the romans and greeks also valued law and order. this is not something the christians came up with. and every society values the sanctity of life. they had to in order to continue existing. if they didn't there would be no gentiles to convert, because they would never have been born. they just didn't value all life equally like modern christians do. charity? okay, i'll give that to the christians. they did come up with that one. but even that doesn't need to be a mandate from god. you can find secular reasons to justify it. i shouldn't have to worship a foreign god to adopt these concepts.
