Church and other such institutes, where strict celibacy is adopted, cannot be free of erratic sexual behavior. Sex is a natural things but religions made it a sin. They do not try to make people morally strong but they tried to suppress their sexual desire by artificial means.
In Kerala India, a nun accused a priest of raping her but no action has been taken from either the government, or the church. In fact, church is trying to brush the matter under the carpet. It is saying that this was done to malign the image of the church. Is this not the height of shamelessness?
