Thanks for your questions. I have written about this several times quite recently and am not sure what else to say about the matter. I would ask you to check out the following posts and others under the labels ecclesial vocations or ecclesiality as well as canonical vs non-canonical vocations, etc: Follow-up, Who Can Live c 603? and Once Again on "Illegal" Hermits. In these posts and many others, I have focused on the distinction between ecclesial vocations and those that are not, why it is important for the Church herself to extend God's consecration to the hermit with an ecclesial vocation, what it means to belong to a stable state of life, and several other things including ministry of authority, sound spirituality, competent discernment and formation, etc. The only other dimensions I have not dealt with are that of potential self- deception and the problem of being unprepared for an authentic hermit life and perhaps incapable of living it well.
To claim one is consecrated by God in a private act may or may not be true or accurate. One may or may not have gotten it right and there is no way for the Church to verify it. (One can certainly examine the rite used and the intentions of the minister if there is paperwork to try and determine the reason for the rite. If it involved private vows, then there would be no consecration.) In any case, in the Roman Catholic Church, admission to Divine consecration requires initiation into a stable state of life where this gift of God can be verified, protected, nurtured, and governed. Because such a gift is NEVER for the individual alone, and because the vocation belongs to the Church before it belongs to the individual, the Church establishes such vocations in law and provides for the structural elements I spoke of recently that will allow them to be lived as the Church understands they need to be lived out. The discernment of such vocations is mutual, involving both the individual and the church because they are ecclesial vocations. The Church is responsible for selecting and professing those with such vocations and God works through the Church via a second consecration beyond baptismal consecration. No one can validly claim God consecrated them in the RCC unless this Divine consecration is mediated to the individual through and in the hands of the diocesan bishop or, in communal religious vocations, in the hands of other legitimate superiors!If someone insists otherwise, they are at least mistaken and perhaps even deluded in this matter. There is simply no such thing as private consecration in the Roman Catholic Church. Yes, one may make private vows. Many people do! But this is not the same as consecration. Neither are private vows an act of profession. Profession is an act that includes one's dedication of oneself in avowal and the taking on of the canonical rights and obligations of a new state of life. In other words, it is a broader act than just the making of vows. Meanwhile, consecration is part of the entire rite of perpetual profession where the individual dedicates herself to God with a perpetual avowal, and God consecrates that individual as they take on the rights and obligations of this new state for the whole of their lives.
As I noted above, Divine consecration that is part of initiating one into the consecrated state of life is a gift of God entrusted to the Church and only then to the individual. Also, please note that this is not a matter of putting Divine consecration up against Episcopal consecration. These two belong together or there is no consecration. It is not that bishops consecrate if by that we mean they do this for some while God consecrates others! No!! God consecrates hermits, and God does so in the hands of his bishops (or other legitimate superiors when we are speaking of hermits in congregations). The Bishop is not a "stand-in" for God, as I heard it put recently. Rather, God works in and through the Church specifically in the person of the bishop by empowering him to mediate God's consecration of the individual.Self-deception aside (somewhat), the greatest difficulty of asserting God has consecrated one privately, is that one may be completely unprepared for living out an eremitical vocation. They may not understand it and critically, they may not be able to negotiate the tension between the modern world and eremitical life that allows the hermit to be a gift to the contemporary Church and world. As I have said here many times, it takes time for both the individual and the Church to discern and form the vocations of solitary hermits. It takes probationary living out of the calling under the supervision of the Church while working with a competent spiritual director and continuing to discern. It takes study, collaboration, and deliberation; above all, it takes humility and docility.
One must be able to be taught and consider that ultimately one really might have gotten things wrong. When someone continues to insist, "God consecrated me," apart from canon law, apart from a bishop's permission and entrusting of the vocation to one, or according to established Church structures and rites, and particularly when they do so while denigrating the need for these ecclesial elements and context or while banging on and on about how they are the ones to show dioceses and other hermits the true way hermit life is to be lived, they are unlikely to be showing either humility or docility. This is not the same as saying "I am convinced God is calling me to this vocation; I know it" and persisting in that even when a diocese is unwilling to profess one under this canon for the time being. One may be called to persevere in good conscience in such a situation and do this with an openness to be taught about why dioceses make the decisions they do. In the meantime, perhaps one will also learn about ecclesial vocations and what one is proposing to take on and for whose sake!! Until and unless one does this, one is more an isolated person than a hermit. And that argues against one's having been consecrated by God (or called to this), not for it!
