#11 - The Church didn't frog-march what they knew to be pedophile priests into the waiting arms of Police and State Prosecutors so that they could be tried for sexually molesting young boys and young women. Rather, the Church chose to hide these child molesting pedophile priests by moving them from parish to parish, without so much as thinking about the victims of these heinous crimes.
That's why. It's hard to assign legitimacy to a Church that fails to protect the youngest and most vulnerable, while protecting pedophile priests.
As for the ten problems listed, IMO every church whether Catholic, Protestant, Baptist, Lutheran, etc.. has those problems at one time or another. It's all in how that Church chooses to deal with the problems that keep them relevant (or not.) It's those Church's that change the message that ultimately end up losing. The message doesn't change, the message changes us.
One last comment: I was born, raised, reached communion and confirmation, and was married to my wife of 27 years in the Catholic Church. There are some incredibly good Priests and lay folks within the Church who IMO do God's work. It is a shame that #11 as I stated above continues to hang over the Church. That however is the Church's fault for not embracing the victims, and rather embracing the criminals within for so long.
I agree with you on #11. And I too am a practicing Catholic.
There are still, to this day, some who have never been brought to justice for what they did i.e. moving pedophiles/covering for them.
