The Incompatibility of Christian Morality and Evolutionary Morality

Christianity pretty explicitly states that moral acts should be done for no reason other than that being moral is good/god says, “go be moral.”

“So when you give to the poor, do not sound a trumpet before you, as the hypocrites do in the synagogues and in the streets, so that they may be honored by men. Truly I say to you, they have their reward in full. “But when you give to the poor, do not let your left hand know what your right hand is doing, so that your giving will be in secret; and your Father who sees what is done in secret will reward you.” Matthew 6:2-4

“Do not neglect to do good and to share what you have, for such sacrifices are pleasing to God.” Hebrews 13:16

“Jesus looked up and saw the rich putting their gifts into the offering box, and he saw a poor widow put in two small copper coins. And he said, “Truly, I tell you, this poor widow has put in more than all of them. For they all contributed out of their abundance, but she out of her poverty put in all she had to live on.” ” Luke 21:1-4

“But if anyone has the world’s goods and sees his brother in need, yet closes his heart against him, how does God’s love abide in him?” 1 John 3:17

“Sell your possessions, and give to the needy. Provide yourselves with moneybags that do not grow old, with a treasure in the heavens that does not fail, where no thief approaches and no moth destroys.” Luke 12:33

“A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another. By this all people will know that you are my disciples, if you have love for one another.” John 13:34-35

“Now the full number of those who believed were of one heart and soul, and no one said that any of the things that belonged to him was his own, but they had everything in common. And with great power the apostles were giving their testimony to the resurrection of the Lord Jesus, and great grace was upon them all. There was not a needy person among them, for as many as were owners of lands or houses sold them and brought the proceeds of what was sold and laid it at the apostles’ feet, and it was distributed to each as any had need.” Acts 4:32-35

“For what will it profit a man if he gains the whole world and forfeits his soul? Or what shall a man give in return for his soul?” Matthew 16:26

“You have heard that it was said, ‘You shall love your neighbor and hate your enemy.’ But I say to you, Love your enemies and pray for those who persecute you, so that you may be sons of your Father who is in heaven. For he makes his sun rise on the evil and on the good, and sends rain on the just and on the unjust. For if you love those who love you, what reward do you have? Do not even the tax collectors do the same? And if you greet only your brothers, what more are you doing than others? Do not even the Gentiles do the same?” Matthew 5:43-48

“The second is this: ‘You shall love your neighbor as yourself.’ There is no other commandment greater than these.” Mark 12:31

The result, of course, is that Christian morality is very communist, and anyone who says otherwise is lying or ignorant. Self-interest is occasionally referenced so far as to say, “don’t worry about giving everything you have away, because god will make sure you don’t starve as a result,” but the general thrust of “don’t store up money, don’t do things for material rewards, take care of each other without regard to whether or not you can pay each other back, don’t make a big public deal out of your piety and generosity, etc.,” is pretty consistent.

Christianity is not necessarily quite on board with “treat everyone on earth equally,” since it is coming out of an explicitly ethno-nationalist religious tradition, but it is clearly moving in that direction.

In western society, this leads to a generalized notion that good deeds should be done for their own sakes, that seeing “gifts” as social exchange is bad and that all gifts should be given without strings attached, etc. Since this contradicts reality, people end up fighting over the implications of, say, buying someone dinner.

In reality, while some true charity and kindness exists (and I encourage it to,) most morality exists because we are descended from people who acted that way. We don’t actually take care of our children because of some divine command to do so, but because people who take care of their children historically had more surviving children than people who didn’t, and thus we are descended from people with child-rearing instincts.

The notion that morality is actually a self-interested attempt by our genes at continued propagation conflicts directly with our cultural, Christian norms of morality.

In general, Christian morality is probably a decent kludge, but forgetting reality is not good. If a moral system leads to its followers actually reproducing less than others (say, Shakerism,) then of course the result is that the followers of that morality die out.
