ALL religions can be perverted because they were devised/created by Men and not always as a product of the same Divine Inspiration as the Apostles were affected by.
Being made by Men, no matter how noble the intentions, I hold that religion in itself is sinful as it imposes its own form of The Law on the adherents despite the fact that trying to follow the Law is clearly being in a state of Fallen from Grace.
That said, the Catholic religion has probably done more to save souls than any other Christian religion (despite the long-term Latin Masses which left many of us in the dark - we knew the proper responses during Mass, but had no idea of what the priest or we ourselves were actually saying. I choose to be non-denominational because the Bible is the message and the New Covenant and Christs Love is the meat of the message - no thrills, no frills, just the Good News of Salvation and being justified by His Love vs. having to follow a bunch of Pharisee-type rituals which make one feel good about oneself, but serve no true purpose. No matter the topic of the day, my pastor always insures that Jesus is up front and center and His Love of us and our love of Him is what it's all about.
Hallelujah! Praise God. I'm blessed to attend a church where my pastor does the same.
