The present paper is aimed at presenting selected psychological factors which may facilitate formation to the priesthood and those which may hinder seminary formation and the subsequent life of the priest. I separated two potential sources of hindrances: factors of a psychological nature and traits of personality. I proved that deficiencies in religious life and lack of support in the priestly community are the reason of high anxiety and depressive states in clergy. As for personality, I indicated emotional instability, introvertive tendencies, high selfreliance and autonomy, difficulties in accepting authority and inclination to dissimulation – as factors which hinder the fulfillment of vocation to the priesthood.
