I appreciate your invitation to tour the Catechism, but what is so strange is that what Catholics believe their Church believes varies from one poster to another. The same thing Catholics accuse Protestants of. This is why there is a necessity of having a final authority on beliefs and teachings. For you it is the Catechism, for us it is the Bible. I don't see how there is ever going to be a bridge built over that gulf.
We are not replacements for Israel, we are the receivers of the New Covenant.
"For finding fault with them, he saith, Behold, the days come, saith the Lord, when I will make a NEW COVENANT WITH THE HOUSE OF ISRAEL AND WITH THE HOUSE OF JUDAH. Not according to the covenant that I made with their fathers in the day when I took them by the hand to lead them out of the land of Egypt; because they continued not in m covenant, and I regarded them not, saith the Lord. For this is the COVENANT THAT I WILL MAKE WITH THE HOUSE OF ISRAEL after those days, saith the Lord, I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people." (Heb. 8:8-10).
Not really a variation - it is only that they don't have a full understanding - I don't claim infallibility and neither should anyone else outside of the Magisterium. But you guys who are Bible Believers (tm) don't actually believe in the Bible - we have ample proof. You guys believe in coupon clippings and snippets put together in random order. Witness the repeated claims that the Gospels are not for Christians, or that the snippets of Paul supersede the words of Christ. As I have offered to you offline, I would be more than willing to serve as Vergil to your Dante through Christianity. I would extend that offer to many, although not to all. There are some that turn my stomach in their evil.
