The Catechism of the Catholic Church specifies in numeral 2354 that “pornography consists of removing sexual acts, real or simulated, from the intimacy of the protagonists, to deliberately exhibit them before third parties. “It offends chastity because it distorts the purpose of the sexual act.”
Pornography, the Catechism continues, also “seriously violates the dignity of those who dedicate themselves to it (actors, merchants, the public), since each one becomes an object of rudimentary pleasure and illicit gain for another. It introduces some and others into the illusion of a fictitious world.”
“It is a serious offense. Civil authorities must prevent the production and distribution of pornographic material,” concludes section 2354.
