Richard Bennett, former Roman Catholic priest, has put together an excellent chart that compares what the Word of God says and what the Catholic church teaches. You will need Adobe Reader to view it.
Just because a church has been around for a long time does not make it right. We must be able to compare its teachings with God’s Word. There must be a measuring stick of some kind that tells us whether or not we are being deceived. We cannot act like an ostrich and put our heads in the sand for one day we will all stand before God to give an account.
~Romans 14:12 So then every one of us shall give account of himself to God.
