It's not an easy co-existence, Mr Gingrich. Some contrasts:
“Run for your life from any man who tells you that money is evil. That sentence is the leper's bell of an approaching looter.”
“For the love of money is a root of all kinds of evil, and in their eagerness to be rich some have wandered away from the faith,” – I Timothy 6:10.
“It is one’s own personal selfish happiness that one seeks, earns, and derives from love.”
“This is my commandment, that you love one another as I have loved you. No one has greater love than this, to lay down one’s life for one’s friends.”
“I swear, by my life and my love of it, that I will never live for the sake of another man, nor ask another man to live for mine.”
“Those who love their life lose it, and those who hate their life in this world will keep it for eternal life.”
It is possible to read the Gospels as entirely a personal and not political message, and certainly not view Christianity as a short route to socialism. But it is impossible even in one's personal life to be a Christian and to be a Randian. The whole point of the Gospels is that Rand's value system leads to profound misery and spiritual loss. And the whole point of Rand is that Nietzsche was onto something.
