You should never leave the Church because of the errors made by humans. The Church Herself is Divine. But the people in it not so much. The Catholic Church makes headlines, but what about the public school system that is infested with sex abusers also?
When the news broke about the sex abuse last summer the archdiocese asked the government “will you also look into the sex abusers in the public school system?” The government said “no, that’s not in our interests.” Talk about hypocrisy huh?
You can’t excuse what has been happening in the Holy Mother Church. But when things are bad with the clergy, it is often the most devout lay people who stand firm and hold down the Faith. Eventually the clergy will get the message and clam up.
When we go to Mass, we go to receive Jesus in the Blessed Sacrament, no other Church has that! Also, we should be in the Church for Jesus Christ, and nothing else!
If you must, then do not give a single more dime of your money to your diocese until they get it together. Maybe also write a strongly worded letter to your bishop about what is happening and explain your stance. But by all means, if you support your parish, continue to tithe there to help keep it going.
“Don’t leave the Church, be the Church.”
To quote Saint Peter when everyone walked away: “But Lord, to whom where will we go?” And where else can you go, except to Jesus and to the Church He established.
Remember Our Lord promised the gates of hell shall not prevail against the Church. The Church has dealt with its adversities over the centuries, but the Church has always pulled through and stood the test of time! That alone should tell you the Catholic Church Herself is Divine.
