“First, you have ignored all of the times when Christianity wasn’t supporting equality;”

It’s true that MAINSTREAM CHRISTIANS wasn’t supporting equality sometimes in history. That’s because they were not true to the Bible.

“To apply your rationality to religion, shouldn’t Christians be showing a little more respect to the religions that it borrowed from? I think there may be a long line of mythical sacrificed sons living out the hero cycle of death and rebirth that want their identity back. Also, I think the concept of a higher being was originally that of a fertility goddess; you may want to change the gender of your deity. “

How do you know who borrowed from who? The fact that archaeology discovered older writings from other cultures it’s not an argument. Because you didn’t discover a proof it doesn’t mean it never existed. If you didn’t discover a wire you can’t say they used wireless technology

You treat superficially the sacrifice of Jesus. It’s completely different than a pagan sacrifice. You ignore the theology and the motivation behind it.

The last but not the least, the principles of Christian religion existed since the creation of the human being. Some people followed it strictly, some corrupted it into other human made religions.

“You say that Christianity made ethics”

No, he doesn’t. God made “ethics” and made it known to the human world through Christianity (true Christianity).

“Now, please tell me what’s wrong with the concept of basing ethics on a common desire to live. If you aren’t alive, then there’s nothing left to argue about. If you are alive, it’s because you have done what is required to stay that way. “

If survival is the supreme goal, then it would be “right” to kill, to steal, to lie etc. There is no place for mercy, kindness, rightness etc. And there would be no place for equality either. You kill the weaker and run off the stronger. Or get eaten.

So, in short, this is the answer.

P.S. I’m not an English native speaker, so please excuse my mistakes.

First, you have ignored all of the times when Christianity wasn’t supporting equality; the long history of intolerance towards contradicting ideals. Second, you are ignoring that if you weren’t Christian in the societies that many of these rights came from, you’d find yourself in some very uncomfortable circumstances. These societies could only advance under Christianity or other Abrahamic beliefs. None of the above is the biggest flaw in what you’re saying though.

The real issue is that you come to an ad verecundium and a nice hurdle jumping of improper transposition that illustrates the point you’re debating against. You say that Christianity made ethics, therefore it should be respected to the point of being required for ethics. It seems as if this never occurred to you as an issue.

To apply your rationality to religion, shouldn’t Christians be showing a little more respect to the religions that it borrowed from? I think there may be a long line of mythical sacrificed sons living out the hero cycle of death and rebirth that want their identity back. Also, I think the concept of a higher being was originally that of a fertility goddess; you may want to change the gender of your deity.

Now, please tell me what’s wrong with the concept of basing ethics on a common desire to live. If you aren’t alive, then there’s nothing left to argue about. If you are alive, it’s because you have done what is required to stay that way. From there, doesn’t the common drive to live combined with theory of mind provide for what you would call the golden rule? What higher good is there than providing the greatest freedom to the individual, paired with the responsibilities of not interfering with that of others?

So, in short, where is the necessity of Christianity in ethics?
