The statement in Romans 3 is a generalization, -- read the context. What it says is that as a race, man without Christ is a murderous criminal. But Mary is not without Christ and other righteous people are described in the Bible to whom Romans 3 clearly would not apply.
If one person could be sinless, why would we need a Saviour?
So that we, too, be free from sin.
NO ONE could go to Heaven without the Blood sacrifice of a perfect "Lamb"
Very true. The Catholic Church teaches exactly that.
Mary ... being raptured into heaven without death is made up myth
The Church does not teach "without death". But the scripture says she is in heaven (Apoc 12), and with all the interest in the relics of saints, no relic of the Blessed Virgin was ever found.
The same veneration you give Mary are due unknown people in China and Africa that are murdered everyday for the cause of Christ.
Yes. We should venerate all the saints and martyrs of the Church.
Many things you believe are not to the point of losing your salvation, but error is very dangerous. The Bible doesn't say what you might think or believe other than Jesus was born of a virgin, He lived a perfect life, and His sacrifice on the cross was a substitution for my punishment so I could be received in Heaven. All the other stuff is good to know info, but it won't keep you out of Heaven. You faith is what saves you, not works, not your denomination, etc. What you teach IS dangerous however. It could lead to things like worship of the wrong deity, conversion to the "Mother Earth" worship, and so on. The verse that Catholics base their whole church dogma on is even wrong. When Jesus asked Peter "Who do you say that I am?" He answered "The Christ". Jesus said that only the Father in Heaven could have revealed that to him. You guys get all hung up on Peter, but you miss the meaning of the statement. Jesus was saying that He built His church on the principle that ONLY GOD can reveal Jesus to you as the Christ and His church would be built on that principle. A person cannot know that Jesus is Christ unless the Holy Spirit reveals it to him/her. Jesus said that the Father gives Him His saints. It had NOTHING to do with Peter. Peter was no more powerful than Paul or John, or anybody after this statement was made. There is no mention of a pope, cardinals, or any of the other governmental stations made by Catholics. All the stuff about nuns and celibacy and fish on Friday and purgatory and indulgence's and on and on is just made up stuff. The killer for me was when they said my children were bastards if they weren't in the Catholic church. Sounds like Bin Laden and his ilk to me.
I have given up on evo threads, and should give up here because it is very difficult to de program Catholics without being in person with our Bibles and talking face to face. I do appreciate your tone, however, because most Catholics would have threatened me or called me names by now. If Christians can't discuss the Bible then we aren't much better than Muslims.
