[[Dear Sister, Wouldn't it be possible for the Church to discover that the vocation of consecrated virgins living in the world has developed in a way which requires the kinds of things you say separate Religious from aspects or dimensions of the world? I understand your argument that this would mean the Church was wrong for 30 years, but vocations DO develop. Why couldn't a mitigated secularity (your words) be a development?]]
That's a good question and I am pretty sure it is precisely what the minority of CV's who desire the separating trappings of Religious life would argue. When I spoke of being free to experiment in my own vocation in order to discover the shape of eremitical life in the 21st Century I was referring to this question indirectly. You may remember that what I said there is that any experiments I might do would be limited by the nature of my vocation. For instance, I can't make it a secular vocation when part of the canon reads "stricter separation from the world" --- and so, defines this as even more intensely non-secular than other religious vocations. I can't do this when the liturgy by which I was professed stressed this separation at every point (official liturgy is normative as law is normative). Once my own vocation becomes secular it ceases being eremitical.
There is no calling it secular in the "weak sense" because I don't live on monastery property or out in the boonies, or in a literal desert for instance. It is eremitical because it is defined in terms of the central elements of canon 603 and the Rite of Profession we used, or it is not eremitical at all. Further, these elements are always the ones which guide my implementation of various practices; thus, if I am called on to do some limited ministry at the parish I have to be sure my life is still clearly eremitical in terms of stricter separation, assiduous prayer and penance, and the silence of solitude. I cannot begin to define my life as "less eremitical" or eremitical in the weak sense, or even as "more ministerial" --- as good as any of those things are generally. I am committed to keeping its essential nature or I will lose it altogether.

While I have referred to canon law history, the theology of consecrated and religious life, Christology, ecclesiology, liturgy, and a few other things in various posts on this, my basic concern and argument is pastoral. The bottom line for me is that unless this is a thoroughly secular vocation (consecrated life though it is) it does not make sense; unless it is truly secular it will remain a somewhat half-baked, less than radical vocation (neither secular nor religious), and will be incomprehensible and inspiring to neither those living secular lives nor to those living as Religious.
Only if it is a truly secular vocation is it truly charismatic since charisms come from the interaction of the world's need and the influence of the Holy Spirit; only then will it speak relevantly and prophetically to a world-at-large which is called to live the life of the Kingdom in the state of secularity. (I firmly believe this world does NOT truly need yet another vocation which suggests secularity is NOT a call to a radical, exhaustive holiness!) I simply don't believe turning the vocation into a quasi-religious vocation will inspire most people to live an eschatological or sacramental secularity. While my own vocation can summon people to build silence, solitude, and prayer into their lives to a greater degree, and while it can remind them that it is God alone who completes us and is sufficient for our needs, there is also the danger that I give the signal one must leave the world to be a person of prayer, silence, or genuine solitude. I may, unfortunately, give the mistaken signal that one needs vows or special garb or legitimate superiors, to be called to or become holy. And so forth.

One final point. The ancient vocation to consecrated virginity went through a development which saw it used more and more exclusively for women entirely separated from "the world" and cloistered in monasteries and convents. This is now seen as something which turned the nature of the vocation on its head. (cf, Holland, Sharon, "Consecrated Virgins for Today's Church") Eventually, even the remaining secular expression of the vocation was lost (around 1139). It is the case that this loss corresponded to a time of decreased esteem for the secular and the association of the call to holiness with religious and priestly life alone. This development contributed to the hardening of divisions between sacred and profane, religious and secular, which was destructive of dimensions of the spiritual life of the Church and represented a kind of class-ism which is antithetical to the Gospel of Jesus Christ. Vatican II worked mightily to move past this in what she taught and the revival of the secular consecrated virgin vocation developed as a piece of this. I would therefore be chary of any suggestions that CV's wishing to recapitulate this original development from secular to cloistered in some way is a good thing. Moving away from the thoroughgoing and sacred secularity of the vocation seems to me to be doing just that.
