83 Now, with fatherly love and affection, Our heart turns anxiously and with deep sorrow to those unfortunate priests who always remain Our dearly beloved brothers and whose absence We keenly regret. We speak of those who, retaining the sacred character conferred by their priestly ordination, have nonetheless been sadly unfaithful to the obligations they accepted when ordained. Their sad state and its consequences to priests and to others move some to wonder if celibacy is not in some way responsible for such dramatic occurrences and for the scandals they inflict on God's People. In fact, the responsibility falls not on consecrated celibacy in itself but on a judgment of the fitness of the candidate of the priesthood which was not always adequate or prudent at the proper time, or else it falls on the way in which sacred ministers live their life of total consecration.
