We as baptized are the Body of Christ through the Catholic Church as founded by Jesus and protected by the Holy Spirit until the end of time.
I am with Jesus Christ and His Church with the Sacraments. We are all sinners, even the Pope and Cardinals. Many Catholics are saints and we should try to follow their example and the example of Jesus and the Blessed Mother. We need each other and we need to help all grow towards loving God and neighbor.
So you leave the Church because of a few individuals, look at what Jesus endured for your salvation, you can certainly endure His Church?
No one is capable of doing it alone without God, and his best help is in His church.
You don't realize this but you're equating Jesus and Mary to be on the same level.
