Hi there yourself! Thanks for the questions!! I appreciate your calling attention to words I use that may not be clear to readers, so thanks especially for that. Yes, you have it exactly right; coenobitical or cenobitical life refers to life in community, especially monastic life. It is the complement of the term eremitical which means a solitary desert dweller and refers to hermit life.
Stages of Religious Life (Coenobitical context):
Now, for the time frames and stages. I'll start with the stages. You have it essentially right. The stages of religious life are candidacy (postulancy: the word is rooted in the idea the person is seeking or asking to be received into the community and comes from the Latin postulare), novitiate, juniorate, and perpetually (or solemnly) professed -- depending upon the community or congregation. These stages refer to the gradual initiation of a person into life in an institute of consecrated life and especially to the various rights and obligations thereof -- including passive and active voice in determining the way the congregation will continue to live its charism and mission. So, for instance, a candidate is not yet a member of the community and has no rights in its regard, neither passive nor active. A novice has been received formally into the community but is a complete beginner or novice in her understanding of the congregation's charism, etc; she, therefore, has quite limited rights and obligations in regard to the life of the community.The next stage is the juniorate, the stage of those who are temporary professed (they are identified as Junior Sisters or Juniors); in this stage Sisters (or Brothers, of course) have passive voice in congregational matters and may attend general chapters, but they may not hold office or submit or vote on proposals, etc. The final stage in formation is entered with perpetual profession (and consecration). These religious (the "Perpetually Professed") also have what is referred to as "active voice" and contribute to and vote on the decisions facing the community; these Sisters are allowed to hold office in the Leadership Council. What I have stressed here and want you to see is the fact that these stages gradually initiate a person into the life, charism, and mission of the community and ready them for responsible places in the mission, governance, and continuation (or completion) of the congregation.
The time frames which are usual today are: postulancy (6 mos to 1 year); the postulancy (or candidacy) may be extended but not by more than six mos. Novitiate; 1-2 years. One of these years is considered a "canonical year" and is lived according to canon law's strictures. There will ordinarily be no participation in ministry, but time to learn about the vows, study re the congregation and the church, and introduction to prayer and all the forms of prayer necessary in the life being embraced. The novice may take graduate level classes in theology and church history, and there will be regular spiritual direction --- usually with an outside director. If there is a second novitiate year (i.e., a year besides the canonical year), there is usually some participation in the ministry of the congregation and education continues. Often the canonical year is the second year. It is called canonical because canon law requires one year given over to what I described above. Novitiate may also be extended by (I think) not more than six months. The juniorate (time of temporary profession) can extend to six years, but (at least in contemplative monasteries) cannot be less than five years from first profession to the day when one makes perpetual profession or leaves the community.Time Frames and Stages in Eremitical Life:
As you can see, a solitary hermit is not being initiated into common life or prepared for governance (leadership) and other active roles in a given congregation. Neither are they going to graduate school or (generally speaking) otherwise preparing for professional roles in ministry. (Some may take part in a program of formation for spiritual directors, for instance.) The stages outlined above simply don't fit as well or make the same kind of sense in the formation of solitary eremitical life. This is especially true of novitiate, I think. One may be finding ways to support oneself as a hermit, but in that case, it could be argued the person may not be a hermit living c 603 life yet and a mutual discernment process should be postponed until that arrangement is established.
The point is that in terms of canon 603, one is either living and living more deeply into this form of eremitical life or one is not; there is really no other option. Time frames are far less meaningful here and distinct stages like candidacy and novitiate are artificially established, externally imposed and relatively meaningless. Especially unhelpful and even destructive is the arbitrary application of the time frames appropriate for coenobitical life to solitary eremitical life. Remember that c 603 is written and meant to be used for solitary eremitical life, not semi-eremitical life or life in a laura/lavra using a single Rule and forming new members --- situations where externally imposed time frames may make more sense.With solitary eremitical life there are no easily distinguishable stages, no. When one turns up at the local chancery seeking to discern a canon 603 vocation, one must already be a hermit in some essential sense. If one is not already a hermit in some very real or essential sense and already lives the elements of the canon, approaching the diocese with such a petition is entirely premature. The period of mutual discernment with a diocese is meant to determine if a person is called to live an ecclesial vocation as a hermit, that is, is she called to live eremitical life in the consecrated state and in the name of the Church under c 603? Dioceses do not form hermits; neither do they oversee a hermit's formation although they may accompany her in her ongoing formation during the period of mutual discernment and assist her in meeting the requirements that she be ready for vows of the Evangelical Counsels, as well as that she write her own Rule of Life.
Time frames in such cases are entirely individual and, in the process I have outlined, are better keyed to the hermit's various attempts at writing as liveable Rule which can and will eventually bind her in law. The diocesan discernment team adopting such a process would be able to use the various versions of Rule the hermit writes to assist her in understanding where her own eremitical formation needs attention and perhaps where or how the diocese can connect her with various resources she can benefit from. Additionally, the team can use the various versions of the Rule the hermit writes along with conversations with the hermit to gauge readiness for temporary and perpetual professions under c 603. Since there are other forms of eremitical life open to the hermit including lay (that is, non-canonical) hermit life as a solitary hermit, eremitical life lived in a lavra or laura, and semi-eremitical life, only a calling to solitary eremitical life under c 603 is the focus of the diocesan discernment team.
(I should point out that early on chancery personnel were sometimes reported to tell a person that they should "just go live in solitude, that this was all they needed". I disagreed with this advice fairly emphatically 15 or 16 years ago. However, my position may have changed somewhat or become more nuanced at this point. It depends on whether these dioceses asked the persons to return after some time lived this way for another conversation if the person felt the need. If the dioceses meant, "Please go live in solitude until you are made a hermit in that way with the assistance of the Holy Spirit and return to us if you believe you have an eremitical vocation as a solitary consecrated hermit under c 603; at that point we will discuss undertaking a mutual discernment process together", I believe those dioceses were on the right track.**Please note, the laura/lavra referred to above envisions something like the Hermits of Bethlehem which has become more community than a colony of solitary hermits, each with their own self-written Rule. C 603 is meant for solitary hermits who must be able to support themselves and live their professions should a laura/lavra dissolve.
