In my understanding, the reference to "stricter separation from the world" in canon 603 is an intensification of c 607.3. That section of canon 607 reads: "The public witness to be rendered by religious to Christ and to the Church entails a separation from the world proper to the character and purpose of each institute." [Emphasis added] Generally speaking hermits living under c 603 are called and obliged to live a separation which is stricter than that of other religious. Hermit's vows (or other sacred bonds) will qualify their relationship with the world in terms of wealth, relationships, and power (poverty, chastity, and obedience) but will, in conjunction with their Rule of life and the other requirements of canon 603, do so even more strictly than those of other religious. In particular, the hermit's ministry or apostolate will be very different because in the main it is a matter of being sent into the hermitage in the ministry of prayer and not out in active ministry. I don't think it means more strictly than cloistered religious, however, because hermits are self-supporting and responsible for interfacing with her local, parish, and diocesan communities --- and even with the more extended support community I mentioned in a previous post.
I don't think the requirement regarding stricter separation from the world is a form of judgmentalism but it does require significant discernment on what, when, and how one will give one's heart to things -- first to God and then to all that is precious to God. Stricter separation from "the world" is meant to allow one to love and/or be loved by God in a way which leads to conversion and sanctification -- that is to authentic humanity -- and in light of that, to love all that God loves in a similar way.As noted in earlier posts, The Handbook on Canons 573-746, notes that "the world" refers to "that which is not redeemed or open to the salvific action of Christ". I have added other dimensions to this definition: 'anything which promises fulfillment apart from Christ," for instance. Thomas Merton warns against hypostasizing "the world" and sees it in terms of illusion which should be unmasked; it is that which has become a lie and which needs to be seen for what it is.** (see below) We do that when we see all of reality with the eyes of God, and that means seeing all of reality with the eyes of love, just as I noted in my homily for the Solemnity of Ascension. What it does not mean is God's good creation generally. For that reason, the hermit does not reject the world outside the hermitage, nor even that which is antithetical to Christ. Instead her silence and solitude (i.e., her life with and in God) allows her to see things as they are and to help love them into wholeness. Stricter separation from the world is done for the sake of the hermit's capacity to see clearly and to love truly and deeply. This includes learning to see herself clearly and learning to love herself rightly and profoundly.
So again, no, I don't think stricter separation from the world represents a form of judgmentalism any more than a physician's diagnosis in order to treat a disorder represents a form of judgmentalism. For the hermit, stricter separation from the world, means disentangling ourselves from all kinds of forms of enmeshment so we may see properly and love profoundly into wholeness. This is what I meant when I said it required significant discernment on what, how, and when we would give our hearts to things. I hope this is clear. So much spiritual writing treats "the world" as anything outside the hermitage, convent, or monastery doors or walls. But this is just careless and dangerous thinking. It neglects the very real dimensions of the human heart which are worldly and on which one cannot simply shut the hermitage door; it also neglects the Great Commandment of love and the profound relationship a hermit (for instance) must have with the world around the hermitage, especially in the silence of solitude -- as paradoxical as that sounds.I agree with you that Jesus would condemn many writings that speak of "the world" as though it is a distinct objective thing outside a religious house. Especially I agree that Jesus would condemn any way of seeing God's good creation which ignores the victory of the cross over sin and death and over the powers and principalities of this world. We are challenged every day not to ignore "the world" but to see it clearly, to transform it with love, and thereby to eventually win its allegiance to Christ -- even if that allegiance is anonymous. Love provides the kind of unmasking which humbles without humiliating; it raises reality to its true dignity, and it allows the deep meaning possessed by reality to come through without idolizing this world or dimensions of it. It provides the lens through which we can see things truly and value them rightly. I think Jesus saw reality in this way and we who profess that we are in and of him, must be able to demonstrate that we have the capacity to see reality in the same way.
Hermits separate ourselves more strictly from the larger world in order to cultivate this way of seeing, this way of loving. We do it so that we can be remade into a dimension of the heart of the Church; where others who share in the love of God in Christ are meant to be Jesus' hands and feet, hermits stand hidden and yet present as a representation of Jesus' own sacred heart. Once we think of ourselves in this way, stricter separation from the world will never again mean a sterile, much less judgmental, disengagement from the world. Instead it will be a new and paradoxical way of being engaged so the world may truly be and become all God calls it to be. Stricter separation from "the world" is about love for the world of God's great and creative goodness; it is not about "contemptus mundi" except to the degree we reject the ways the world itself has been falsified by human idolatry. It is this falsification (and the distorted human heart that created it) that must be unmasked, and this, it seems to me (and to Thomas Merton, I think) is the work of the hermit and her hermitage.** And for anyone who has seriously entered into the medieval Christian. . . conception of contemptus mundi [hatred for or of the world],. . .it will be evident that this means not the rejection of a reality, but the unmasking of an illusion. The world as pure object is not there. it is not a reality outside us for which we exist. . . It is only in assuming full responsibility for our world, for our lives, and for ourselves that we can be said to live really for God." Thomas Merton, Contemplation in a World of Action.
