So, you have never sinned?
Where in the flippin' blazes did you get the idea that I was saying I never sinned??? One of my main problems with the ancient churches during my search was that they didn't seem to think we were that messed up. Catholicism (not I) says that human nature was merely "wounded" by original sin (I grew up with Innate Total Depravity!). I explicitly said that since historical chrstianity acknowledged the teachings on human nature of the Talmud why in the name of all that's reasonable invent a new religion when there already was one?
Until Martin Luther chrstians lived their entire lives walking a tightrope over hell. There was no "assurance of salvation," no "eternal security," or any such thing. I feel like I'm telling a little kid there's no Santa Claus when I point out that Protestantism did not exist in the ancient chrstian world. All of ancient chrstianity--from Rome to Persia to India to Ethiopia--is about liturgies, sacraments, moral codes, and monasticism. The idea that Constantine is responsible for all that is ludicrous.
The only version of chrstianity that makes sense is inauthentic and ahistorical. Actual historic chrstianity replaced the Torah's morality and ritual with another morality and ritual, then threw a crucifixion on top of it and screamed about how the Jews had committed "the greatest crime in history" (I always thought he was vicariously eternally damned by G-d in our place, but this is another "invention").
Finally (and I know this is useless since you refuse to even think about it), the two quotes you offer are a perfect example of chrstian error on this subject. You believe they are from "the same identical bible" but they most assuredly are not. Hebrews says "without the shedding of blood there is no forgiveness of sin." Leviticus does not say that. It says that it is forbidden to eat blood because when an offering is made it is the blood (rather than the other parts) of the animal that makes atonement. This is not the same thing as saying "without blood there is no forgiveness of sin." You probably won't see it because you begin with an a priori belief in the "new testament." If you did not have that a prior belief you would see the difference.
I have devoted years on this forum to defending Fundamentalist Protestants and refuting their critics. I was broken hearted to learn the truth, but it's still the truth. Unless someone invents a time machine so they can go back and insert Protestantism into chrstianity's beginnings the real thing will be what it always was until 1517.
