope for it if s/he believes it to be the will of God. What s/he should NOT be doing is blabbing to the local Newspaper about what s/he will be doing when called to that parish.
In the case of extending a term-call, I think that a pastor would announce his/her desire to the congregation and others that s/he was willing to continue serving that congregation.
As one who has just received a Call (at least on the phone, waiting for the paperwork,) I did not announce it to the congregation until it was a done deal -- actually, I
will be announcing it on Sunday, although I have told close friends in the congregation, and the council and have submitted my letter of resignation to the council president.
