[[Dear Sister Laurel,
Are the rights and obligations you accepted with public profession in jeopardy should another Bishop come in? What I am thinking is what happens if a bishop comes in who doesn't believe there should be diocesan hermits? Would you lose your vows or your relationship with the Bishop?]]
No. While the more personal dimensions of the relationship between hermit and superior might be less than ideal in such a case --- especially in the beginning before the two people know each other better or, in particular, have had a chance to meet with each other one on one to discuss the vocation and how things are going with it, the hermit's vocation or vows are not in jeopardy simply because a new Bishop is installed. In my last post I noted that one of the relationships established in public vows was established between the Bishop, his successors, and the hermit. It is the office of Bishop in this specific diocese acting in the name of the whole Church which assumes a relationship of specific rights and obligations with regard to this hermit while the hermit herself assumes specific rights and obligations in regard to the local ordinary of this diocese via public vows --- whoever he is in the future. Should this Bishop move or retire, the rights and obligations of the hermit continue and the new Bishop assumes his predecessor's place in the legal (that is, canonical) relationship.
The hermit in perpetual vows, then, is not at risk of ceasing to be a diocesan hermit each time a new Bishop is installed. This is so even if that Bishop does not believe in the vocation and so forth. The situation with temporary vows differs somewhat, so let me make a bit of an excursus here. In such a case, there is a chance that the new Bishop would choose not to renew these vows once they had expired; temporary vows are made for a certain period of time and this remains a time of discernment for all involved. Should a new Bishop decide the vocation is wrong for the diocese at this time, find the person is not really called to either renewal of temporary vows (whether now or for some time period,) or to perpetual vows, then he has the right to refuse admittance to these and, when the vows expire, the person will cease to be a diocesan hermit. They would probably choose to remain a lay hermit in such a case, difficult as this might be for them in some ways but they would need to discern this step afresh. Also, one would hope that a Bishop coming into a diocese where there are diocesan hermits in temporary canonical (public) vows would himself act out of true discernment, and not out of bias of course, but the latter does remain a possibility.
My own vows however are canonical, perpetual, and were made to God in the hands of the Bishop as representative of the Church. He was acting in her name in receiving those vows, and so, his act binds the Church and the hermit in a new legal and public relationship. (At profession besides a copy of the vows signed and witnessed during the ceremony, I received a notarized statement verifying the public and perpetual nature of these vows signed by both the Bishop and the Vicar for Religious and Ecclesiastical notary.) Only the canonical dispensation of my vows for significant valid reasons can alter the relationships, rights, and obligations which obtain in public profession. Your question is really a good one because it helps outline the relative security of the relationship per se, as well as illuminating a piece of what we mean by initiation into a state of life. The Church defines consecrated life in part as involving initiation into the consecrated state achieved in a definitive (permanent, solemn, or perpetual) act --- that is, into a stable and lasting state where one dedicates oneself, is set apart (consecrated) by God and acquires rights and obligations which do not themselves flow directly from one's Baptism. Once this occurs, all parties are obligated to respect the relationships, rights, and obligations which obtain. In regard to your question this means any future Bishop coming into the diocese as pastor.
Your question also helps illuminate the importance of canonical standing (standing in law) for those called to it. In the case of diocesan hermits, the hermit does not, at least, have the insecurity of wondering if she will continue to be able to live her vocation freely or explore the frontiers of solitude in God as she has covenanted to do on behalf of others and in the name of the Church simply because the diocese is going to experience a change in personnel. There is plenty of insecurity in the diocesan eremitical life just as there is in any eremitical life, but this one particular bit is not an issue. The Church itself is bound to assist the hermit in this and bound in specific legal ways. Standing in law is not a bit of mere formality or icing on the eremitical cake; it sets up stable and lasting relationships which all involved are bound to observe for the good of the vocation generally, the person called to this vocation specifically, and the church herself.
What we must remember is that law is meant to serve love; it is also meant to provide freedom, because constraints can serve genuine freedom. In other words, canon law sets up a number of constraints for the diocesan hermit, but these tend to serve her well in freeing her to live a life of solitude without being concerned with explaining herself to those around her, or being threatened with the fear that perhaps she has mistaken how she is to participate either in the world around her or the life of the church. Law's obligations assist the hermit in living her life, not just moving through day by day wondering if she has yet discovered what that life is actually meant to be. It outlines and binds the hermit to a life of the evangelical counsels, to a Rule she herself writes and a Bishop officially decrees is acceptable for living this life, and to a number of other canons which apply to anyone with public vows, but the realm it sets up in doing so is one of life in God. While the parameters may function as constraints in one way, they are precisely the things which help the hermit to go deeper and to explore this particular country as freely and exhaustively as possible.
In a sense this is an outline of what monastic stability means. Monastics relinquish the right to simply go wherever the grass seems greener at the time in order to live as fully as possible with the grace of God right here in this place. Married persons do something of the same. They bind themselves to the constraints of a commitment to this other, this family, these specific needs, the potential and limitations of this series of relationships at this time and in this place so that they can live out this love as fully and exhaustively as possible in the way they feel called to by God --- something which must often be distinguished from what a person merely WANTS to do. It is the role of civil and canon law to protect this possibility. It is ironic that this freedom comes with the imposition of constraints, but that is always the way of true achievement and true freedom. Writers are bound to the constraints of language to produce something which is truly transcendent. Musicians are bound to the constraints and capacities of instruments, music notation, physical abilities of musicians, etc in order to do likewise. Canonical hermits have their call and response mediated by the Church and that mediation includes the establishment of parameters and constraints which free for genuine transcendence.
In any case, the answer to your question is no, diocesan hermits' vocations/vows are not in jeopardy merely because of changes in episcopal personnel precisely because the vows are public. The related canonical relationships are established with the Church as a whole but through the office of Bishop within a specific diocese. (Should the hermit desire to leave the diocese, she must receive approval from her own Bishop and the Bishop in the diocese she proposes to move to. The new Bishop must specifically agree and act to take on the rights and responsibilities of legitimate superior to the diocesan hermit and do so on behalf of his successors as well. He must agree to receive vows in his hands --- or the canonical or functional equivalent.) If a Bishop refused to do so and the hermit moved to this diocese anyway, the new Bishop would indeed be her Bishop, but he would not be her legitimate superior and she would not be a diocesan hermit (her vows would cease to be binding due to the substantial change in circumstances and could be formally dispensed by her former diocese). The two relationships (pastor vs legitimate superior) obviously differ in significant ways.
To summarize then, the act of making vows in the hands of her Bishop binds both the hermit and the Church as a whole in a constellation of mutual rights and obligations which differ from those which obtain at Baptism. Together, serving one another in a legitimate (that is, legal) relationship, they free the hermit to live the life she is called to and help ensure the eremitical life itself continues to be a vital and integral part of the church's patrimony.
