The tough part of that quote is the part about remaining uncorrupted by the world, that is if you accept the Christian Bible as the literal word of God. If you do, then remaining uncorrupted brings in this quote from Matthew, Chapter 5:
17—Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them.
18—For truly I tell you, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished.
19—Therefore anyone who sets aside one of the least of these commands and teaches others accordingly will be called least in the kingdom of heaven, but whoever practices and teaches these commands will be called great in the kingdom of heaven.
—20 For I tell you that unless your righteousness surpasses that of the Pharisees and the teachers of the law, you will certainly not enter the kingdom of heaven.
Now the Law required that we stone to death all who commit adultery. It condoned slavery. It condemned all who eat shellfish or any seafood without fin and scale to death by stoning. Any child who is disrespectful of their parents is to be stoned to death. Likewise those who fail to keep the Shabbat. There’s really no exception made for that in the Christian Bible, changing the Shabbat from Friday before sunset to sunset on Saturday and making in Sunday instead. And by the way, when the Lord said no work, He mean NO WORK. We are all abominations and guilty of stoning for that one. Then there is wearing clothing of mixed fibers. Got any permapress? That is an abomination and merits stoning to death. Ever planted a flower garden? If you sowed mixed seeds to get a bouquet of color in your flowers, that’s an abomination too. Off to the stone pile for death.
As you may gather, while I grew up in the Christian tradition and studied it in some depth, I am not a Christian, But I do find one of Jesus’ attributed statements to be massively profound. He said in Matthew 7:12 “Therefore all things whatsoever ye would that men should do to you, do ye even so to them.” That is the basis of our commonly quoted Golden Rule, “Do unto others as you would have them do unto you.” If you were an orphaned child, would you want someone to help you make your way into adulthood, or would you want them to just abandon you to starvation or a life as a street urchin stealing bits of food?
Now this thought was hardly original to Christianity or even Judaism. It came into the thinking of the Jewish people in their wanderings in ancient Egypt, Babylonia and was also held as a truth by the ancient Greeks. It is also found in religious texts from Hinduism, Jainism, Buddhism, Islam, Confucianism, Mohism, Sikhism and Taoism, to name a few. Wicca as well, though it is unclear how far that part of Wiccan tradition stretched back.
Modern secular-humanist atheists see the obvious logic of this one, simple rule as the basis of all reasoned moral law. To me it is quite unreasonable to stone someone to death for eating lobster, or enjoying pork rinds. Likewise, for mowing his grass on a Sabbath or a Sunday. I wouldn’t want him to do that to me. So I wouldn’t do it to him. So you are going to have to define “Corrupted by the world” for me before I will buy into that part of it.
