I have three friends plus me who are trying to comprehend evil in the Church and/or people in the Church, people who proport to believe in what the Church teaches, what Christ teaches, but do not live that way in a consistent manner. When most people who believe and who do live their belief in the teaching of the Church and of Christ fall short we call that sin. When we see our own sin we reconcile with God. We have a grace filled Sacrament for that. Unfortunately not everyone does that. Some people in the Church, bishops, priests, employees are so wrapped up in evil, (whether they know it or not), that they are hard of heart and prideful. The pridefulness is manifested in either inaction in the face of the evil or in the obstinate embrace of that evil. Again, this is either knowing or unknowing.
Take for instance the clergy sexual abuse scandal. Countless priests and bishops seem to have disregarded not only the teachings of the Church but also the teachings of God. Then some priests, bishops and Church employees got in front of their congregations and the news media and lied about the entire situation. It is impossible for us to make any of them do the correct thing. The same goes for some congregants. We just have to pray for them and ourselves. (Never pray for some one else without praying for yourself also.)
When it is not about the sex scandal but some other abuse in a parish or in the Church the evil is still real and it seems to hurt individuals. There is even less caring then. Psychopaths and sociopaths are in every aspect of life, that is true in the Church too. Unfortunately that fact sometimes makes complaints about real evil being perpetrated fall on deaf ears.
Stay close to the Sacraments, pray for your enemies as well as your friends, and as difficult as it is sometimes, let God be God.
