as I understand some of them.
E-Mary was a sinner like all humans, her body decomposed like all others and she cannot intercede for people just like no other people who are dead can either. C-Sinless, her body never decomposed, and she can intercede for people.
E-Lord's supper is a sacrement but symbolic. C-wine and crackers become actual blood and body.
E- man has direct access to God and needs, and indeed cannot have, anything between man and God. C-Pope, various appointed saints, Mary, etc. can intercede for man with God and may even be necessary.
E- when man dies he goes to Heaven or hell. C- when man dies, he goes to Heaven, hell or purgatory and can be prayed or bought out of purgatory.
E- The Bible is for man's direct edification and inspired by God. C-need Pope's or priests help to explain Bible.
E- only God can forgive sin and then only when man repents and asks for God's forgiveness. C- Pope and priests can forgive sins also.
There are others too. Am I correct?
