It is normal for one’s depart from a religious life (or a seminary) to be given a recommendation letter by his/her superior or bishop. What is written in the recommendation letter can give the answer easily as to whether this an individual can be received again by this very community or any other.
However, it may happen also that another superior or bishop can be convinced to take him/her regardless what is written, or after considering a number of years since the recommendation, and/or by considering the satisfaction of the testimony of his/her life after departing (“suspension”) from the previous community. Nevertheless it is simply considered to be the superior’s action “at his/her own risk.”
