Well, from where I sit, their symmetric claim about you is just as valid, which is to say not at all or at least not knowably so.
Saying that standards and beliefs have changed is suspect on it's face. ... God isn't into fads. God is consistent.
It's amazing that you think standards and beliefs have not changed over history and geography. Even within Christianity they have done so. And the tensions between the Old and New Testaments is plain - in the one it's smite thy neighbor and in the other love him as yourself.
On this judging thing, didn't Christ authorize his disciples to judge the sinfulness of men? My recollection is that the authority was unconstrained.
Oh well, that's enough for me. Feel free to have the last word.
No. I will repeat, there is much out there claiming to be Christianity which is in no way related other than on it's appearances. Let's use our brains for a second, shall we. If McDonalds were so successful that other outfits began emulating them and saying they were fast food joints, they would be fast food joints. What then if some of them started saying they were McDonalds and started doing all sort of things in the name of McDonalds which McDonalds didn't approve of.. Did McDonalds change - or did a bunch of disruptors acting in McDonalds' name present an image of change. Therein is the revealing of the lie and your misconception. Christianity has NOT changed. But a bunch of people with their own agendas have been working at Hijacking Christianity since it started - The new Testament tells us in the words of Paul that it was happening even then - and it hasn't stopped since then. Christianity hasn't changed a whit; but, the disruptors have had a field day making a mockery of it by their own actions. God is not mocked and all of them will have their day in court.. including Rome who has been at the head of them all for making a mockery of God's word.
Do others have different interpretations, sure. Nobody denies that. The pharisees had different interpretations too - they weren't Christians either. The judaizers were Christians who added the law and circumcision to the Gospel - just those two things.. They were Christians; but, because they added to the Gospel - the Christian message which now makes up our new testament - Paul said they are accursed. What does that make outfits who have added far more. It isn't rocket science; but because people treat God like Santa clause and religion like a social club, nobody really takes it seriously - afterall, it's just religion... You'll have your body for 70 years give or take and God willing. Your soul you'll have for eternity. That means we have to take belief a little more seriously than the decision of what color socks to wear today.
Rome has added so much to scripture that the volume of it written out and compared would far dwarf the Bible. Weigh that next to the law which is a small section of the first 2/3 of the bible and circumcision. Hmm. Accursed according to Paul, and thusly according to me. The Catholic people are my neighbors. I don't find that loving my neighbor includes lying to them to make them feel better about following lies. They deserve better than that and as it happens Christ requires it of me. It isn't much use to know the truth if you don't tell it. And part of that truth is that Christianity is pretty simple and straight forward. It is unchanging and so too is God. If you had a better perspective of it, you'd know that what you've said so far is so off base it isn't even funny.
Do you know scripture? Where on earth did you get this from? Wait, let me guess. You subscribe to the Catholic notion that Binding and loosing Gave the Apostles the right to stand in Mortal judgement over the sins of men after Christ had taught them to the contrary of this... That isn't in scripture.. any way shape or form. Furthermore, Binding and loosing per it's Judaic application (that's right, it is a Judaic term, not something drempt up in Chrisitianity) is a judicial term referring to the understanding of God's word. Beyond that, it is interpretive and only legislative to the extent of clarifying what is already there - not adding what is not. IE Rome may allow liberal judges to legislate from the bench; but, God does not. That was one of the big issues God had with the Pharisees and Saducees and he didn't come down here to die for us so he could correct it by letting it go on any further. He came down here to put a stop to that nonsense. It's not wise to edit God. When you speak or Do and God has not spoken or said to do, you're on Dangerous Ground - usually with a lion and donkey standing next to you!
