Last November, my Bishop appointed me to serve as the Dean of the Deanery in which my parish is located. That meant there was going to be a modification of my coat of arms. The addition of a second tassel to the galero in my armorial bearings was for the duration of the office of Dean only.
Just yesterday, my Bishop announced the appointment of three new Deans. Two of them are appointed to fill vacancies created by the retirement of two priests. The third is in my own Deanery where a vacancy is about to occur when I am transferred to a new assignment later this month. Since the extra tassel was only “pro hac vice” I must now reliquish it and revert to using the galero of a simple priest, with one tassel pendant on either side of the shield.
As it turns out, I served as a Dean for only nine months. At the time of my appointment last November, my bishop and I had no way of knowing that I would be transferred only the following summer.
EXARANDORUM 
Sic transit gloria mundi. I hope that a return to parochial status is good for you and for your people.
Thanks. I never actually left parochial status. I served as Dean in addition to being Pastor of my parish.
Good luck with the new assignment!
Thank you.
I hope that your new assignment goes well.
In todays church we have new titles: directors, coordinators, etc that are bestowed on priests many times as part of their work in a diocese: is it time to allow for these positions to be represented in their CoA?
No. It isn’t. Heraldry in the Church primarily concerns itself with the rank of the armiger rather than a function. This comment is on a post about how I had been the Dean and was now moving and so relinquishing that rank. The rank of Dean (sometimes called Vicar Forane is, like Vicar Episcopal, or Vicar General) a canonical office in which the holder shares in the authority of the Bishop. It’s not merely some task or diocesan job given to a priest. Such jobs differ hugely in name, in function and in job description from diocese to diocese. Canonical offices do not. They exist throughout the whole Universal Church. In addition, the Church primarily concerns itself with the external ornaments of heraldry, rather than what is on the shield. So, for example, as a Dean my arms remained the same but the external ornament of the galero had an additional two tassels pendant from it and only for the time that I was in that office. A pastor may impale his personal arms with those of his parish to show that he has jurisdiction over that parish. But, he hasn’t modified his coat of arms. Rather, he simply marshals them in order to display two coats of arms side-by-side on the same shield. But, note that there is no special galero to denote that one is a pastor as opposed to another priest. Pastors and Parochial Vicars are of the same priestly rank, but one has jurisdiction while the other does not. One of the jobs that I do for my diocese is Director of Ecumenical & Interfaith Affairs. There is absolutely nothing whatsoever that indicates that heraldically, nor should there be. The differences in ecclesiastical heraldry in the Catholic Tradition reflect different ranks not different jobs. Once, a priest who served his diocese as Chancellor (a position that is not necessarily a clerical office but may be held by a layperson) asked me if there were some special external ornament he could add to his coat of arms to indicate this. I told him no because that was a function he performed but it didn’t change his rank in the clergy. So, no, the different jobs that are often given to clergy do not need to be represented heraldically. Only a change in rank needs to be indicated by heraldic ornaments and additaments. An individual cleric may assume a coat of arms containing a charge that indicates some office held but that would then be superfluous once he no longer held the office. Similarly, he could augment his coat of arms by the addition of some element to allude to the office but, unless he removed it again when the office was no longer held, it would seem pointless and inappropriate.
