(e) Dancing may be a perfectly innocent amusement and it may be a dangerous occasion of sin. No general rule, therefore, can be given as to when dancing must be avoided. Much depends upon the company who join in the dance, upon the way of dancing, and upon the subjective disposition of the dancers. If there be nothing objectionable in any of these respects, there is no reason why a young man or a young woman should not be allowed to dance with due caution. If there be ground for objection, and especially if sin has already been frequently committed in similar circumstances, there is an obligation to abstain, unless the occasion of sin is necessary and can be made remote by taking proper precautions. If sin only follows occasionally, there will be no strict obligation to abstain from dancing, provided due precautions be taken in future.
(f) The question of theatre-going is settled on similar grounds. There are all sorts of theatres and all sorts of plays represented in them, and all sorts of actors and actresses. To go and listen to a bad and suggestive play arouses the passions, leads to sin, and encourages evil in many ways. It will, then, as a rule, be grievously sinful to go to the theatre to see such a play. The confessor will usually be able to judge best whether in any particular case it is lawful to go to the theatre by asking whether in the past it has frequently led to sin. If it has done so, it is a proximate occasion of sin, and must be avoided as far as possible. In other cases, unless the play or the theatre is known to be bad, there will be no strict obligation to refrain from going.
