Thanks for the question, but I don't know what that is. Seems to me someone asked something similar several years ago. I will need to look through some older posts to see if I can find that. If I can't locate it I will need to get more information from you. The truth, however, regarding the language of canonicity is pretty simple in the Catholic Church. A canon is a norm and when something is made canonical it means that thing, whether a collection of Scriptures, a form of life, a particular office, a set of requirements, etc., is normative according to the church's understanding of something; on the other hand, non-canonical means not normative according to the church's understanding of the thing. By virtue of baptism alone one can live an eremitical life in any way they believe is appropriate for them and feel called to do. However, one is not a Catholic Hermit because what one lives is a private matter and one doesn't live this life, nor is one called to do so, according to all of the norms (standards) governing canonical eremitical life. One does it instead by virtue of one's lay state and the freedom one has in Christ.
In this case, one dedicates him/herself to serve God in the eremitical life. S/he may make private vows of some sort, but they will not rise to the level of religious profession, nor will they be public or canonical. Because these kinds of commitments (public, canonical) are absent, and because the canonical rights and obligations (along with the expectations granted to the faithful generally in regard to this vocation) are similarly absent, we call this kind of eremitical life non-canonical. It does NOT mean illicit or illegal nor do I know anyone who considers this to be the case. Again, it is simply not normative of ecclesial eremitical life (i.e., it is not canonical) --- though it may well represent an excellent instance of eremitical life and one any hermit can learn from.
There are two other forms of eremitical life in the church and both involve public (canonical) profession and consecration by God mediated by the Church and are lived in the name of the Church. These are normative forms of eremitical life in the Church. Thus too, both are marked by legal or normative (canonical) rights and obligations that do not obtain in the first form of this life. Another way of saying this is to note that they are both canonical because they are forms of life marked by canonical rights and obligations beyond those that come with baptism. The first is solitary eremitical life (members of which could become a lavra on a temporary basis) and the other is semi-eremitical (a canonical community or institute of hermits), where one's profession is made within the context of the institute. In both of these one makes a profession which, by the way, means more than the making of vows (an act of dedication, by the way). Sandra Schneiders, IHM, makes it clear that profession is a broader act than the simple making of vows. First it is a public act in which the individual takes on the kinds of rights and obligations mentioned above and does so as an expression and realization of a gift of God which has been entrusted to the Church and can only be mediated to one by the Church.
Secondly, then, an act of profession is an ecclesial act where the church extends to the individual the right to make such a profession, affirms them as called to live this in the name of the church, and establishes with various structures and offices a context meant to assure the gift is well-lived and continues the tradition into which the individual has been professed as a living, fruitful stream of the Holy Spirit. This differs from a private avowal which ordinarily involves no one but the individual(s) making the vows. Someone may witness such vows, but no one receives them on behalf of the church, no additional public rights nor obligations are entrusted nor taken on, no change of state occurs (there is no additional consecration by God** so one remains in the baptized state alone), and so forth. With private or non-canonical eremitical vocations vows or other forms of dedication don't even need to be made (though foregoing these might be unwise). Still, the dedication may be informal or formal (though still entirely private) --- depending on what suits the individual hermit.For canonical hermits profession is made in two ways, first, for solitary hermits, under c 603. When this canon is used, the profession is made to God in the hands of the local ordinary. Because we are speaking about the public assumption and entrustment of the hermit with ecclesial rights and obligations, the rite of profession (involving both profession and commissioning) is mediated by the church. The second way is to admit an individual to membership in an institute of consecrated life living eremitical life. This is familiar to us as admission into religious life and all that constitutes that. Individuals make their professions to God in the hands of the Prior(ess), Abbot (Abbess), of the order, that is in the hands of the general superior. (In both of these forms or eremitical life, perpetual or solemn profession God's consecration of the hermit is also mediated with a solemn blessing of consecration given by the bishop. Similarly, visible symbols of the new state, rights, and obligations, dedication and commission) This mediation continues throughout the entirety of the hermit's life. Hence, it involves canonical structures, an approved Rule, legitimate superiors, ecclesial requirements, etc., to allow the church to ensure this gift of consecrated life contributes to the holiness of the church.
All of this is recognized by the church in her (still relatively) new Canon 603. Here she extends to the solitary hermit who petitions and is accepted by her diocese for profession and then consecration, the standing that had been extended to religious institutes throughout the centuries. Individual dioceses had done some similar things in the late middle ages, usually in order to introduce some structure, obligations, and responsibilities (i.e., norms) into the ranks of hermits traveling throughout the countryside, when bishops established statutes hermits had to commit to be allowed to represent themselves as hermits/anchorites or to preach and beg. But canon 603 goes further than these statutes for what c 603 does is establish the hermit in what was once called a state of perfection (now, the consecrated state) and allows a solitary hermit to be regarded as a religious despite not belonging to an institute of consecrated life. the Church did this not only to recognize the significance of the eremitical vocation, but to protect it and authentic vocations to it.Despite what sometimes seemed like hoards of solitary hermits (for instance, in Italy at the time of Romuald) and the number of institutes of hermits established over the centuries, very few of such institutes lived into the 20th Century and individual hermits became a rarity. Most well-known are the Camaldolese and the Carthusians, but there were also Carmelites, and some hermits within other institutes like the Trappists and Trappistines. Still, eremitical life was a rare and poorly understood vocation. After all, in the Western church, the eremitical life had almost died out. And of course, it was not so easy in the contemporary world to go off into the boonies and establish oneself as a hermit in the ways that were once possible. Moreover, our contemporary world often mistakes various other forms of life for the genuinely eremitical, including individualism, cocooning, misanthropy, agoraphobia, etc.
Within the church herself, contemplative life became rarer, genuine silence and solitude much harder to find, shifts in spirituality that themselves were healthy and the necessary emphasis on ministerial life threw shade on eremitical life. But monks and nuns continued to discover calls to greater solitude and silence than their life in community really allowed for. Eventually, in response, the church carved out a space for solitary hermits with c 603. The canonical requirements helped replace the institutes necessary for the Camaldolese and Carthusians, for instance. At the same time, no pre-existing forms of eremitical life were replaced by c 603. Instead, it created a new form of consecrated life. Those baptized and in the lay state could live eremitism in their lay state before c 603 and they still can! The same is true of clerics with their bishop's permission. Thus, no eremitical form of life, especially that made known by the desert Abbas and Ammas who embraced desert spirituality as laity, has been rendered illegal!!! To speak so is misleading and I consider it disedifying given the significance of non-canonical hermit vocations through the centuries.
