By that definition, it would be best to put candidacy right before diaconate then.
If Candidacy is like engagement, then seminary studies is like courtship. You don’t do the courtship after the engagement, that’s just silly. During the Seminary up to Diaconate there is always the possibility that you are not called to be a priest. It would be imprudent for a diocese to stop discernment so early in the process when there are many years for the person to learn and discern themselves and for the diocese to discern (through the formation team) that this person is called to priesthood and would make a good pastor (a good shepherd).
There doesn’t really need to be a shift, in my opinion. Most guys I know in the seminary are discerning God’s call for them but believe (in at least a small way) that this is where God is leading them. We don’t generally get the guys who aren’t sure buy just are “trying it out”. All of the guys, at the very least, want to be a priest in some way (one of the questions in my vocation interview was “Why do you want to be a priest”).
There is no inherent contradiction for a man wanting to be a priest but still being open to the Will of God. There needs to be something more to lead you to the Seminary besides “spiritual searching”.
Well, as it is said, all analogies limp.
According to the PPF, prior to entering major seminary (Theology), men will have spent 2-4 years in seminary formation (Pre-Theology or Minor Seminary).* Include in this both the application process (which varies) and the discernment necessary before beginning the application process and seminarians have spent several years seriously considering the priesthood. Analogy-wise, this would, to me, seem to be the courtship period.
Interestingly enough, the PPF considers the
decision to apply for seminary the first step of vocational discernment. This is followed by the next step, which is the actual application process to a diocese. If accepted, the seminarian then applies to a seminary. Then, the seminarian moves into pre-theology or minor seminary, which is preparation for theology. When entering theology, seminarians have already undergone at least three major steps in discernment over a period of several years, as well as rigorous self/peer/faculty evaluations.
At this point, there should be a shift in discernment. Note, a
shift in discernment. Discernment never simply stops. The seminarian should begin a change in himself, in his prayer, asking no longer “Is this where God is calling me?” but “This might be where God is calling me. How can I live out this way of life?” It is also a time for the Church to respond to the seminarian’s discernment up to this point, providing a more formal commitment to the seminarian and re-inforcing their support of him. As with an engagement, the seminarian and the Church will still have time to discern God’s will and, if it be so, leave the seminary. But, at this point in discernment, there should be more of a certainty then when one entered seminary.
And, curlycool89, I agree that there is no inherent contradiction for a man wanting to be a priest but still being open to the Will of God. Admission to Candidacy does not stop one from being open to the Will of God. Instead, it is simply helping to start solidify what that will is. It is for these reasons I think that it should be (and, historically, has been) at an earlier point then most US seminaries allow for.
*If high school seminary is attended, that adds another 4 years of seminary formation.
PPF = Program for Priestly Formation. This is basically the USCCB guide on how a seminary is to be run.
