One of the greatest problems of the autocephalous Catholic movement is the quality control of clergy. The movement as a whole typically attracts people for a variety of reasons. Some legitimately feel their beliefs do not fit with the Roman Catholic/Orthodox/Anglican churches, some wish to be married or in same-sex relationships, some are of another gender, and some could not have been ordained in another church.
I focus here on the last category. There are people who get ordained but have various psychological issues which should have prevented their ordination. I am not being hard on the movement as a whole, because we well know there are many more "mainstream" clergy who also should not have been ordained. The problem here with our movement is quality control. In the Roman Catholic church, for example, there is the requirement of excardination of clergy move dioceses. Generally, bishops will get permission from other bishops to accept a priest and will also receive a dossier of their suitability.
There is, unfortunately, no such process in the movement. It allows unsuitable clerics to move from jurisdiction to jurisdiction causing havoc on each one. Bishops often do not ask for letters of incardination because 1) they believe the story of the cleric about their supposed abusive bishop, 2) they really want to grow their church and it doesn't matter if the cleric is properly vetted, 3) they believe (perhaps like a forlorn lover) that they can "change" the cleric. I can honestly say that having a cleric who is psychologically unsuitable is a hardship that is absolutely not worth the time and effort. Like energetic vampires they draw out energy which could be used building up the Kingdom. Moreover, many of them should not be in positions of authority over unsuspecting laity.
I do believe that there is a legitimate issue with clergy who have unsuspectingly found themselves under problematic bishops. Because of the lack of general ordination standards persons can be elevated past their mental or psychological ability. This is a continuation of the discussion above, because problematic priests can become problematic bishops. However, I think it behooves us to at least reach out to a cleric's former bishop and hear their side of the story. Then, weigh the evidence and try to make some reasonable determination if the cleric is fit. If the bishop is abusive, combative, or downright crazy then maybe there is a reason the cleric left! References can also be helpful as can psychological evaluations. It takes a multitude of sources to determine if a person is suitable. And that, for bishops, is the most important part of your job. You have the power to ordain and license people who are entrusted with the souls of others. This is a tremendously frightening and sobering responsibility. It can't be taken lightly.
"The saying is sure: whoever aspires to the office of bishop desires a noble task. Now a bishop must be above reproach, married only once, temperate, sensible, respectable, hospitable, an apt teacher, not a drunkard, not violent but gentle, not quarrelsome, and not a lover of money. He must manage his own household well, keeping his children submissive and respectful in every way— for if someone does not know how to manage his own household, how can he take care of God’s church? He must not be a recent convert, or he may be puffed up with conceit and fall into the condemnation of the devil. Moreover, he must be well thought of by outsiders, so that he may not fall into disgrace and the snare of the devil." - 1. Tim. 3:1-13.
