Nothing will truly change until the Church comes into the 21st century with its' teachings on human sexuality. The basic message I received growing up in the Catholic Church and attending Catholic schools was that sex equals sin. Masturbation was  a sin. Sex before marriage was a sin. Homosexuality was a sin. Extra marital affairs was a sin. The only sexual act that was not a sin was sex between a man and a woman united in holy Matrimony. And even in that case, a child born was born with "original" sin. When the Hierarchy saw that many of its' priests were engaged in sexual activity with children how did they see it. Of course, they saw it as sin. Nothing has really changed in the Churches' teaching in the last one hundred years regarding sexuality. If you molest a child, you simply go to confession and have your sins forgiven and go out and sin again.
