It's at the discretion of your priest, of course, but that seems rushed to me. Such a short period of preparation means that your priest has a high level of confidence in your readiness.
I have been a catechumen for about six months and am being received into the Antiochian Orthodox Church by chrismation next Sunday. I personally would not have wanted to be received into the Church any sooner than this -- these six months have been a good time to talk with my priest, to read books and reflect on the new direction that I am taking in my life, and to attend services and experience a substantial portion of the liturgical year. As a convert from Protestantism, this is a big step for me and not one that I want to take hastily.
On the other hand, I don't think that the period of being a catechumen should last more than a year unless there's a good reason. Orthodoxy is an evangelical faith -- we want to bring people into the Church and not discourage them by setting up stumbling blocks.
Besides thinking about what's good for the individual, we have to think about what's good for the Church. Bringing people into Orthodoxy who haven't had time to make a seasoned decision is bad for the Church (no offense, just generalizing here). That is likely to produce skin-deep converts who may cause problems in the Church because of their lack of Orthodox understanding, or they may have a low commitment level and leave as easily as they came in. At the same time, though, overly long catechumenates are also bad for the Church. The Church then begins to look like a very exclusive club, and inquirers may walk away when they meet somebody who has been a catechumen for two years with no end in sight!
I like the well-worn analogy of marriage. Both becoming Orthodox and getting married are intended to be lifetime decisions. You want to make a mature decision and not get caught up in the excitement of the moment, only to have regrets later. Being a catechumen is like being formally engaged -- it's helpful because you are stating your intention to make a commitment up front but are then giving it some time. It's not so much about the length of the formal period of being a catechumen (or being engaged). It's about really understanding what you're getting yourself into and not hurrying into things.
I was baptised in the Catholic Church but converted last year to Orthodoxy. The conversion itself was extremely fast and simple, I told the priest that I want to convert, fasted for a week and then had a Chrismation along with receiving Communion. All in less than two weeks. However, I recently learned about catechumens which is something I never went through. Is this normal and proper? I am just surprised to see people taking two years to convert, what do these things depend on?
