Different times and circumstances often mitigate,diminish and/or possibly eliminate certain sins from taking a hold in societies,institutions or nations. Nonetheless there have always been sinful behaviors among individuals that have gotten out of hand. The Church has not been immune to the effects of sin by its members;however,adherence to Christ's words,to Peter,to follow Him can produce a profound purity in those who choose Christ's way.
Clergy,who imitate Christ are incredible witnesses to Him. For that reason one of the goals of the enemy has always been to corrupt the clergy. One of the groups most dedicated to destroying the Body of Christ or the Catholic Church in the last century was communism.
One of the tactics that they used was to infiltrate the Church and place sympathizers or weak sisters in seminaries. Homosexuals were especially valuable because practicing homosexuals could be blackmailed and could also be used to create scandals which would place the Church in a position to be subject to public ridicule,disgust and opprobrium.
Efforts were made to recruit homosexuals,men who were able to go either way and also the weak sisters,who might be convinced,either to participate or be silent.
Bella Dodd who was vice chairman of the Communist Party USA (CPUSA) testified in the late forties that she had placed enough men in seminaries during the 30's to alter the entire Church by the seventies. (When she testified she had disavowed her party membership.)
So Dangus and Aquinas fan,you are both right but this last wave of homosexuality among the clergy (last century)probably started in earnest,shortly after our Lady's warning at Fatima in October of 1917,when she warned that the errors of Russia needed to be combated. It was very prophetic because shortly thereafter the Revolution came to Russia,the Tsar and his family were murdered and communism took hold which brought with it so many of the problems we are still facing.
With prayer and fasting this situation will resolve but we must always be on guard,to corrupt the clergy and get rid of the Pope are two lynch pins in the enemy's plan to destroy the Church. I always pray to God to help our priests and protect the Pope. Sorry this is so long but I wanted to put things into perspective,sometimes writing things out clears my head and reminds me of things I once saw clearly.
