a) Mistaken concept of sexuality. Difficulties are likely to arise once the priest gives in to the widely held view that human beings are biologically determined. The erroneous notion that the male is in a sense compelled to sexual activity by virtue of the very fact of being male, is becoming stronger and stronger. People even think that the sexual act ‘proves’ one’s virility; that without it, a man is in some way disabled, unrealized. Concepts of this sort, especially if repeated by medical authorities in the sexological field (as often happens) can easily be used to justify one’s own behaviour. From now on the individual, dominated by his own body, justifies himself by saying that ‘it is not possible’ to act otherwise.
** So it is extremely important for every priest to know how to maintain discipline over his thoughts and his imagination. For one can also sin alone, in thought: by looking at another person with desire, by treating that other person as an object, the sin of fornication is committed in the depths of the heart. If an attitude of this sort dominates the heart, it will also manifest itself outside. On the other hand, if we are clean within, no external situation can provoke somatic reactions against our will.Sexual excitement depends, in the first place, on the intentions with which we approach our neighbour, how we look at him or her and what we see there. The priest is obliged to see the very Christ in his neighbour; the aim of any encounter can only be to bring that person nearer to God.**
Lust tends to subordinate others to our will, subjugating them and humiliating them by treating them as objects. A father’s love, however, offers itself, asking nothing in return. But to attain to this, one must teach the body self-control. Chastity is, therefore, a constant effort to subject the body entirely to the aspirations of the soul. Each human being’s body is always subject to a spirit: either to the Holy Spirit, or to the spirit ‘of this world’.
