Since the Catholic Church no longer engages in slaughtering those of other faiths... more power to you!
I look forward to the day when the same can be said for many of the Muslim faith!
I think you have read some bad history. You need to find some unbiased accounts of the Inquisition and the Crusades.
All of us are sinners, even Popes. There have been very few bad Popes and the bad Popes never taught heresy. That is the point. The Church is Holy becuase it belongs to Christ. The Church is Holy because it’s teachings are Holy.
The Church is for sinners. We all need forgivenss and redemption.
Don’t reject Christ because of Judas!
