[[Dear Sister Laurel, I need you to clarify something for me. Are you saying that hiddenness is not an important value for the hermit? I think hermits make sacrifices so wouldn't remaining hidden be one of these especially when one is ill and needs medical care? Wouldn't a hermit accept the sacrifice of hiddenness and forego some kinds of contact with medical personnel? Why would it be different for someone who is privately vowed than it is for someone publicly professed?]]
Thanks for your questions. Hiddenness is a characteristic of eremitical life. It can be and often is an important value but in the eremitical life it is also a derivative one. Hermits do not make vows of hiddenness, for instance. Canon 603 does not even mention hiddenness much less make it normative. Instead solitary canonical hermits are bound to a life of "stricter separation from the world", "assiduous prayer", and "the silence of solitude" for the praise of God and the salvation of others. Hiddenness stems from these normative elements. It is derived from them and is a helpful description of a significant dimension of these elements; clearly the Catechism of the Catholic Church knew this. However, this also means it is not normative in a way which allows it to supersede more fundamental values and obligations -- the obligation to live well, to take care of one's health, to be sure one's eremitical life is a witness to the Gospel of Jesus Christ to others in ways which edify (build up), and any number of other obligations.
The "silence of solitude" has a fullness of meaning beyond mere silence and solitude; it points directly to the wholeness, integrity, stillness, and completeness of the life lived in and for God alone. Every human being is called to "the silence of solitude" as the goal of their lives even if they are not called to live in eremitical silence and solitude or witness to this specific wholeness and holiness with lives defined in terms of "the silence of solitude" per se. "separation from the world" is a value in and of itself because every human being is called to be separated from those things which promise fulfillment apart from God or which resist the God who comes to us in Christ. Most, however, are called to live this separation while living within the world of everyday affairs and concerns. Hermits live a stricter separation in a more intense and paradigmatic way; they do so to witness to the importance of "cleaving to God" in every person's life. But hiddenness is different. It may be a value and will be if it serves these other values, but it may also be a disvalue. Consider what hiddenness means if it is linked to fear, escapism, a lack of integrity, or hypocrisy and dishonesty.
My canonical eremitical life is an essentially hidden one marked by assiduous prayer, study, inner work, contemplation, recreation with God for the sake of balance, wholeness, and so forth. But the hiddenness is meaningful and of witness value only because and to the extent it serves and reflects these things --- only to the extent it serves the central elements of c 603 life outlined above. If I spent my days merely watching TV or sleeping, reading, and eating bon bons etc, if, that is, I lived in ways which actually gave the lie to my eremitical commitment, my life would also be hidden but the hiddenness would actually be a disvalue and it would be destructive and disedifying to the eremitical vocation and the Church who received my commitment and consecrated me. (Please note, I am not referring to days or parts of days when illness prevents my more usual eremitical life here. I am just trying to contrast what my eremitical life is meant to be vs something it is NOT meant to be and how both of these reflect hiddenness.) Thus, again, hermits do not make vows of hiddenness nor are they called to hiddenness except as a derivative or subordinate value which serves more primary values. To reject necessary medical care or refuse to build a necessary network of folks who can assist one in case of serious illness or other need in the name of "hiddenness" is wrongheaded and, I would argue, unwise and illegitimate.
Your questions about sacrifices fit in here. Yes, eremitical life is marked by sacrifices -- as is any life which is truly given to God in all things. But note that this means it is a moral life in which objective values are discerned, prioritized, and acted upon. Hiddenness of itself is not a value which can trump a commitment to fullness of life. Were I, as a canonical hermit, to decide to forego necessary medical and/or post-surgical care (especially after I had appropriately discerned the rightness of having the surgery in the first place!), my superiors (bishop, Director/delegate) would have every right (and obligation) to question my decision and to work with me to be sure my decision was well-founded and served not just myself but the eremitical vocation I live. In something serious like this they would need to agree with the quality or soundness of my discernment or they could even require me to accept the care my physicians have said is required for good post-op recovery.
Note well, that the question of elective surgery itself is something that requires discernment; assuring sufficient assistance for a good post-operative course would be part of that. I could not agree to elective surgery as the will of God in my life unless I also could affirm that the necessary post-operative care was something I could commit to in this way. If the surgery is not elective the necessary post-operative care is still undertaken as part of the necessary surgery itself. As you might guess, for most hermits the real sacrifice in any of this would be to accept the necessary medical care and assistance of others because we do love our physical solitude. And yet, in accepting assistance in this way the hermit witnesses to her solidarity with others even in the essential hiddenness of her life. She reminds every person that eremitical solitude (which, again, is very much more than just physical solitude) is actually a unique way of living community; she reminds us all that Love is the highest value of her life and that loving and being loved is the highest dynamic in every life --- but certainly in the life of a consecrated hermit living a solitary vocation affirming the sufficiency of God as Love-in-Act.
In light of all this the consecrated (publicly professed) hermit cannot make hiddenness an absolute value; even less can she put hiddenness above this most foundational witness -- especially when the Church will allow the mitigation of even physical solitude in order to accept appropriate care and assistance. Moreover, in a point I made in the last post, if a canonical hermit is allowed and even required to accept such mitigations, how much more so would this be true for a lay hermit whose commitment is a private one? I hope that to some degree at least this answers your question about the difference between publicly professed hermits and those with private commitments. If you feel it does not I would encourage you to read other articles on the differences between private vows and public profession, especially those dealing with the public rights, obligations and expectations which are part and parcel of any public commitment. And of course, if that is not sufficiently helpful to you, please get back to me with your questions.
