By the way, you left out friars. These go between monks and active religious. They live the monastic life outside of the enclosure.
The Church does rank these ways of life in this verticle order. However, she does not say that one leads to the other. On the contrary, Canon Law is very clear that these vocations while they can overlap, they are not linked. Each is very unique and each is its own path. One never leads to the other. One can have combinations. For example: a consecrated virgin can be a nun, a sister, a hermit of a lay woman. The only thing that she cannot be is a wife. A woman called to be a consecrated virgin, can also be called to be a consecrated religious.
Let’s look at men. A man who is called to be a hermit, monk, friar or active religious can simultaneously be called to be a deacon, priest or bishop. He may even be a father, which is a distinct vocation from the consecrated life. What a man can never be is a consecrated virgin, even if he is a virgin. That call is only for women, just as the call to the sacrament of Holy Orders is only for man.
Having said that, among the religious there are also differences. Some religious belong to religious orders and some belong to congregations. Monks, nuns and friars always belong to religious orders. Religious orders always make solemn vows. The only other persons who make solemn vows are couples. The marriage vows are solemn vows.
Sisters and active never belong to religious orders and never make solemn vows. They belong to congregations and make simple vows. This means that their form of religious life does not have the same binding commitment as that of monks, nuns and friars. It also means that the Church does not grant them the same graces when they make vows and indulgences. There is a plenary indulgence attached to solemn vows, but not to simple vows. Only those who join a religious order can make solemn vows, not those who join a congregation. Married people make solemn vows. They too have special graces and indulgences.
However, even though married people make solemn vows, the Church still places the person who is a consecrated celibate in a higher state than the married or single person. This does not mean that the person who is a consecrated celibate is a holier person. The state in life is holier, not the person.
I can be on a higher run on a ladder, may appear taller because of it, but in fact I can actually be shorter than the person on the lower rung. Just because I’m part of a higher state in life, does not mean that I’m holier than a person in a lower state in life. Personal holiness and the holiness of the state in life are not the same thing. Each person must seek his holiness in his or her state in life.
The issue here is that many lay people take issue with this ranking. To those of us who are religious, this seems very strange. I’ll explain why. An active religous who belongs to a congregation does not take exception to being on a lower rung than a monk or a nun. It is an accepted fact and no one gives it a second thought.
A friar, who actually spans both the monastic life and the apostolic life, does not take exception to being in the middle rung between a monk and an active religious. To us, this is a fact and we’re perfectly happy with it. We know that we are not monks and that we were not called to be monks, because it is such a high state in life, that there is no way that we could achieve salvation in that state. Jesus in his mercy has called us to be friars, because we can rise to the challenge in this state in life, but not in monastic life. We’re not all made the same nor do we all receive the same graces. Chirst told us this in his parables.
So, to us religious, the question on this thread is one that we never discuss among ourselves, because it’s not important. What is important is to be in the state where Christ has called us and to live faithfully according to that state. Christ will never call us to a state in life where we will certainly fail. He will only call us to a state in life where we have a 100% chance of succeeding, if we are faithful. For us, that’s all that we need to know in order to be happy. I am where I can achieve sanctity.
